What Government

I know these guys are always posturing, but somehow this has a more genuine feel to it:

In an interview with Nic Robertson of CNN, Iraq's Sunni Arab vice president, Tariq al-Hashimi, has laid down an ultimatum. He said that he would pull the Iraqi Accord Front (Sunni fundamentalists) out of the al-Maliki "national unity" government if [Shiite] militias are not disarmed and revisions to the constitution aren't begun by May 15. He said he was ready to admit that he had "made the mistake of a lifetime" in agreeing to participate in the government if no progress were made by that date on these issues.

Sadr and his deputies have already abandoned al Maliki. The further loss of these MP's would seem to indicate that Maliki's government would then be toast. I suspect, at best, Maliki can make some window-dressing type concessions, but there's no way he'll abandon his support of the Shiite militia's. At best the infighting continues. At worst, the government collapses.
