The superiority complex most Americans display is quite laughably transparent. The chefs kiss is most of these people can see the US Empire collapsing around them.
Who are the "these people" you're referring to here? NATO's expansion is a wonderful Joe Biden/EU punch in the face to Putin--and Trump.
Putin has a massive inferiority complex--and it's well-deserved. The country has a lot of oil and gas and is a very wealthy gas station, and they have the capacity to make a lot of military equipment and sacrifice a lot of their poor ethnic minorities in a war, but all things considered Russia is, at best, a second-rate nation--maybe even third.
If Ukraine can drive Russia out of the Donbas, at the least, if not Crimea as well, and the war end, and Putin somehow stays in power and doesn't get shot or hanged for war crimes, and Ukraine joins the EU, Ukraine will become a more prosperous and dynamic country than Russia. That is certainly a big part of what Putin fears. A dynamic, democratic Ukraine will make Russia look poor and oppressed in comparison, and the Russian people will notice---not just the oligarchs and the mobsters who already know that Europe (the West) is more successful than Russia (that's why they all have homes in Europe, vacation there, send their kids to school there), but average, downtrodden Russians will come to see it, too---just as nearly all the people in Eastern Europe (Poland, Czech Republic, the Baltics) have come to see it since the end of the Cold War and breakup of the USSR--people who lived under the harsh Soviet boot. For them, never again. And if the Russian people see it--and let's remember that they don't really see it now because the state controls the media, massive daily Trumpian-like propaganda-- and most Russians don't travel and aren't educated--well, you could see unrest in Russia, at some point.
