I suggest this thread. Russia has already lost geopolitically and strategically. The Pentagon now labels Russia an “acute problem” and no longer a long term threat. Nuff said.
China can’t even project power out of the first island chain. They have 4x the US population and are still behind economically and still aren’t as productive as the average American.
Per Peking Uni, China is behind the US in most fields, equal in a few, and ahead in very few.
China is a strong competitor but they still can’t match US comprehensive power.
