Fear and Trembling

From Joe Klein:

[Attacking Moqtada al-Sadr] would have been extremely foolish. The U.S. would have been inserting itself into a part of Iraq that we don't know very well—the south—and taking sides against what is probably the most popular mass movement in Shi'ite Iraq. But the Petraeus battle plan apparently includes an anti-Sadrist move, which may mean a spurt of violence as widespread and vicious as the worst of the Sunni insurgency. Is that why the general wants a "pause" in the U.S. withdrawal this summer?

What could possibly be the rationale for this? Perhaps it is that Sadr's Mahdi Army is the most potent force opposed to long-term U.S. bases in Iraq—and that a permanent presence has been the Bush Administration's true goal in this war. I suspect the central question in Iraq now is not whether things will get better but whether the drive for a long-term, neocolonialist presence will make the situation irretrievably worse.
