I don't know if you have seen the movie Hotel Rwanda, but I have never seen a more anti-UN movie. I'm sure that was NOT the director's intent. I'm sure he wanted the UN to look heroic, with Nick Nolte and all, but they end up looking like worthless idiots. At one point Nolte shoots his gun into the ground to "scare" the Hutu thugs, because they aren't allowed to shoot anyone. I kept thinking that if the US was there, the massacre of those million people would never have happened.
I thought it was not only very biased, but actually very pro-UN. The central thesis of the movie was that the REALLY bad guys were the US and Europe for not giving poor Nick Nolte and the UN more troops. The movie even managed to blame Belgium for the fact that the tribes were hacking each other to pieces -- Belgium who had not been around for 30 years when it happened. Never mind that these tribal divisions had been fighting for 500 years.
