education has nothing to do with this, an average university professor in Russia(or for a matter of fact in the west too) is a radical supporter of the mainstream media

The overall GDP tells you what capabilities exist in total. Life of Russians is significantly more impacted in post because they are redirecting a much larger part of their economy. Let's also not forget that the cold war was with the Soviet Union and not just Russia.

GDP is directly and strongly correlated to military industrial capability for sustaining a meaningful war effort. Modern history has shown this time and time again in many wars where enemies seriously applied themselves to pushing onward (I say this to exclude things like the Vietnam War, in which the U.S could have crushed the North but didn't have the political or social will do push it that far). Aside from its nuclear arsenal, Russia is economically and in terms of sustained war production no match for the NATO Alliance, even without the U.S. With U.S support, there's no chance. Putin himself even recently stated this, calling the idea of attacking NATO insane and specifically referencing his country's economic strength vs. that of NATO and the U.S.

Russia is just barely sustaining its war with Ukraine and the production capacity behind restocking destroyed and lost supplies. Never mind a war with NATO, unless they're willing to use nukes and risk utterly destroying themselves, and I don't quite think Putin is that insane. Even if he is, I don't think those surrounding him are, and their sycophancy would rapidly evaporate if faced with a real, immediate threat of their boss unleashing something that makes their decades of hard-stolen self-enrichment become irrelevant.
