It is the proposition of those critical of American and British military efforts in Iraq, that we ought to withdraw our troops and abandon the Shi'ites to the mercies of the Sunnis yet again. And they propose this from a position of purportedly superior moral rectitude. Whether or not one thinks highly of George W. Bush, to the extent that he is conducting this war to rectify a monstrous wrong perpetrated by his father, he is a man struggling to do the right thing. He has more or less sacrificed his one chance at being anyone of consequence in the world, his having stumbled into the American presidency, to the task.
We owe it to the Iraqi people to make good on the promises Bush Senior made to them - safety from Sunni-Ba'ath violence and domination. If that means that Iraq will be transformed into a loose confederation like Switzerland or Canada, so be it - there are worse fates.
