On Darfur, I agree with G. Clooney if he means that good men and good nations should sweep away thugs, tyrants, genocide. It ain't UN peacekeepers going to do it. In these "neighborhoods", there should be mature, democratic countries whose people refuse to tolerate unspeakably evil murderers in their midst.
This is ISLAM in action, doing what it does best - mindless violence.
As for Cluney, he would be FIRST in line to criticize US if we started butchering the butchers.
