> The US probably hasn't been this economically dominant since after WWII. That may be true if you look at the US in isolation, they're much richer now compared to 1950, but they've never had a strong a contender as China is right now. The Soviets were matching them militarily back in the Cold War years but they were never close to surpass them economically, like China is now in the process of doing.
