> I'm trying to understand the scale of Putin's decision
Drastic. Catastrophic. Suicidal. World-changing.The country (Russia) in its current form has just ceased to exist. The entire parasitic elite class just got cut off from everything they stole during all these years. The entire human potential of Russia just got nullified for at lest 20 years. The push towards green energy (and I hope nuclear fusion) just got accelerated. NATO and EU memberships just became essential for any European country. The prospects of nuclear disarmamant are nullified.
The war isn't exactly a blitzkrieg now, but it still has a good chance to succeed -- but that's not what matters. It's the consequences that matter. They will affect the course of human history.
I think the west (Europe and USA) will be perfectly fine. It's we Russians who are fucked for the rest of our lives.
