The occupation of Iraq is, regardless of your position, the stupidest thing this country has ever done. We need to either do it right or get out, all the way out.
To occupy Iraq correctly entails implementing Soviet- or Nazi-style oppression. (You can call it "Roman-style" if you want to avoid uncomfortable historical analogies.) Alternatively, we can just kill most of the Iraqis and just settle the country ourselves.
I don't want to do either, so the only option acceptable to me is to get all the way out.
It's the Republicans' job to convince us to do the job right. They can, if they choose. A country that has countenanced the genocide of the American Indians, the internment of tens of thousands of actual citizens in WWII, the conquest of the Philippines, and centuries of slavery can be convinced to occupy or sterilize Iraq.
It's the Democrats' job, therefore, to get us out. Forget "change"; forget transforming our society; forget health care, the financial crisis, or the size of Barack's penis or Hillary's breasts. This is a no-brainer: if the Democrats cannot get us all the way out of Iraq, they are completely useless.
I'm going to vote Democratic one last time. But, if the Democrats do not end the occupation of Iraq by November 2010, I am never voting Democratic again for the rest of my life. I'll change my affiliation and destroy my altar to Walter Mondale. If they get their shit together after 2010, well, too bad for them. I'll wish them the best, but they can go on without me.
Everything else is open to negotiation and compromise. But if they can't do this one simple, rational thing; if they can't reverse a not only completely immoral and heinous but also obviously stupid half-assed occupation, they are worthless.
