You can't spell 'completely fucking useless' without UN

Can anybody tell me exactly what it is that the UN does? I mean, besides taking up perfectly good real estate in New York. What exactly does a government have to do to its own people before we take action? The crisis in Sudan is just the latest in a very long list of failures on the part of the international community.

And, while I'm on the topic, does anyone else find it somewhat vulgar that there are basically only two nations with troops on the ground monitoring the situation, and one of them is Rwanda (Nigeria being the other). "Hey Rwanda, remember how we all stood by and watched your genocide ten years ago? Yeah, well, that really worked for us, so we're thinking about doing that again, but this time in Sudan. So, if you could maybe send some troops and make it look like the world cares a little bit, that'd be great. You won't have to doing any stopping of atrocities or anything, just stand there with a concerned look on your face. The optics are much better that way. Thanks!"
