By the way, putting aside all the histrionics, it may well be necessary to effect a partition (which is sort of what you are saying, albeit with the Sunni's have relatively few zip codes left, and very many to most of them causing trouble elsewhere, angry and hateful of the US, and ready for more, via Syria or whatever), if things go wrong with the current policy, which they may well, but it should be done while minimizing the sanguinary, not maximizing it. That would be moral.
Partition doesn't solve the problem.
Kurdistan is already effectively autonomous, and largely peaceful.
The rest of Iraq is in a civil war, and Sunnis are concentrated in Baghdad as well as Anbar Province, in the West.
You could partition Anbar off (although NOBODY will accept that: the Shi'ites hate their Sunni former tormentors, and even the Kurds aren't willing to just let the Ba'athists who gassed them go. No, those people need to die.), but you can't partition Baghdad itself. That's where the death squads are, and will remain, until we firmly take one side and drive the other out.
But you needn't worry too much.
We won't do that.
The President has been given the advice I am repeating here.
He's been given it at least three times. He firmly rejects it on the same grounds you do: immorality. He thinks it's immoral to take sides and doom the Sunni Arabs to subjugation and death.
So we're not going to do it.
We're going to follow Bush's strategy to the bitter end.
The Clinton/Obama team will order the general pullout.
