That's why we need police to maintain domestic order and need armies to maintain international order. As for the bad things the US did in the last 30 years, my question is that if the US did nothing in the last 30 years, would the world necessarily be a better place? Is there anyone else who could have stopped the Soviets, North Korea, Saddam, Iran, Al Queda? Can we enjoy the same freedom and prosperity we have today, or are still living under the shadow of communist dictatorship? You of course disagee with these, but I can assure you that if the US withdraw from the world affair and to care for only itself now, it could be one of the worst things that ever happen in our generation
