As the Finnish minister said, they were not joining Nato years ago because it was their decision not to, once putin TOLD them they could not join NATO, he took away their self determination to not join NATO.That certainly wasn't the feeling at the time.
Keep in mind everyone thought Ukraine would be flattened within weeks, yet here we are in month 3. Inevitability is only as good as the partial picture we have. This is a royal embarrassment to Russia and all that military modernization they did which looks to have just been a way for oligarchs to siphon off money for yachts and vacation houses.
And how is Ukraine fighting for nothing? They're fighting for one of the best reasons there is to fight! A defensive war to protect their sovereignty and right to self-determination.
This was an attack on their soveriegn right as a country to make their own decisions, now they are joining NATO and as the minister said " You can blame Putin for Finland joining NATO."
