It wouldn't be "facilitating the return", it would be leaving. We put our troops in Kuwait, you think a Baathist is going to take over and start flipping us the finger? No way. He'd be a dead man. And I'd take a secular Baathist strongman who was neutral on America before an Islamist theocracy. Wouldn't you?
The terrorists in Iraq, are foreign nationals and Hussein's old crew. Why are you interested in facilitating their rise to power. I'm interested.
