But the question of bin Laden’s effectiveness is a deceptively complex one. It begs the question: how much did his death matter? When scholars and practitioners examine terrorist leader effectiveness, it is generally assessed according to metrics such as the number of attacks, the lethality of attacks conducted under their leadership, or the duration of their tenure.
However, these metrics would not capture the most consequential event since bin Laden’s death: the split between Al Qaeda and the Islamic State, an outcome often assumed to be the culmination of strategic differences between the two groups. What is less often discussed about leadership effectiveness—but is perhaps more important—is the leader’s influence over both internal group cohesion as well as external relations with other groups. Both factors, internal unity and external relationships, are essential indicators of a leader’s effectiveness. As such, bin Laden’s greatest strength as the leader of Al Qaeda was the masterful way in which he cultivated and reinforced internal and external unity, successfully managing difficult personalities within his group and within allied groups. In particular, bin Laden was instrumental in keeping Al Qaeda and its Iraq affiliate allied despite their longstanding problems and strategic differences. Viewing unity as paramount, bin Laden handled disputes more deftly than his deputy and successor Dr. Ayman al-Zawahiri. With bin Laden’s credibility, diplomacy, persuasiveness, and overall ability to manage the conflict, these now foes would likely have remained aligned, despite the conflict between al Nusra and the Islamic State in Iraq and al-Sham (ISIS) that led to the alliance’s rupture.
In addition, although decapitation is still one of the most relied on counterterrorism measures, the focus has largely been on the targeted leaders. Far less attention has been given to examining the value of removing the current leader against the question of who will take his or her place. In making this determination, policymakers and analysts must consider not only operational factors like lethality but also organizational factors. A question of particular importance is: how well does the leader manage the internal and external relations of the group compared to the likely successor?
This article starts from the assumption that first image theorizing—examining the impact of individuals on outcomes—can illuminate critical aspects of terrorist groups and can also inform counterterrorism decision making. While some political scientists and international relations (IR) scholars diminish or outright ignore individuals as a force shaping major international events,
1. Daniel L. Byman and Kenneth M. Pollack, “Let Us Now Praise Great Men: Bringing the Statesman Back In,” International Security 25(4) (Spring 2001), p. 108.View all notes
first image theorists have argued that, even at the state level, individuals play an important role in forming—and fracturing—alliances. Morgenthau observed that “the smooth and effective operation of an alliance, then, depends in good measure upon the relations of trust and respect among its military statesman.”

Likewise, Byman and Pollack argue that leaders shape alliances and exert significant influence on strategies, goals, and capabilities.

If leaders even matter for states’ alliances, they undoubtedly matter for terrorist organizations’ relations as well. As Price argues, the inherent cohesiveness of violent groups, the intentional centralization of authority and information, and the importance of leadership in defining the group’s ideology and driving recruitment all make terrorist leaders extraordinarily consequential.

In an environment where the individual possesses exceptional weight, the first image seems especially germane for the study of terrorist groups. Moreover, given that terrorist organizations with allies are “more likely to kill, more likely to kill prolifically, and more likely to pursue weapons of mass destruction,” not to mention survive longer, it is essential to understand the role leaders play in alliance sustainment.5

Examining the Al Qaeda and ISIS alliance rupture through a first image lens and using counterfactual analysis, this article’s findings broadly suggest:
How leaders matter relates to how they manage their organizational relations—both internal and external—rather than simply the number or type of attacks a group plans and executes under a leader.
Bringing leadership back into the study of terrorism is critical given the concentration of power in the hands of individual terrorist leaders.
Terrorist leaders can be evaluated on their ability to manage internal cohesion and external relations.
A pivotal moment in assessing the importance of terrorist leadership is the dispute between al Nusra and ISIS that led to the alliance rupture between Al Qaeda and ISIS. It was al-Zawahiri’s biggest challenge to date as Al Qaeda’s leader. Without question, the alliance between Al Qaeda and its Iraq affiliate had long been troubled, leading some to conclude that the break was a long overdue culmination of strategic differences. However, long-standing differences between Al Qaeda and ISIS about levels of violence, state declarations, or priorities were not previously sufficient to cause an alliance rupture. Nor was recalcitrant leadership in Iraq a new development. What changed was Al Qaeda’s ability to manage these problems as a result of bin Laden’s death and al-Zawahiri’s ascension.
This article examines what impact bin Laden’s death had on the alliance rupture between Al Qaeda and ISIS. The driving question is: could the alliance outcome have been different if bin Laden were still alive? This article answers this question by employing counterfactual methodology to systematically test what impact bin Laden in particular had on the Al Qaeda–ISIS alliance. It thus process traces alternate outcomes from this pivotal event in the recent history of terrorism. It then briefly surveys the literature on first image theories, including the implications for leadership decapitation. The article then examines why counterfactuals provide a much needed—yet rarely used—approach to examining critical issues such as the importance—or lack thereof—of terrorist leaders in alliance management. It offers a typology of potential outcomes: bin Laden—Alliance, bin Laden—Split, al-Zawahiri—Alliance, and al-Zawahiri—Split (Table 1). It first examines events as they transpired in the al-Zawahiri—Split Quadrant, before engaging in comparative counterfactual process tracing of the bin Laden—Alliance and bin Laden—Split Quadrants to discern whether bin Laden’s survival would have altered the outcome. Bin Laden was an effective leader of Al Qaeda, though not only for the reasons often attributed to him. Perhaps his greatest strength was managing conflict and disunity, which would erupt after his death. This investigation of his impact is not an esoteric exercise. Groups with allies pose the greatest counterterrorism threat today and understanding what sustains or disrupts these relationships is thus of paramount importance.
The Importance of Terrorist Organization Leaders
IR scholarship has generally eschewed first image explanations when it comes to matters such as alliances and wars, with a few important exceptions. In particular, in “Let Us Now Praise Great Men,” Byman and Pollack argue, “goals, abilities, and foibles of individuals are crucial to the intentions, capabilities, and strategies of a state.”6
6. Byman and Pollack, “Let Us Now Praise Great Men,” p. 144.View all notes
Byman and Pollack maintain that individuals can both determine a state’s intentions and be an important component of a state’s capabilities, saying “[g]reat leaders also can strengthen a country’s diplomatic power. It is individuals who build alliances … that maintain or destroy balances of power.”7

Horowitz et al. similarly analyze world leaders to demonstrate that their beliefs, worldviews, and acceptance of risk help determine when and why states wage war.

However, scholarship on terrorism has followed the trends within IR, and relatively few recent scholarly works emphasize terrorist leaders. With far fewer constraints than heads of state and less impact on international balances of power, the leader of a violent political group can have an even greater impact on that group’s preferences, intentions, strategies, and by extension, its alliances. Therefore, the neglect of first image explanations limits an understanding of terrorist group relations.
The main exception to this tendency to overlook terrorist group leaders is the research program on leadership decapitation. This literature is replete with debates and varying findings, with conclusions often depending on how one measures the effect of leadership decapitation. Proponents of leadership decapitation point to examples of groups like the Kurdistan Workers Party (PKK), Sendero Luminoso, the Fuerzas Armadas Revolucionarias de Colombia (Revolutionary Armed Forces of Colombia—FARC), and Aum Shinrikyo, in which the arrest of the charismatic, central leader severely damaged the group. Price finds that leadership decapitation increases the mortality rate of terrorist groups, because the organizational characteristics of terrorist groups amplify the importance of leadership and complicate succession.14

Langdon et al. also find support for decapitation, arguing that the killing of the leader is more likely to prompt the group’s failure than his arrest.15

Nor did it destroy the Sunni jihadist movement. By those measures, his death was not consequential. However, no evidence exists that his death bolstered Al Qaeda’s recruitment or the group’s rate of attacks either. So how did bin Laden’s death affect Al Qaeda?
Counter to Jenkins’s prediction, bin Laden’s death resulted in a less capable leader rising to the helm of an already weakened group, a leader who has struggled to manage an organization under long-term pressure and facing an upstart. To state the obvious: all leaders are not created equal.28
28. Jeff D. Colgan and Edward R. Lucas reach such a conclusion in analyzing the disparate third and first image effects of revolutions on a state’s behavior. In particular, Colgan and Lucas find that revolutionary leaders are less likely to form new alliances. See Jeff D. Colgan and Edward R.

While the removal of even an exceptional leader may not result in the dissolution of the group s/he leads or an end to its violence, leadership decapitation can weaken a group by eroding its ability to manage challenges and conflict when a less capable successor takes over the group. In other words, the efficacy of leadership decapitation depends on the quality of the targeted leader compared to his or her successor. Of course, this impact cannot necessarily be quantified in terms of numbers of attacks, deaths, or organizational survival. One area that leadership capability can reveal itself, however, is in managing relations and conflicts.29

Why Comparative Counterfactual Analysis?
In order to examine how bin Laden’s death affected Al Qaeda and, most significantly, the Al Qaeda–ISIS split, it is critical to hypothesize scenarios in which bin Laden did not die. Counterfactual analysis assesses the extent to which the absence of a condition—one deemed necessary for the original outcome to happen—is sufficient for the absence of the original, historical outcome. A counterfactual alters or removes one or more conditions from a course of past events to prompt a “possible” or “alternate” outcome.33
33. Jack S. Levy, “Counterfactuals, Causal Inference, and Historical Analysis,” Security Studies 24(3) (2015), p. 379.View all notes
While often applied to the past, counterfactuals can also treat future scenarios (e.g., “If Japan acquires nuclear weapons, then Asia will be destabilized”). At a basic level, counterfactuals can challenge determinism in causal analysis and the perceived inevitability of a course of events.
Scarcely has a method been as maligned as counterfactuals. Historian Carr dismisses the use of counterfactuals as the “might have been” school of thought, or an undisciplined “parlor game” that is only played by people who wish a more agreeable outcome had happened.34

However, this article contends as other scholarship has concluded: the responsible and disciplined use of counterfactuals can challenge deterministic views of historical events, elucidate false assumptions in causal analysis, and help analysts, policymakers, and scholars identify decisive factors and red herrings in complex security issues. Although skeptical of individual leaders’ relevance to explaining state behavior, Jervis identifies counterfactuals as an appropriate method for determining whether “the identity of the president or any other leader matters.”36

Of course, the U.S. military and intelligence community would likely still have pursued bin Laden if the May 2011 operation failed. However, for the sake of this study—and to avoid falling down a rabbit hole—the article will simply assume that bin Laden was not killed in 2011 and had survived through at least 2014.
The viability of a counterfactual addressing the alliance outcome between Al Qaeda and ISIS is matched by its utility. Examining terrorist groups via counterfactuals offers similar advantages as alternative analysis approaches in intelligence assessments, such as counterfactuals, devil’s advocacy, and Team A/Team B Exercises. These techniques can facilitate causal analysis, overcome deterministic biases, and inject creativity into the analytical process.45

To conduct comparative counterfactual analysis, the article process traces two counterfactual scenarios, bin Laden—Alliance and bin Laden—Split. First, it recounts what actually transpired, the al-Zawahiri—Split Quadrant, relying on secondary literature. For the comparative counterfactual analysis of the bin Laden—Alliance and bin Laden—Split Quadrants, it draws extensively from the declassified documents retrieved from bin Laden’s compound in Abbottabad, from the Harmony collection at West Point, and to a lesser extent public statements from Al Qaeda, al Nusra, and ISIS. The documents from Abbottabad are particularly useful in understanding how bin Laden viewed various situations, his management of the organization and relations with Al Qaeda’s allies, and the input he received from his senior lieutenants. It also uses secondary sources, including biographies of bin Laden and al-Zawahiri, for information about their leadership styles and capabilities. It will not examine the al-Zawahiri—Alliance Quadrant because the two variables of interest—strategic differences and leadership qualities—do not change. As the article will demonstrate, al-Zawahiri’s approach, personal idiosyncrasies, and decades of experience with multiple terrorist organizations shaped how he handled the conflict between al Nusra and ISIS. Therefore, the al-Zawahiri—Alliance Quadrant requires the pivotal juncture with al Nusra and ISIS to have never occurred at all, and such anomalies are not in the interest of this study.
The Al Qaeda and ISIS Split: What Happened
This section briefly explains the events as they actually occurred leading up to alliance break, corresponding with the al-Zawahiri—Split Quadrant, picking up the timeline shortly after bin Laden’s death in May 2011. The Islamic State in Iraq (ISI), as the group was then known, was the only affiliate that did not publicly declare bayat, or fealty, to al-Zawahiri when he was announced as Al Qaeda’s emir that June. Although Al Qaeda contended that ISI’s leader Abu Bakr al-Baghdadi privately pledged bayat to al-Zawahiri and thereby complied with al-Zawahiri’s decision to keep the bayat a secret, there is a dispute about whether al-Baghdadi actually did so.47

While this may appear to be a technicality, breaking bayat is a serious breach that would badly damage one’s standing in jihadistcircles.48

The Arabic word bayat (also written bay’at, bayah, and bay’ah) describes the pledge of allegiance one makes to a leader—usually a spiritual leader or sheikh from whom one receives knowledge—and can be understood as a promise made to God. Bayat is not a one-sided declaration and requires the oath to be accepted to be rendered legitimate.View all notes
Although there was no public bayat, ISI issued a public statement proclaiming that it remained faithful to al-Zawahiri and Al Qaeda.49

That same month, in part at al-Zawahiri’s urging, al-Baghdadi deployed Syrian operative Abu Muhammad al-Jolani and a dozen others to Syria—where the revolution against Bashir al-Assad’s regime had escalated into a full-fledged civil war—to wage jihad against the Alawite government.51

What al-Baghdadi’s spies found clearly did not alleviate ISI’s concerns, because in March 2013, al-Baghdadi and his deputy met with al-Jolani in Syria and reiterated their request that he publicly acknowledge the ties between al Nusra and ISI. This time al-Jolani refused by appealing to a higher authority, arguing that al Nusra was in Syria on al-Zawahiri’s orders and that al-Zawahiri had forbidden any announcement of Al Qaeda’s presence in Syria.56

[W]e could not but come to their [the people of Syria’s] help so we appointed al-Jolani, who is one of our soldiers, along with a group of our sons, and we sent them from Iraq to Syria to meet our cells in Syria.

At an impasse, al-Baghdadi and al-Jolani appealed to Al Qaeda. This move belies the notion that the alliance between Al Qaeda and ISIS was already irrelevant, despite the ambiguity about al-Baghdadi’s oath. Al-Jolani called on the “sheikh of jihad,”61

while al-Baghdadi wrote to al-Zawahiri, foreshadowing the strife that would follow:
This poor servant [al-Baghdadi] and those brothers with him here in al-Sham believe it is up to our shaykhs in Khorasan [Afghanistan and Pakistan] to announce a clear, unambiguous position in order to bury this conspiracy before it causes blood to flow and we become the reason for a new calamity for the umma. We believe that any support for what this traitor has done, even tacitly, will lead to a great fitna, which will thwart the program for which the blood of Muslims has been shed.62

Now their problems were quite public.
The problems between ISIS and al Nusra mounted. Many of al Nusra’s non-Syrian members defected to ISIS. As al-Baghdadi forewarned, ISIS proceeded to use violence against Syrian opposition groups, including al Nusra, to back up its territorial claims. By early 2014, it had incited “a war within a war” in northern Syria.”72

Irrespective of ISIS’s gains, Al Qaeda officially severed ties in February 2014, slightly more than ten years after the alliance formed, declaring that ISIS “is not a branch of the al Qaeda group … does not have an organizational relationship with it and [Al Qaeda] is not the group responsible for their actions.”77

While ISIS clashed with al Nusra on the battlefield, it expressed its ire with Al Qaeda in the media.

The Cause of the Split: The Strategic Explanation
This section offers the first part of the comparative counterfactual analysis, laying out the logic of the bin Laden—Split Quadrant, arguing that Al Qaeda and ISIS would have inevitably experienced the break because of their strategic differences, even if bin Laden was alive.82
82. Byman, “Will ISIS and al-Qaida Always Be Rivals?,” 27 May 2016, Brookings Blog. Available at https://www.brookings.edu/blog/markaz/2016/05/27/will-isis-and-al-qaida-always-be-rivals/(accessed September 15, 2017); Barak Mendelsohn, “Jihad’s Civil War: The Battle Between ISIS and al Qaeda Simmers On,” Foreign Affairs, 16 June 2016.

Stern and Berger capture this rationale when they characterize the Al Qaeda and ISIS break as “born out of strife and irreconcilable differences.”83
83. Stern and Berger, ISIS, p. 177.View all notes
Overall, the two groups experienced three major strategic differences. First, they disagreed about which enemy to prioritize. Second, they disagreed about the appropriate quantity and quality of violence. In particular, Al Qaeda was continually concerned with Al Qaeda in Iraq (AQI)/ISI’s level of violence against Muslims. Third, they disagreed about whether the conditions were ripe for declaring and building a state. Al Qaeda believed it was premature to declare a state, whereas the group in Iraq was willing to make such a declaration even when it lacked the basic trappings of a state. In 2013, these three differences re-emerged.
Moreover, these differences converged at a time in which al Nusra had demonstrated its desirability as an ally, discouraging Al Qaeda from allowing the problematic ISI to subsume al Nusra. According to the logic of this Quadrant, no matter who led Al Qaeda, it would have sought its own ally in Syria to influence events there and retain its preeminence among jihadist groups. As occurred in 2003, when Al Qaeda was unable to directly participate in the insurgency in Iraq, it sought a representative in Syria through which it could shape the conflict. Al Qaeda long sought to influence local insurgencies, and, like Iraq in 2003, Syria was a particularly strategic and symbolic battlefield.84

Al Nusra’s conduct and adherence to Al Qaeda’s strategy demonstrated that it was a desirable partner for this venture. Unlike its counterpart in Iraq, it comported with the strategy that Al Qaeda advocated. Specifically, it appointed indigenous leadership, forged ties with fellow Sunni groups, and carved out a leading and unifying role among Sunni opposition groups—approaches Al Qaeda had urged AQI/ISI to take with limited success.86
86. Al Qaeda advocated for Iraqi leadership of AQI even when al-Zarqawi headed the group. See Ayman al-Zawahiri, Letter to Abu Musab al-Zarqawi, 9 July 2005, Combating Terrorism Center at West Point.

In addition, Al Qaeda knew and trusted several al Nusra associates, most notably Abu Khalid al-Suri. By this logic, bin Laden would have ruled as al-Zawahiri in the dispute—that al Nusra should be independent from ISI—so that Al Qaeda could protect al-Nusra as partner in Syria. This would have triggered al-Baghdadi’s ire and public denunciation and led to the alliance termination.
The argument underpinning this Quadrant is that al-Baghdadi’s public power play to absorb al Nusra, declare a state spanning Iraq and Syria, and use violence against Sunni opposition groups that did not acquiesce to ISIS was thus the proverbial last straw. With these events, their strategic differences became insurmountable.89

Problems with the Strategic Explanation
Undoubtedly, from the outset, Al Qaeda and AQI had a troubled alliance. Their strategies and priorities were never fully aligned. However, al-Zarqawi was clear about his intentions when he proposed the alliance in 2003, so these differences should not have been a surprise to Al Qaeda.91

The main points of tension in the relationship in 2013—ISI’s excessive violence, the two groups’ differing priorities, ISI’s tendency to make major decisions without consulting Al Qaeda, and a recalcitrant leader on the Iraq side—were by no means new issues. These had long been points of frustration between the two groups; however, under bin Laden, they were insufficient to end the alliance. Some terrorism scholars, such as Hoffman, debate whether their differences actually amounted to strategic disagreements or if they simply boiled down to “timing and process.”92
92. Bruce Hoffman, “The Coming ISIS-Al Qaeda Merger,” Foreign Affairs, 29 March 2016. Available at https://www.foreignaffairs.com/articles/2016-03-29/coming-isis-al-qaeda-merger(accessed September 15, 2017).View all notes
Even if one accepts them as strategic differences, it is unclear why these existing differences would have become irreconcilable in 2013 if bin Laden was still alive.
Divergent Views on Acceptable Levels of Violence
Although concerned about counterproductive violence against Muslims, bin Laden’s management of the alliance with AQI/ISI and other groups while he was alive suggests that ISIS’s excessive violence would not have been sufficient to cause the groups to split under his leadership. Under al-Zarqawi, AQI’s violence was so damaging to Al Qaeda that the former head of the bin Laden unit at the Central Intelligence Agency, Michael Scheuer, characterized al-Zarqawi as “the most potent strategic threat al Qaeda faced after 9/11.”93
93. Michael Scheuer, Osama bin Laden (New York: Oxford University Press, 2011), p. 141.View all notes
Despite the damage AQI under al-Zarqawi inflicted on Al Qaeda, bin Laden repeatedly counseled AQI through his deputies with limited, if any, success to better calibrate its violence against Muslims; he did not sever ties, nor did he threaten to do so.
AQI’s indiscriminate and excessive violence persisted after al-Zarqawi’s death, when Abu Ayyub al-Masri and Abu Omar al-Baghdadi took over.94
94. Scott-Clark and Levy, The Exile, p. 276View all notes
During their tenure, the group, now having declared itself a state and thereby deemphasizing its association with Al Qaeda, lost much of the prestige it garnered from al-Zarqawi’s leadership and faced a revolt from Iraqi Sunnis—the exact outcome Al Qaeda forewarned the group to avoid.95

Other Al Qaeda members saw ISI’s violence as too much of a liability, but could not prevail on bin Laden to end the alliance. Adam Gadahn wrote to bin Laden urging him to break ties with ISI because of its violent excesses.96

Despite ISI’s continued misconduct, bin Laden remained unwilling to sever ties. In other words, the problem of excessive violence existed when AQI was at a peak under al-Zarqawi and when ISI was at an ebb under al-Masri, yet bin Laden did not break ties at either point, nor is there evidence that he seriously considered doing so. Bin Laden was steadfast even as the group in Iraq experienced dramatic changes in its strength.97
97. In addition, while one might argue that ISIS had surpassed Al Qaeda in 2013–2014, that was also the case in 2004–2006, during al-Zarqawi’s meteoritic rise and Al Qaeda’s post-9/11 “meager years.” (see Wright, “The Master Plan”). Senior Al Qaeda leader Abu Faraj al-Libi acknowledged as much when he remarked, “[h]ad I known of all of Zarqawi’s activities and capabilities when he first came to al Qaida with a desire to pledge bayat to Usama bin Laden, I would have written a letter to bin Laden advising that the Shaykh [bin Laden] pledge bayat to Abu Musab instead” (Seth Jones, Hunting in the Shadows (New York: W. W. Norton Company, 2012), p. 145).View all notes
Bin Laden undoubtedly would have been dismayed that the problem continued under Abu Bakr al-Baghdadi; however, his handling of the alliance until that point suggests that ISIS’s excessive violence would not suffice to end the alliance.
Instead, bin Laden’s track record suggests that he would have focused on persuading ISIS to modify its behavior. To that end, Al Qaeda repeatedly sent emissaries and letters and investigated allegations.98

In the correspondence available, under bin Laden, Al Qaeda did not communicate with AQI/ISI in such a manner. Yet, even in the case of the Pakistani Taliban, which continued to engage in indiscriminate violence despite Al Qaeda’s admonitions, bin Laden did not follow through on threats to punish the Pakistani group or break ties. Despite concern about his allies’ violence,106

bin Laden’s strategy was to provide counsel and seek ways to persuade others to reform.107

The second long-standing issue between Al Qaeda and AQI/ISI was the difference in their priorities. This initially manifested itself in Al Qaeda’s desire for AQI to focus on the United States’ forces in Iraq, while AQI concentrated on the Shi’a. The disagreement shifted slightly when AQI renamed itself ISI, thereby claiming to be a state, which Al Qaeda viewed as premature. From Al Qaeda’s standpoint, the United States must first be sufficiently weakened before forming an Islamic state.
We should stress on the importance of timing in establishing the Islamic State. … We should keep in mind that this main power [the United States] still has the capacity to lay siege on any Islamic State, and that such a siege might force the people to overthrow their duly elected governments. We have to continue with exhausting and depleting them till they become so weak that they can’t overthrow any State that we establish.108

Despite these reservations, bin Laden not only maintained the alliance with ISI, he ordered his lieutenants to defend AQI’s decision to declare itself ISI and even provided the language for al-Zawahiri to use to justify its ally’s declaration.
[I]t had to establish in Iraq a state and an emir to rule these people and facilitate their affairs and preserve sharia law. The trustworthy mujahidin in Iraq have vouched for individuals and have established the state and have agreed upon an emir from among them who is Abu ‘Umar al-Baghdadi. As for the emir of war in Iraq, we know him and have vouched for him publicly in both video and audio throughout the world.109

In addition, pointing to Al Qaeda and ISIS’s disagreement over which enemies to prioritize and whether to establish an Islamic state as the cause of the alliance rupture overlooks that Al Qaeda experienced these differences with other allies as well.

Moreover, despite bin Laden’s reservations about premature state building, he balanced his opposition by supporting affiliates when they did control territory. For example, bin Laden assigned one of Al Qaeda’s most respected religious scholars, Abu Yahya al-Libi, to support al-Shabaab’s administration of territory.113

In other words, like the issue of excessive violence, the divergence in Al Qaeda and ISIS’s priorities and beliefs about the timing of erecting an Islamic state was a long-standing and manageable issue. Nor was it unique to Al Qaeda’s alliance with ISIS. Yet, these differences never induced an alliance termination. Instead, under bin Laden, Al Qaeda engaged in dialogue about its views and vision and sought to influence its allies’ conduct.114
114. For example, see Osama bin Laden, Letter dated 07 August 2010, 7 August 2010, “Bin Laden’s Bookshelf,” Office of the Director of National Intelligence. Available at https://www.dni.gov/files/documents/ubl/english/Letter%20dtd%2007%20August%202010.pdf(accessed September 15, 2017).View all notes
Moreover, some of the differences between Al Qaeda and ISIS’s priorities actually narrowed after bin Laden’s death. While bin Laden advocated the America-first strategy, al-Zawahiri prized the overthrow of the Egyptian regime, a cause he relinquished only when he had exhausted all other options. Like al-Baghdadi, al-Zawahiri saw the utility of greater focus on the near enemies in the Arab world, particularly after the Arab Spring.115

Lack of Consultation
The third major and recurring problem in the alliance was AQI/ISI’s lack of consultation with Al Qaeda. Over the course of the alliance, AQI/ISI failed to confer with Al Qaeda about numerous major issues: the decision to launch an attack in Jordan in 2005; the successor to al-Zarqawi in 2006, Abu Umar al-Baghdadi in 2010, and Abu Ayyub al-Masri in 2010; and the decision to declare an Islamic State in Iraq in 2006, to name a few. Therefore, al-Baghdadi’s move to declare an Islamic state extending into Syria was not an isolated incident, it was the latest in a series of unilateral moves by the group.
While AQI/ISI’s lack of consultation caused Al Qaeda consternation,116

By the time al-Baghdadi took over, Al Qaeda had adjusted to ISI’s consultation failures to some degree. While Al Qaeda offered its views to ISI about how to select the next leader, in a letter between Al Qaeda senior leaders in 2010, the author denied asking ISI to a delay in the announcement of its new leader in order to consult with Al Qaeda.
In reference to my request to the brothers in Iraq to hold back on announcing the emir, I did that in order to protect the unity of Al-Mujahidin there, and not to have discussions with us on this. … As far as what you mentioned regarding the cons in delaying the announcement of the Amir, we have no doubt about that.120

In other words, while bin Laden would have been dismayed by ISI’s decision to unilaterally expand its writ to Syria, he previously handled ISI errors that were committed without consulting Al Qaeda by privately communicating his concerns through his lieutenants and offering guidance on how to reform going forward.
Problematic leaders from the Iraq side also proved an ongoing issue. Al Qaeda had also found it difficult to deal with al-Zarqawi, al-Masri, and Abu Omar al-Baghdadi. Abu Bakr al-Baghdadi’s messiah complex was undoubtedly a difficult challenge, but bin Laden possessed, as Byman explained, the rare qualities necessary to unify “a movement filled with strong and zealous personalities.”121

In other words, bin Laden prioritized supporting ISI, even when relations were strained.
In sum, the main factors identified in the strategic explanation as causing the split had been managed under bin Laden for years. Above all, bin Laden was intent on shaping the conduct of other groups and thus had proven averse to severing ties.
Could the Alliance have been Salvaged? A First Image Examination
In contrast to the strategic explanation, a first image argument emphasizes the influence of leaders on outcomes, such as alliance and conflict management. Even some proponents of the strategic explanation acknowledge that leadership played a role in the Al Qaeda and ISIS split. Stern and Berger point out, “[w]hile it’s true to say that al Qaeda saw ISIS as too extreme, it’s more accurate to say that al-Zawahiri fired ISIS for its public defiance of his wishes and commands.”130

In other words, leadership played an important role in the cessation of the alliance. In this section, the article first presents evidence that suggests that bin Laden would have viewed the al Nusra and ISIS dispute differently than al-Zawahiri. In the second section, it compares the leadership qualities of bin Laden and al-Zawahiri, in particular, it examines their respective abilities to handle conflict and thereby salvage the alliance.
Evidence of how Bin Laden would have viewed the Dispute
Although al-Nusra had proven a more desirable partner than ISIS, al-Zawahiri’s decision to separate ISIS and al Nusra was inconsistent with bin Laden’s views in two notable ways. First and foremost, endorsing a split between al Nusra and ISIS ran counter to bin Laden’s unwavering promotion of unity, which he viewed as a strategic necessity, a religious requirement, and an organizational imperative. A public statement to the “Islamic Nation” captured his view:
I remind the Mujahidin that uniting under unification is not a minor thing, but rather one of the most important duties. Therefore, it should be given attention, and the Jihadi organizations must unify and arrange among each other to get united, under one banner.132

Bin Laden had parochial reasons for seeking unity: it was a means to bring other groups under Al Qaeda’s rubric. For example, in urging the Libyan Islamic Fighting Group to merge with Al Qaeda, bin Laden told al-Zawahiri to “please remind them that unity is a duty and it should not be postponed.” He similarly characterized al-Zarqawi’s alliance with Al Qaeda as a reflection of “the duty of unification.”133

At the time of bin Laden’s death, Al Qaeda had four affiliates: AQI, Al Qaeda in the Islamic Maghreb, AQAP, and al-Shabaab.
However, bin Laden’s focus on unity was not limited to bringing groups under Al Qaeda’s auspices.135

Seeing first-hand how a lack of unity could waste a victory cemented his prioritization of uniting jihadists in the campaign against the United States.

Under his leadership, Al Qaeda constantly urged unity among the Sunni groups in Iraq as a religious necessity and a strategic requirement. In promoting the religious obligation to unite, bin Laden repeatedly drew from examples in Islam’s history.

Al Qaeda’s handling of the strife between ISI and Ansar al-Islam (aka Ansar al-Sunna) reflected bin Laden’s conviction that unity was paramount. Despite serious accusations from Ansar al-Islam about ISI’s conduct, Al Qaeda repeatedly pressured its Kurdish ally to unite with ISI. Al Qaeda’s insistence on unity is even more telling because Al Qaeda’s relationship with Ansar al-Islam predated its alliance with AQI. Al Qaeda held Ansar al-Islam in high esteem, writing that “our honorable Shaykh [bin Laden] and the Mujahidin brothers here have great respect and appreciation for the Army of Ansar al-Sunnah [Ansar al-Islam], and they consider them and us one item.”142

A ruling from him that endorsed division would have been unprecedented and inconsistent with his relentless promotion of unity.
Second, al-Zawahiri’s ruling was inconsistent with bin Laden’s views because al-Zawahiri adhered to the “artificial” borders imposed by the Sykes-Picot agreement, a deficit that al-Baghdadi also used to delegitimize al-Zawahiri’s ruling. Bin Laden had repeatedly declared his opposition to these borders. As Coll explained, “He rejected the borders of many nation-states as illegitimate lines drawn by pagan colonialists.”150

Consequently, he assigned Al Qaeda’s affiliates regional responsibilities that abdicated the existing national boundaries. For example, Al Qaeda in the Islamic Maghreb’s purview expanded from Libya to Mauritania, while al-Shabaab had authority over the Horn of Africa.151

Also, Al Qaeda anointed al-Zarqawi’s group as Al Qaeda in the Land of Two Rivers/Al Qaeda in Mesopotamia instead of just Al Qaeda in Iraq, which could be interpreted to include Iraq and some parts of Syria as well as Iran and Turkey. Al Qaeda’s decision, or at least concurrence with ISI’s decision, to send personnel into Syria suggests that it agreed that Syria fell under the group’s mandate. Either way, al-Zawahiri’s adherence to national boundaries in his edict ran counter to bin Laden’s abdication of these boundaries.
Taken together, bin Laden’s commitment to unifying jihadist forces and rejection of national boundaries strongly suggests that he would not have ordered a split between al Nusra and ISIS. This does not necessarily mean that he would have accepted ISIS’s power play either, more likely seeking a compromise that ensured unity and local leadership in the insurgencies. Moreover, his rejection of the current national boundaries makes it difficult to fathom that he would use them to delineate responsibility between two Al Qaeda allies.
Bin Laden versus Al-Zawahiri: A Leadership Comparison
The first question that arises when assessing whether leadership was a factor in the Al Qaeda and ISIS dispute is: what was bin Laden’s role in interactions with the affiliates? Admittedly, Al Qaeda did not rely solely on bin Laden to keep the affiliates in line. As exemplified by Shapiro’s “terrorist dilemma,” due to the dangers posed by counterterror initiatives, leaders must often sacrifice operational control to retain operational security.152
152. Jacob N. Shapiro, The Terrorist’s Dilemma: Managing Violent Covert Organizations(Princeton, NJ: Princeton University Press, 2013), chap. 1.View all notes
As a result, bin Laden’s deputies, particularly al-Zawahiri, Atiyah Abd al-Rahman, and Abu Yahya al-Libi, undertook much of the communication with the affiliates, conveying Al Qaeda’s guidance, counsel, and policies as well as sometimes seeking assistance.153
153. Abu Yahya al-Libi’s death in 2012 and Atiyah Abd al-Rahman’s death in 2011—both respected Al Qaeda theologians—also harmed al-Zawahiri’s ability to manage the dispute with ISIS. Bin Laden would also have struggled without their counsel, but was still far more able than al-Zawahiri to manage the conflict. We thank the anonymous reviewer for this point.View all notes
However, behind the scenes, bin Laden was extensively involved as well, seeking updates and issuing guidance to send to the affiliates through his deputies.154
154. At times his deputies felt bin Laden was too involved. See Scott-Clark and Levy, The Exile, p. 351.View all notes
Bin Laden would also communicate to his deputies whether he approved of how they dealt with situations. For example, he chastised al-Zawahiri for making public Al Qaeda’s frustrations with al-Zarqawi, saying that such matters should be handled privately.155
155. Scott-Clark and Levy, The Exile, p. 243.View all notes
Given the security concerns, bin Laden sometimes could not be involved to the degree that he would have liked; he was, as Bergen and Cruikshank argued, a “hands-on leader.”156

Nonetheless, when it came to major issues with the affiliates, bin Laden was consistently involved and his decisions were the final word. This was increasingly the case as trusted members of bin Laden’s shura council were captured or killed,157
157. The Long War Journal reports that the U.S. drone strike campaign in Pakistan alone killed over fifty senior Al Qaeda members between 2004 and 2010. Several members of the Al Qaeda shura council, or individuals that are otherwise identified as having close relations with bin Laden, were either killed or captured in the decade leading up to bin Laden’s death, such as: Abu Hafs al-Masri (killed November 2001), Muhammad Atef (killed November 2001), Abu Mohammed al-Masri (detained in Iran from around 2003–2015), Saif Al-Adel (detained in Iran from around 2003–2015), Sayeed al-Masri (killed May 2010), and Abu al-Khayr al-Masri (detained around 2003–2015).

and replaced with senior leaders with whom he was less likely to consult.
An insightful illustration of bin Laden’s role vis-à-vis the affiliates occurred when Al Qaeda decided to make al-Shabaab an affiliate. Initially, one of the major components of the affiliate alliance was that the subordinate group publicly adopted Al Qaeda’s name. However, bin Laden grew concerned about the Al Qaeda name, even contemplating changing it.158
158. SOCOM-2012-0000009, Undated, Harmony Database, Combating Terrorism Center at West Point. Available at https://www.ctc.usma.edu/posts/letters-from-abbottabad-bin-ladin-sidelined (accessed September 15, 2017).View all notes
Then, in 2010, when bin Laden was deciding whether to make al-Shabaab an affiliate, the issue of whether to make the relationship public was a point of contention. Bin Laden decided that al-Shabaab should become an affiliate, but unlike previous arrangements, there would be no name change and the affiliation would be private; neither group would publicly announce or tout it. He wrote:
Now, in relation to the issue of unity, I see that this obligation should be carried out legitimately and through unannounced secret messaging, by spreading this matter among the people of Somalia, without any official declaration by any officers on our side or your side, that the unity has taken place.159
159. “SOCOM-2012-0000005,” p. 1.View all notes
Al-Zawahiri urged bin Laden to reconsider his decision to keep al-Shabaab’s affiliation private, to no avail. While bin Laden told al-Shabaab that the reasons for private affiliation were to avoid increased counterterrorism pressure and keep funding avenues open for al-Shabaab, al-Zawahiri feared that bin Laden was heeding the concerns of some who worried Al Qaeda was “inflating its size and growth.” He urged bin Laden t reconsider his “opinion not to declare the accession of the brothers of Somalia.”

Nonetheless, al-Shabaab remained a private affiliate until after bin Laden’s death, when al-Zawahiri announced al-Shabaab as an affiliate in February 2012. While there was no public announcement, in the interim, Al Qaeda took the need to support al-Shabaab seriously, providing guidance and input on how it should govern, its attacks and targets, economic opportunities, and religious counsel, as it did with other affiliates.

Thus, while bin Laden solicited and accepted input from others, he made the final decision on such matters.
This leads to a related and equally important second question: would bin Laden have handled the dispute with ISIS more effectively than al-Zawahiri and thus forestalled an alliance rupture? To assess this question, it is critical to first identify what qualities are conducive to alliance management, particularly when conflict arises. First, given that the dispute between al Nusra and ISIS involved two powerful entities with ambitious leaders, the Al Qaeda leader had to be sufficiently credible and respected that his ruling would be accepted or, at a minimum, not publicly rejected. Second, given that tensions were running high between Al Qaeda’s allies, the Al Qaeda leader needed to be diplomatic and capable of defusing tensions. Third, given that both groups were convinced of their positions, the Al Qaeda leader had to be able to persuasively justify his position to both sides and skillfully articulate that position.
Based on these criteria, al-Zawahiri’s relative shortfalls are quickly apparent, particularly in his inability to command the respect of al-Baghdadi and al-Jolani. Bin Laden possessed a unique combination of characteristics that had earned him the respect of fellow jihadists for decades. As Byman explained, bin Laden was a “charismatic yet humble man who did not demand adulation but inspired those around him; an ideal combination for unifying a movement.”

He enjoyed considerable prestige, which bordered on mythic status, derived from his ability to confront superpowers—from the Battle of Jaji against Soviet forces in Afghanistan to 9/11—and survive against long odds, thereby perpetuating the notion that he received divine help.

Bin Laden’s ability to maintain legitimacy and credibility in the movement for over two decades was partially derived from the way he presented himself: as a man who sacrificed everything for Islam. He built the legend of a “rich man who live[d] like the poor, a socially advantaged man who was prepared to sacrifice everything for his religion, a fighter who would not waver in the face of death.”166

Qamar’s words would prove prescient as the path that led al-Zawahiri to become bin Laden’s deputy was littered with leadership failures. Scheuer summed it up saying:
Zawahiri was inept at running the EIJ’s [al-Jihad] international cells, and his mistakes allowed Egyptian intelligence to wreck the network—forcing al-Zawahiri to seek out bin Laden’s aid and accept his direction. Al-Zawahiri and his lieutenants completely failed to damage the Egyptian government—and so accepted bin Laden’s plan to knock the U.S. props from under Mubarak’s regime. … Al-Zawahiri was unable to raise any significant amount of money and was all but broke—and so was forced to begin working with bin Laden.175

At the helm of al-Jihad and then Al Qaeda, more charismatic rivals with religious credentials repeatedly overshadowed al-Zawahiri. As would occur in 2013 with al-Baghdadi, in the 1980s and 1990s, al-Zawahiri struggled because he lacked the charisma, celebrity, or credentials of rivals including bin Laden’s mentor Abdullah Azzam or al-Gama Islamiyah’s spiritual leader, the Blind Sheikh.
Moreover, as the leader of al-Jihad, al-Zawahiri led his group from disaster to failure. The group’s first two attacks failed to kill the targeted Egyptian officials.

Even the group’s most successful attack—a suicide truck bomb attack against the Egyptian embassy in Islamabad in 1995—caused dissension. This attack endangered a sanctuary for jihadistsand the main route into Afghanistan. Also, within al-Jihad, some expressed disquiet about targeting civilians in the embassy and the use of suicide operations. Such internal turmoil prompted al-Zawahiri to issue a statement the following year that defended the attack against the Egyptian embassy in Islamabad by pointing to the Embassy’s activities against al-Jihad, the recent extradition agreement between the two countries, and Islamabad’s persecution of the mujahidin.177

Second, to effectively handle the al Nusra and ISI conflict, the Al Qaeda leader needed to have the ability to defuse tensions. Bin Laden consistently demonstrated an ability to manage tensions with his humble style, while al-Zawahiri repeatedly exacerbated conflict with his dictatorial manner. Bin Laden held “himself above the fray” of the infighting that plagued the Sunni jihadist movement and strove to prevent and address disagreements among jihadists in a calm manner.

While bin Laden grappled with a fair share of divergent views and disagreements, it is telling that Al Qaeda did not experience a major splinter of consequence under his leadership, a rarity among terrorist organizations, which speaks to bin Laden’s diplomatic prowess.
Not only would these characteristics have helped bin Laden reduce the tensions between al Nusra and ISIS, his approach would have served him well if ISIS pushed back on his ruling. Except for his avowed enemies, bin Laden consistently avoided attacking or repudiating those who denounced him. He did not disavow his family, friends, or even the Sudanese regime, which bilked him for significant investments and betrayed him.181

Thus, he was unlikely to over-react to ISIS’s discontent or “fire ISIS for its public defiance” as al-Zawahiri did.
Moreover, bin Laden rarely experienced acrimonious breaks with those he disagreed with because of his ability to manage dissent.

Similarly, al-Jihad and al-Gam’a Islamiyah, a rival Egyptian Salafist jihadist organization that also sought the overthrow of the Egyptian regime during the 1990s, repeatedly failed to overcome their differences and unite in pursuit of their common cause. While the blame does not lie solely with al-Zawahiri, he exacerbated al-Jihad and al-Gama’a Islamiyah’s rivalry. Although his colleagues urged him to moderate his discourse, al-Zawahiri wrote a lengthy treatise rejecting al-Gama’s spiritual leader, the Blind Sheikh, as unfit to lead because of his blindness, paving the way for their future inability to work together.

Consequently, when al-Gama’a Islamiyah declared a ceasefire in the late 1990s, al-Zawahiri could not dissuade the group, despite his repeated attempts.

Once again, al-Zawahiri was the source of tensions, rather than someone who mitigated them.
Al-Zawahiri’s tendency to cause conflict was not limited to external rivals, as he compounded al-Jihad’s internal dissension in the 1990s. He undertook actions by fiat—without consulting al-Jihad’s leadership shura—such as signing onto bin Laden’s 1998 International Front Against Jews and Crusaders, which committed his organization to pursing a different cause than the one that animated most members.194

Al-Zawahiri escalated conflicts, while bin Laden sought to defuse them.
Justification for his Position
Finally, to manage the al Nusra and ISIS conflict, the Al Qaeda leader had to offer a justification for his position that would skillfully articulate his position and persuade both sides. Al-Zawahiri’s ruling was woefully inadequate on this score. He offered no explanation or justification for his instructions that al Nusra should act as Al Qaeda’s representative in Syria, while ISIS must return to operating only in Iraq. He both praised and chastised the groups and then issued a ruling without explaining the basis of it. Once again, he expected his orders to be followed simply because he issued them.
Bin Laden’s writings, particularly those that offer recommendations or instructions to others, are replete with religious explanations and analogies to justify his positions.204
204. See for example his emphasis on the need to use “Shari’a evidence and logical assessment” to persuade allies of a controversial position in Letter Addressed to Atiyah, p. 3.View all notes
Bin Laden’s use of scripture, history, and the Sunnah gave his opinions credibility and insulated him from being summarily dismissed, as occurred with al-Zawahiri. Yet, bin Laden was not a religious scholar nor did he claim to be one, claiming, as Scheuer recounted, “only to be a ‘humble slave of God’ forced to into this role because the Islamic world’s ‘illustrious scholars’ have been silenced.”

In addition, because of his lack of formal religious credentials, he sought input from the religious scholars within Al Qaeda in order to make decisions, which he publically acknowledged when he said, “My job is not to lead but to follow. … I always seek guidance from many great religious scholars.”207
207. As cited in Scheuer, Osama bin Laden, p. 164.View all notes
When bin Laden’s decisions did not provide a religious justification, he offered political rationales for his decisions, usually framing them in terms of the best interest of others. For example, when he opted to maintain a private alliance with al-Shabaab, he justified doing so by saying that this would protect al-Shabaab from counterterrorism pressure and allow it to more readily attract funds from the Gulf.208

However, this comparative counterfactual analysis suggests that not only would bin Laden have viewed the conflict between al Nusra and ISIS differently than al-Zawahiri, he would have been more capable at managing the dispute and hard feelings stemming from it. In other words, the alliance was troubled, but not doomed. The change in Al Qaeda’s leadership was key to the alliance outcome.
Implications and Recommendations
The findings in this article suggest the need for a careful evaluation of the targeted leader and his or her likely successor. By employing counterfactuals to examine the strength of individual and systemic explanations for the split between Al Qaeda and ISIS, the article concludes that individual leaders can factor greatly into outcomes of seminal events. The systemic explanation of the split—that Al Qaeda and ISIS would have inevitably experienced the break because of irreconcilable differences in 2013—possesses some weaknesses. Despite the numerous problems cited in the strategic explanation for the split—including divergent views on acceptable levels of violence, disparate priorities, lack of consultation, and intractable leaders in 2013—Al Qaeda had encountered these challenges in the preceding decade and maintained the alliance with its partner in Iraq nonetheless.
On the other hand, the first image explanation offers a much more compelling argument for the Al Qaeda–ISIS split. Whether bin Laden or al-Zawahiri, the leader of Al Qaeda shaped the group’s priorities, preferences, and credibility in the eyes of Al Qaeda’s allies. Also, Al Qaeda’s leader impacted the group’s diplomatic strategies and persuasiveness when offering unwelcome rulings to an ally. In short, the capabilities of Al Qaeda’s leader determined the group’s ability to prevent the alliance rupture.
Although the findings highlight the importance of terrorist leaders, they neither prescribe nor proscribe leadership decapitation. Instead, they suggest the need for a careful evaluation of the targeted leader and his likely successor. States must weigh the advantages and disadvantages of leadership decapitation against a particular terrorist group before they commit to the practice. As the article explored, the elimination of bin Laden promoted a deputy less capable of managing the group’s alliances, exacerbated the Al Qaeda–ISIS fissure, and weakened Al Qaeda in several veins. However, the same example displays how the splintering of terrorist alliances can also prompt adverse and unforeseen consequences, as evidenced by the subsequent surge of ISIS.
Since leadership decapitation remains an essential component of U.S. counterterrorism policy against ISIS and other terrorist groups, this study contains multiple implications for scholars and policymakers alike.
First, individuals matter, and terrorist leaders’ impact on a group’s ability to manage its alliances should not be ignored in terrorism scholarship and counterterrorism policymaking. As demonstrated through the counterfactual analysis of the Al Qaeda–ISIS split, terrorist leaders shape their groups’ priorities, preferences, and credibility in the eyes of allies. In other words, the qualities of terrorist leaders can determine the group’s goals, strategies, and ability to manage alliances.
Second, counterfactual analysis has value for developing counterterrorism strategy. Counterfactual analysis offers a useful heuristic for reviewing past policy decisions. For instance, the examination of counterfactual trajectories had bin Laden survived enabled the ability to determine which course of events proved most devastating to the group’s ability to maintain alliances. Likewise, counterfactual analysis offers a creative tool to examine policies authorized against Abu Bakr al-Baghdadi and ISIS (and other terrorist organizations). Just as the employment of counterfactuals helped determine the decisive variable maintaining Al Qaeda’s alliances, intelligence analysts or military strategists could employ counterfactual analysis to determine the decisive variables enabling ISIS’s success in various respects. In other words, counterfactual analysis could help policymakers isolate the most effective policy to implement against a terrorist group.
Third, leadership decapitation can exacerbate fissures within a terrorist organization and drive allies apart. Of course, one cannot confidently say that the United States is “better off” due to the Al Qaeda–ISIS split or that the alliance would not have ended at some subsequent juncture. Nonetheless, the juxtaposition of al-Zawahiri and bin Laden demonstrates how the ascension of a less capable leader can accelerate the fracturing of a terrorist alliance. These fractures can diminish a group’s operational reach and harm a group’s image in the eyes of potential recruits and other allies.
Fourth, assessing the utility of leadership decapitation in any case requires an examination of the current leader’s capabilities relative to the capabilities of the likely successor. Many studies of leadership decapitation tend to focus on the idiosyncrasies and capabilities of the targeted leader to determine the method’s effectiveness. However, comparing the qualities of the leader to that of the deputy creates the capability to determine how decapitation will impact a group. For example, one would not grasp how bin Laden’s death impacted Al Qaeda’s ability to manage its alliance with ISIS without the juxtaposition of bin Laden and al-Zawahiri’s respective priorities, preferences, perceived credibility, and ability to handle conflict.
Fifth, the study problematizes the critique of leadership decapitation that a more dangerous or radical leader might rise to fill the void left by the decapitated leader. While the likely successor is sometimes not clear to intelligence officials, in high priority groups—the very organizations most likely to be considered for leadership decapitation—analysts often can narrow the options down to a few likely options. Also, the study demonstrates that policymakers, analysts, and academics can discern the interests and preferences that will shape the decision making of that successor as well as his or her competence in handling disputes. Of course, a terrorist leader’s deputy may indeed be more radical than the leader himself or herself. However, the analysis of al-Zawahiri’s tendencies based on his previous leadership of al-Jihad demonstrates how analysts could determine the predispositions of likely successors well before decapitation occurs.
Even though leadership targeting remains a cornerstone for U.S. counterterrorism strategy, some diminish or outright ignore the role of first image theorizing in terrorism scholarship and counterterrorism decision making. This article has illustrated a previously underdeveloped method for analyzing the efficacy of leadership decapitation. Future research in terrorist decapitation needs to examine not only the effects of removing that specific leader, but the quality and effectiveness of the next possible leader(s). As a result, this article recommends future scholarship that employs counterfactual analysis of a decapitated group other than Al Qaeda in order to draw comparisons between the leadership styles of the previous and successive leaders.
