US the only way for a peaceful world? You should read a bit on the USA history and its military conflicts and you may change your mind. Wikipedia is a good starting point.
The period of US hegemony from WW2 until today has by far been the most peaceful time in the history of civilization. Unlike previous super powers, the US did not take over any other countries or colonize by force. We have done many horrible things, like support dictators, invade Iraq based on lies (to depose a dictator), etc., but we have also supported people all over after natural disasters, helped with foreign aid to relieve famines, policed global trade to enable fair markets, and many other good deeds. It's definitely not the only way, and we could do much, much better, but show me another major country that you would prefer hold the reigns of global power?
Peaceful for who?? Certainly not for Latin America, Africa, Eastern Europe, South East Asia, Middle East. The US has absolutely imposed "peace" by force and by pushing its own agenda everywhere.
I beg your pardon? Eastern Europe is eternally grateful to the US that they won the cold war allowing them to break free from the Big Bear. Nations comprising 100+ million people from Estonia to Bulgaria are living their golden ages right now, because of US.
