A good friend sent me this article knowing my view of the United States' eventual title loss as the top global power. I want to pass this along to others who may be interested. I have received similar lectures in a few lectures on Political Science and it's going to be quite the roller coaster ride over the next few decades. So tighten your seat belt and let the globalization game begin.
