Well, there are people even in the US who think an isolationist policy and letting other states deal with their own matters without interference is the best way to go. The world would look different, for example less people in South America would be angry at the US for installing puppets in their country, there would be no Palestinia-Israel conflict ( ) and less people in Arabia would turn to terrorism to oppose US bases in Arabia, South Korea might be North Korea now, Vietnam might be North Vietnam now but then how is that any of our business? If the soldiers of Korea want to worship their "great" leader while their families starve, that's their decision. As Afghanistan shows, some people just don't value their freedom a lot when you force it onto them.
