As an aside, communism is the evisceration of the proletariat by the bourgeoisie. It is alive and well. The only thing that’s dead is the myth that communism is a worker’s movement or that it was meant to liberate anyone from servitude. Their goal is a borderless world with a powerless underclass to be ruled by racially superlative academics and political technocrats.
The US more powerful than China and Russia? Hmm, I'm not entirely sure.
In total economic output, measured in real terms, China’s is already today 40% larger than America’s. This throws into the mix America’s massive service sector, which accounts for much less of China’s economy.
In total industrial output, which is widely considered of more relevance to war making, China is already the equivalent of the United States + Japan + Germany, all combined. Their manufacturing industry is over 80% larger than the US. Put another way, Chinese industrial power is 180% of America’s.
In both raw economic and specifically industrial might, the gap between China and America, gaping wide as it already is, is growing rapidly into a vast chasm.
By 2025, China’s economy, conservatively, will be 50% larger than the US, and their industrial capacity easily TWICE as large. By 2030, China’s economy will be the equivalent of that of the U.S. and European Union, COMBINED.
