BERNARD HAYKEL cree que al-Qaeda está perdiendo:

WHEN Iraq's most notorious terrorist, Abu Musab al-Zarqawi, declared a "full-scale war" on Iraq's Shiites on Sept. 14, he appeared to be speaking for all or most jihadis. But Mr. Zarqawi's war on Shiites is deeply unpopular in some quarters of his own movement. In fact, growing splits among jihadis are beginning to undermine the theological and legal justifications for suicide bombing. And as that emerging schism takes its toll on the jihadi movement, it could well present an opportunity for Western governments to combat jihadism itself.

The simple fact is that many jihadis believe the war in Iraq is not going well. Too many Muslims are being killed. Images of that slaughter, conveyed by satellite television and the Internet throughout the Muslim world, are eroding global support for the jihadi cause. There are strong indications from jihadi Web sites and online journals, confirmed by conversations I have had while doing research among Salafis, or scriptural literalists, that the suicide attacks are turning many Muslims against the jihadis altogether.

The movement's leadership is sensitive to Muslim public opinion. Mr. Zarqawi's mentor, Abu Mohammed al-Maqdisi, has denounced the campaign against Shiites as un-Islamic. Other prominent radical Islamists have advanced similar criticisms. And in a letter made public last week, Al Qaeda's second in command, Ayman al-Zawahiri, cautioned Mr. Zarqawi against particularly gruesome executions and attacks on Iraqi civilians for fear of their negative impact on the global jihadi cause.

To be sure, the alternatives these critics recommend are no less violent. Rather, many of the movement's dissidents suggest that jihadis diminish their efforts in Iraq and revert to spectacular attacks in the West, like those that took place on Sept. 11. These, such thinkers maintain, are singularly popular among Muslims and the only effective means of doing long-term damage to the West.

Still, Western governments should encourage the debate among jihadis because, if the promise of absolute salvation through suicide attacks is thrown into question by some within the jihadi movement, potential recruits may come to doubt the wisdom of engaging in such tactics.
