I was traveling yesterday during the big news: With the aid of cellphone surveillance and an Al Qaeda informer who suggested tracking “spiritual adviser” Sheikh Abd al-Rahman, the US military dropped two 500-lb bombs on Abu Musab al-Zarqawi, the leading Iraq insurgent (and Al Qaeda poster boy for the administration.) Undoubtedly good news for our efforts in Iraq (and, lord knows, Dubya needed some good news in the worst way, particularly in the wake of Haditha.) Still, this big kill obviously doesn’t answer the big questions about Iraq’s stability, or our continued involvement in the region: “‘The immediate aftermath of this will probably be an upsurge of violence’ as Sunni insurgents hurry to show that Zarqawi’s killing has not broken the resistance, said Michael Clarke, an expert on terrorism at the International Policy Institute of King’s College London. ‘In the medium term, in the next month or two, it will probably help to downgrade sectarianism,’ Clarke said by telephone. ‘But the dynamic of sectarian violence is probably past the point of no return.’” And, of course, while this strike will hopefully be a stunning blow to Al Qaeda in Iraq, what of the original Al Qaeda in Afghanistan and around the world? We’re nearing five years since 9/11, and Osama’s still out there…
