I think that it is a mistake to categorise Russia in the same grouping as the US and China, who are streets ahead in terms of economic and military power. They have the two largest economies and armies in the word, Russia’s economy is smaller than Italy. Russia has also been hugely depleted and exhausted by the Ukraine war. It also faces particular demographic challenges that the US doesn’t, although the birth rate in China is also a ticking time bomb, but I believe they have the wherewithal to substantively address that.
So I simply doesn’t see how Russia has the capacity to impose itself on its sphere of influence to anything even resembling the same extent as US and China, especially as a united Europe has the conventional military capacity to repel, or at least absorb Russian aggression, even without the assistance of the US.
I can readily see a world dominated by two global superpowers, but to assume Russia will be a third simply doesn’t bear any objective scrutiny and is simply based on its sheer size rather than a host of other equally relevant factors.
I think it faces huge issues, which the other two don’t, notwithstanding the potential long term vulnerability of the dollar.
