Nothing has changed: Russia still fights the Nazis. There are countless videos of Ukrainian Nazis and even Ukrainian kids brainwashed into jumping and chanting nazi (anti-russian) chants.
tbf, the USSR fought the Nazis mainly because they didn't have much choice after Nazis turned on them a little while after they'd teamed up with those ideological enemies to invade Poland, so it's not like they hadn't put the effort into being on the wrong side of history :)
Oh, typical Ruzzian victim comlex, their brain can't understand why all their neighbors and "brother slavs" hate them, brainwashing for generations made them think in unatural logic where you need to negate anything a Ruzzian says and then you increase the probability 100 times to be the truth.
Ruzzian = a Russian Zed patriot , we use this notation to acknowledge that there still exists a small percentage of educated Russians that are not Ruscists.
