I'm pretty skeptical about the whole Nazi thing. There's definitely Nazis in Ukraine, they've been quite open about it. But how deep it runs? I don't think that much.

Even if it was totally Nazi at this point, Putin isn't the saviour lol. Putin's motivations were clear with his monstrous essay and obsession with ancient Russian history. His second motivation is, of course, strategic and self-interested again: Oil, direct access to the sea, and a buffer zone around Crimea.

I doubt he gives a flying fish about Nazis in Ukraine, tbh
