You don't. The only way is to beat them into submission. Unfortunately, many of today's civilized world powers are either wusses.... or they just don't give a shit about anything that happens outside their borders. See no evil, hear no evil. And when the U.S. intervenes... guess who gets shit thrown in their faces.

The more I think about it, the more I think the U.S. should demand that international peacekeeping organizations grow some balls. If we were talking people instead of nations, I'm sure that's what would be happening.
