Strick,

The notion that the USA wants to be isolationist is a little off, excuse me for saying. It needs oil, and lots of it. It needs much that is produced elsewhere. No one--since the Canadians when fighting for the British in 1812-14--has invaded the USA. (We did apologize for burning the White House down.) Saying the USA would like to be left alone by the rest of the world just ain't a fact. Saying it don't make it so.
