Why do we need the UN?

The following is a real opinion post. This is not made up.
Paul Rusesabagina, the real life hero and basis for the movie Hotel Rwanda, had this to say about the UN Peacekeepers in Rwanda. "the (U.N.) soldiers ran away and left us on our own." He would know, he was there.

Even though the movie Hotel Rwanda is up for an Academy Award, it's still worth watching. Set in the sub-Saharan African nation a decade ago, it shows how a man and his wife refused to sit by and let Evil stand unchallenged. Paul Rusebagina was managing a hotel when the call came for all Hutus(one ethnic group) to throw off the shackles of law and murder any and all Tutsis(minutely different ethnic group). Because of government instability and no checks and balances on said government, the military and police were populated by extremist Hutus. The minority Tutsis had no recourse but to run for their lives. Paul and his wife(Hutus themselves) used their hotel as a place to shelter all the harried fearful Tutsis they could find. Knowing full well that they would be killed if the wrong person found out what they did, they continued to selflessly put their own lives on the line to protect these innocent civilians. In the end, over 500,000 Tutsis and politically moderate Hutus were killed. But because Paul and Tatiana Rusebagina refused to back down, 1,268 people were able to continue living. This story has more in common with The Hiding Place than Schindlers List. But watch it, learn from it, and stay tuned for my next piece. I will be taking a more in depth look at the UN and their "successes."
