WWII was everyone destroying each other and the US came out on top because it still had an economy afterwards. That is a great example of the only winners being people who were an ocean away on a mostly peaceful continent. The US has spent the last 50 years fighting wars. China has not. China has grown by approximately 1 US economy (a bit less accounting for the fact that their figures are bogus). What was the point of the last 50 years of war? Where is the upside from all the US's killing? Because as far as I can see, most of the upside seems to have been in Asia.
