According to CNN, it looks like with Aristide's departure the U.N. is going to send peacekeepers into Haiti. Fortunately, it may not be necessary; the rebel leader has said that with Aristide gone, they "don't intend to fight anymore... the only problem we had was with Aristide". I'm not going to bet money on complete stability with Aristide's ouster, especially considering that "pro-Aristide gangs" have been causing trouble in the capital, but without American support, he's ready to have that proverbial fork stuck in him.
Regardless of that, I fervently hope that Phillipe was being honest. I've been worried about Haiti for a while, and any outcome that doesn't end up with Haiti in flames is much more positive than what I've been expecting.
