I disagree. I have no idea why anyone in their right mind would underestimate USA even after they have proved again and again why they are the most dominant superpower in the world in the long-term.
Russia and pathetic Putin are being criticised for the Ukraine war and their economy is suffering because of all the sanctions, COVID etc. This doesn't imply dominance in any manner whatsoever. Think!
From what I have seen, the Russian economy is doing just fine. Their trade surplus is at all time high and they are benefitting immensely from the sky high fuel prices. The West tried to boycott Russian commodities and the latter just rerouted the exports to Asian countries such as India and China. Now nations such as Pakistan and Myanmar are lining up to purchase Russian hydrocarbons.
