The US is often between a rock and a hard place between isolationism and being the world's policeman. I, for one, really don't care about the rest of the world one bit. I say that we should fight for our survival and nothing else. I think we should not give one dime to any nation unable or unwilling to ever pay us back. I believe that no nation could ever be our "friend" as government's don't have friends, they have interests. What is best for America is not of anyone else's concern, nor is what is best for the rest of the world America's concern.
