So let's assume for a second Ms. Sheehan is successful in her efforts to convince Bush into an immediate pull out of US forces from Iraq, what happens to the Iraqi people then? Ignore the justification argument about the death of over 1800 US men and women in the region and that whole line of argument about justifying their death, it's not one that holds much water as a reason to stay the course in Iraq.
But the ordinary men, and women of Iraq who voted in elections, are trying to fashion a constitution in the face of sectarian, tribal, religious and burning desire for "payback" over the murders and real suffering under Sadam's regime, what happens to them? We the United States have managed to tear apart the working social order in Iraq, horrible as it was, and replace it with what, a half baked idea called Democracy that the US is leaving the Iraqi people to finish. The Iraqi people seem to like the idea of Democracy by the way, but it's a rather strange dish for them and they seem have not quite got the hang of it. On the other hand, there are lots of hard core Muslim fundamentalist in the region who do not like the whole idea of democracy. They like their women repressed, they like the rule of their view of god's authority over mankind in all things, in short they hate democracy.
I think it was Colin Powell that warned, "You break it, and you own it". Well we broke it and we own it, or do we morally owe anything to the people of Iraq when balanced off against the desire to leave now and stop any further deaths of our troops?
It's not a pretty choice, but there it is.
