I hear you. The main reason I oppose this war has to do with what you've laid out: What would a post-Saddam Iraq look like? If this were a global effort to oust a potentially dangerous and destabilizing dictator and replace him with a multiethnic democracy, who here wouldn't sign on? (Well, I have some guesses . . .) But given the region and realpolitick, I cannot see anything but another Sunni regime keeping the Kurds and Shias in check, only this one would be beholden to Washington, much more so than Saddam ever was, and its use of force would be limited.
Then there's the oil angle, and I highly doubt that the Bush/Cheney Co. is interested in the democratic allocation of crude.
The only good thing one can say about US intervention in Iraq right now is the protection of the Kurds, who are, as we've seen, blossoming in a way unimaginable if Saddam were left alone. And that's really the question for the "antiwar" crowd: What is your solution? If you say US out of Iraq and End the Sanctions, then what becomes of the Kurds? And what about Saddam's quest for the bomb? Would you feel safer with a nuclear Iraq? Isn't it bad enough that Pakistan is armed?
So, we can jeer Bush till our throats give out, and it feels good, I know. But this situation, in addition to the al-Qaeda factor, is a little more complicated than just "No Blood for Oil!"
