Beware The Ides Of March

Zizka is back and asks the logical question:

What do we do when the war starts? He has a list of possibilities, beginning with the obvious call to arms for regime change at home.

Matt Yglesias has also brought this up a number of times, particularly as it pertains to the anti-war movement shifting its emphasis from stopping the war to re-building Iraq properly.

I have been convinced that the war would happen since last August, barring a miraculous spine transplant from the Democrats or the UK bowing out. Since neither of those things have happened, we're going, (supposedly on the 17th, although just because this group is so incredibly predictable, it will probably be on the 15th. Hail Caesar.)

Leap-frogging over the horrible carnage we are about to wreak but over which we so clearly have no say, I ask all 12 of my readers to weigh in on this because I'd really like to know. Taking all of Zizka's points into account, how can we also persuade the Bush administration to deal with post-war Iraq properly?
