I think we should condemn the morons that make such suggestions, rather than the poor chaps that staff the military arm of the UN. Those guys generally deserve our respect. The come from all over the world and have to work in some pretty dire circumstances, with crappy rules of engagement. Nevertheless, the tread on. I can think of some Rangers and guys in Delta that probably don't have an ill word to say about them.
Though you may be at least partially correct in this opinion, I will say that the UN is neither needed nor would they be welcome in this country.
