Many Democrats (and some Republicans) are calling for pulling out U.S. troops from Iraq. But the obvious question then arises: Can we really just leave and risk the civil war (if it is that) getting worse?
I'm very surprised that I haven't heard more support for the following idea for dealing with the aftermath of a pull out: Having an international coalition of troops step in. Sure, it would be hard to generate support, but I don't think it would necessarily be impossible. If the next U.S. President would stand up and say, "We made a mistake in invading Iraq, and now we need the world's help to mitigate the damage," it might be possible. No one wants to see the Iraq turmoil get worse and spread. This could be a way to prevent that.
The other alternative, of course, is to stay there for the indefinite future, incurring more casualties and watching the violence get worse.
