That is NOT going to happen! WE will not let it.There is one BIG difference here.
As we entered the 20th Century, European powers dominated most of the world. As we moved through WW I and WW II, the United state became the preeminent power bot financially and militarily briefly challenged by a bankrupt Soviet Union. Now in the early years of the 21st Century we are facing huge deficits, a dwindling revenue base and a foreign policy that allows small despots to kick sand in our face. Meanwhile, China essentially holds the keys to our financial system while they pour money into their economy and modernizing their huge military. They are not limited by political special interests and whacko environmentalists. Napolean once said “China is the sleeping giant and when she awakes, the world will tremble”. I believe she has awaken and we may well see in the 21st Century, China emerging as the pre-eminent power in the world.
