Not gonna happen... The liberal politicians love the UN, and our so called conservative politicians don't have the guts to do it. Sadly, the word "isolationist" is all too often used to unfairly to describe conservatives like myself who have a problem with US foreign policy and US membership in the UN....
"isolationist" doesn't even fit -- what the hell has the UN done that benefits the US lately? North Korea and Iran are plunging ahead while El "debarge" Baradei sits on his hands, they aren't doing crap in Iraq, the Congo and Darfur are still in tatters and the former Yugoslavia is starting to simmer again. If this is isolationist then sign me up.
