I would say that the UN is in no position to tell either side what to do untill it can manage to secure the region militarily. It's like two people who refuse to keep punching each other, even if one of them wants to stop they know that doing so will only mean getting an even more severe beating.
I've been wanting to scream this for a while so I'm going to get it off my chest:
WHY THE HELL DO WE THINK THE U.N. IS STILL CAPABLE OF DOING THEIR JOB IF THEY CAN'T EVEN SEND 20,000 TROOPS TO SECURE A SMALLISH AMOUNT OF LAND!!!!
They make the current administration here look like a bunch of Cambridge scholors for pete's sake!
