The UN observed mass murder in Yugoslavia and it observed Hezbollah stockpiling a 1000 rockets while enjoying a coffee. When there is really something to observe they pull out. The UN is a totally corrupt organisation of people who give their friends well-paid jobs. Probably, there are people in the UN who really want to make the world a better place, but they never make it to any top. If the UN did work, it would be patrolling Gaza to take out launching platforms, east-Jerusalem, and particularly they would be forcefully disarming certain parts of Africa such as DRC. I agree that with the 0 they achieve now, they are only a costly burden. Of course a country like Croatia then, or Israel now will want to take matters into their own hands seeing the white jeeps fleeing at the first sound of an explosion.
