If the Iraqi prime minister thinks we should go, we should go. If McCain has any sense (admittedly, not something in evidence so far in his campaign’s response to the Maliki remarks), he’ll pivot to underbid Obama, Name That Tune style: “16 months? I’ll do it in 8!”
Mind you, I’ve already predicted that the net effect, blogospheric bloviation aside, of McCain and Obama’s positions on leaving Iraq on the actual date of departure is on the order of milliseconds, so I really don’t care that much what domestic political games the Iraqi government wants to play to shore up Sunni-Shiite cooperation in parliament.
