Well, the UN is comprised of several powerful member countries which can enforce its actions through action of their own. They just won't, as people have been calling for international intervention in Sudan for years and no one has bothered, especially not the U.S. which for better or worse (mostly worse under Bush) is often the leader in those types of things. Bush of course chose to ignore it completely as there was nothing in it for him, plus we are so entangled right now it'd be stretching us even thinner.
Surprise, surprise,
Iran, Hamas, Hezbollah, Palestine's Islamic Jihad, and Syria are all backing al-Bashir. His indictment is, of course, a Western conspiracy. I had high hopes for better relations with the Middle East but it just seems that all the power groups you actually have to
worry about are so far out of the mainstream thought of the majority of the world that it's just not going to happen in the majority of my life time.
