Putin came out of a different era in the history of Russia, He probably does think in his own mind that he alone was a great leader of Russia. Putin thought he could intimidate the world into believing that Russia was strong militarily. Even China and Iran bought into that one.
Russia has been at war with Ukraine for two years, and Ukraine is being supplied by America and NATO countries, but it is still just Ukraine that is fighting. Now we are watching Ukraine strike back into Russia, nothing like making war visible to the Russian population.
America learned the hard way in Afghanistan and Iraq that war is still not the solution in the 21st century. Just too much visibility for everyone to see. I doubt anyone really wants to see war close up and personal anymore. It is brutal, just like the world has been watching in Gaza this past year. Of course, Israel has not had to deal with actual war, a few missiles once in a while, but nothing as brutal as the leveling of an entire city, like Gaza.
Trying to imagine if Putin actually spent money on infrastructure around Russia or made life better for the average Russian. Russia could then use those advancements to make themselves a strong nation. Instead Putin is rich, the average Russian is poor, and Russia itself is floundering on the world stage.
