I'll be honest, I disagree with your takes, but I understand your perspective through the lens of you being Finnish.
But seriously, I get it. Living directly next to Russia without NATO status and without friendly relations to Russia is a ballsy move. I hope Finland gets to join NATO. I know you said that you see the war being like the winter war, but I think it's going to end up like the continuation war. A long slog that ultimately concludes in Ukraine ceding the strategic and oil+gas resource rich eastern areas to Russia.
