I don't relish the idea of China becoming a superpower and exercising hegemony the way the US has done in the past, it would be WAY worse. But it's a very strong possibility we had all better prepare for.[/QUOTE]
Have you ever read "How Buidlings Learn: What happens after they're built" by Stewart Brand? Mostly, it's about how structures adapt through different functionalities over time. I like the McDonald's off the Jericho Turnpike on Long Island. Buildings adapt to changing times.
Comparing the United States and China in conventional great power terms is like comparing apples and oranges. China borders Pakistan. China borders North Korea. China has been involved in shooting wars with nearly all of it's neighbors over the course of the past 60 years. It has unresolved border disputes with at least three nuclear powers. Think Germany 1866-1945. The stronger it gets, the more it's neighbors are going freak out.
China has some concerning demographics, something like 20 percent more men than women. That's a big deal when your country represents a huge chunk of the global population. The odd thing that worries me about that is the prospect of all those hard-up young guys trying to get laid. It's got to amount to 100 million guys without a partner. It's not like you can let 'em all lose in Havana for the weekend.
In contrast, at it's core, the United States is insular. The last time we exchanged gunfire in any significant way with either the Canadians or Mexicans was before the American Civil War. I think we are the second largest Spanish-speaking country in the world now, or we soon will be, and that matches up nicely with our position as the second-largest English speaking country (not much point to learning Hindi or Urdu in my opinion). For the most part, we can pick and choose our fights. If CHGB is right, and it all boils down to chess, then the USA is the piece with the most dynamic energy and freedom of movement and it's likely to remain so, barring something that ends the game.
