Do they think magically the repressive government of China will assume the moral, military, social, religious, and technology leadership roles in the world?
I am one of the people that believe that U.S. leadership was earned by more than the size of it's economy. America worked to be a moral and human rights leader in the world. Many nations around the world owe their very existence to America. Without America, their invaders would still have control of their country.
I also believe that it might be a great blessing in disguise if America now takes a step back from world politics and political struggles, and concentrates on improving it's domestic situations and conditions. Let others, you know those arrogant European nations, deal with China and the global issues facing the nations of the world. Right now American will give foreign aid and comfort to itself. America will emerge stronger than ever from a domestic cleanup phase.
America should force the U.N. to be moved somewhere else, China?, and stop all foreign aid during our domestic cleanup process. Let other nations give foreign aid for a while. For decades America has been giving too much to too many.
America has a more important cause than being the default global police. America's domestic situations will be America's "raison d'etre" (reason to be) for the next 1 or 2 decades. America is going to restore it's own institutions to the level of competence, ethics, and efficiency they should be. A little isolationism and wound healing is always good for the soul!
