Insurgents detonated bombs inside one of Iraq's holiest Shiite shrines Wednesday, destroying its golden dome and triggering more than 60 reprisal attacks on Sunni mosques. The president warned that extremists were pushing the country toward civil war, as many Shiites lashed out at the United States as partly to blame.Swopa rounds up evidence—okay, more like the barest of hints—that the Samarra bombing could have been the work of militant Shiites looking to provoke some serious sectarian warfare. It's not impossible, I guess. Quite obviously a lot of different groups in Iraq have a lot of different motives for edging the country closer to civil war, and it's getting easier and easier by the day. But it seems more likely that, as Swopa says, al-Qaeda in Iraq did this, in order to keep "Iraqi Sunnis out of nonviolent politics by pushing the Shiites further against the wall."
