"The Western liberal and democratic order was triumphant to such a degree that when Westerners invoked “the international community,” they instinctively assumed it reflected their views on government and human rights."

Remember those "innocent" days of 1990? When the Cold War ended many hoped there would be a "peace 
dividend". But the US shattered that hope with the Gulf War. The new Islamic enemies were created as smoothly as Churchill created the Cold War as WW II was ending.
   It was obvious that American "exceptionalism" was going to replace global communism with global fascism.
It's probably better for the possibility of world peace that several major powers have their spheres of influence. Nobody wants the US to be the world's policeman..
