Al Qaeda and its rogue stepchild, the Islamic State, are locked in mortal combat. The two are now competing for more than the leadership of the jihadist movement—they are competing for its soul.
ALMOST OVERNIGHT, the Islamic State sent its enemies reeling—and turned U.S. policy in the Middle East upside down. Islamic State forces carved out a haven in Syria and, in June 2014, routed the Iraqi army, capturing large swathes of territory and prompting the Obama administration to overcome its long-standing aversion to a bigger U.S. military role in Iraq and Syria. Even in many Arab countries where the Islamic State does not have a strong presence, its rise is radicalizing those countries’ populations, fomenting sectarianism and making a bad region even worse.
But there is one person for whom the Islamic State’s rise is even more frightening: Ayman al-Zawahiri. Although the Al Qaeda leader might be expected to rejoice at the emergence of a strong jihadist group that delights in beheading Americans (among other horrors), in reality the Islamic State’s rise risks Al Qaeda’s demise. When Islamic State leader Abu Bakr al-Baghdadi rejected Al Qaeda’s authority and later declared a caliphate, he split the fractious jihadist movement. The two are now competing for more than the leadership of the jihadist movement: they are competing for its soul.
Who will emerge triumphant is not clear. However, the implications of one side’s victory or of continuing division are profound for the Middle East and for the United States, shaping the likely targets of the jihadist movement, its ability to achieve its goals and the overall stability of the Middle East. The United States can exploit this split, both to decrease the threat and to weaken the movement as a whole. Washington must also adjust its counterterrorism policies to recognize the implications of this rivalry.
