Thanks for your info. Nice to see that my general understanding of the U.N. and it's peace-keeping actions is pretty close to their official stance.
Should the U.S. go to Sudan? - troops? No.
The U.N. needs to figure out that any "recognized" government that is bent of killing or displacing a large number of its population, basically abdicated it's right to rule. Of course, the U.N. will never agree to that, because many of the most powerful nation in the U.N. do that as well, and they wouldn't want to leave that door open.
that is why the U.N. will never have any real teeth - those nations that control what goes on, are little better than the "evil" countries such as Iraq, Sudan, North Korea, etc.
