As many as 15,000 foreign volunteers have swelled the ranks of rebel and jihadist formations currently fighting in Syria, according to the most recent United Nations report.
Most come from neighboring Arab countries, but more than 2,000 have arrived from a handful of European countries, with smaller numbers coming from Australia and North America.
Their presence in Syria and Iraq increases the available reservoir of Western passports and “clean skins” that terrorist planners could recruit to carry out terrorist missions against the West. And what happens when they return — more radicalized, more experienced, determined to continue their violent campaigns at home?
Thus far, homegrown terrorist plots in the United States have been remarkably amateurish, although at times still lethal. The existing pool of determined jihadists in America is very small and lacks training and experience, which fighting in Syria and Iraq would provide. Returning jihadi veterans would be more formidable adversaries. Still, the threat appears manageable using current U.S. laws and existing resources.
Concern that al Qaeda’s affiliates in Syria and the Islamic State in Iraq and Syria (ISIS) would inevitably employ their foreign fighters to launch terrorist operations against U.S. targets or in the United States was one of the principal reasons given for initiating American military action in Iraq and Syria. But the American bombing campaign now also gives a motive for ISIS to counterattack.
Of greatest concern is a scenario in which Western volunteers who initially went to fight in Syria or Iraq are recruited, trained and supported for terrorist operations in the West. Determined to pursue its strategy of attacking the “far enemy,” al Qaeda’s central command deployed the Khorasan group, a cell of seasoned jihadist veterans from Afghanistan and Pakistan, to Syria to recruit and equip suitable Westerners for terrorist attacks outside the region. The first U.S. bombings in Syria targeted the Khorasan group.
U.S. government sources report that more than 100 Americans have attempted to go or have gone to Syria to join the various rebel formations — in particular, al Qaeda’s affiliate Jabhat al-Nusra or ISIS. Twenty of these volunteers have been publicly identified as a consequence of arrests and prosecutions in the United States or as a result of their deaths in Syria, some as suicide bombers.
It is too few to draw a reliable group portrait of this particular cohort of American jihadists. However, at least 124 Americans have gone or have attempted to go abroad to join jihadist fronts in Afghanistan, Pakistan, Somalia, Yemen and more recently, Syria.
Forty-one of these would-be jihadis were arrested before they left the United States and 24 were killed while abroad — six in suicide bombings, two as a result of American airstrikes and two as a consequence of internal disputes within the terrorist groups. The cause of the other deaths is unknown. Thirteen more were arrested while abroad, three of whom were extradited and prosecuted in the United States. Thirteen are still at large. Of those known to have returned to the United States, 32 were arrested and one was killed.
Thirty-seven went or tried to go to Pakistan; 34 went or tried to go to Somalia; 20 to Syria; 18 to Afghanistan; and 11 to Yemen. The remainder went to other countries. Forty-two wanted to join al Qaeda or one of its affiliates, 34 wanted to join al Shabab, and eight joined or wanted to join Lashkar-e-Taiba. Twelve intended to join ISIS, four wanted to join Jabhat al-Nusra or other al Qaeda in Syria, and another four sought the Taliban. Some were ready to join any jihadist group.
Their motives for going abroad are diverse and include religious fervor, jihadist ideology, a determination to defend Islam against infidel aggression, wanting to participate in an epic struggle, a thirst for adventure or the desire to prove oneself as a warrior. Some of those initially going to Syria went in response to the Syrian government’s brutal campaign against the rebellion, but as the nature of the armed resistance changed, jihadist ideology and ISIS’s highly publicized extreme violence became the principal recruiting appeal.
The evidence is still sketchy, but there are indications that joining jihad may transcend its religious and ideological precepts and slide into popular culture as an expression of broader rejection of today’s society and resistance to the existing establishment.
