Coming from a country bordering Russia and having had to deal with their bullshit for my entire life, the most frustrating thing about Russian bullshit is that if they could just be normal, they could be an actually wealthy and significant European country in a few decades. But no, they have always had this HUGE inferiority complex, which means that they need to continuously prove that they’re great, powerful and important. And the only way they know how to prove their greatness and importance is to flex their “power” on their neighbors, including by militarily expanding their borders, while most of their “peer” countries (most importantly pretty much all of Europe) have moved on from this sort of view of being “powerful” after WW2 by the latest.
