China

China catching up in science. I'm probably the only China-bear left on the planet, but I do think they have one distinct advantage today and that's a national sense of purpose. I believe a significant portion of the Chinese truly believe in their nation and feel destined to become the most powerful country in the world. Whereas in America today, we are openly hostile to one another, and a small, but significant portion don't even like America, nor believe in it. Or at the very least, none of their actions suggest they do. We've always become petty whereas they have delusions of grandeur. And I think delusions of grandeur, although dangerous is preferable to pettiness.
