The majority of the Finns also support this move.

Finland having the courage to send arms to Ukraine already was pointing for the move to join NATO.

On Sweden things aren't as clear yet.

Putin can claim that getting a piece of Ukraine deserves the price of seeing Finland and Sweden joining NATO, but he will get the latter without having the former.

I'm still astonished as how a successful dictator could take this stupid decision.

Some say that his isolation, caused from his fear to get Sars 2 (the big tables are proportional to his fear), can explain his paranoia and this absolute blunder.
