dnc101 - I agree. I think people all over the world would be shocked to see what happens if we withdrew any activity in the rest of the world.
Unfortunately every country needs the rest of the world to survive, we wouldn't be a world power without the rest of the world regardless of how self reliant we like to thnk we are. We might be able to do a better job of surviving then some places but it would get bad hear too, and I think Americans would be shocked just as much.
