I don’t like the expansion of NATO, but due to Russia’s recent imperialism, Sweden’s and Finland’s reactions are completely reasonable. A much healthier alternative would have been actually advancing towards an integrated European defense system involving EU members, with a door open to certain neighbours such as Norway, but it’s pretty hard to do that when the political groups that could actually promote that alternative are schizophrenically tolerating positions such as “I’m a pacifist, so I’m advocating for my own country’s disarmament despite my neighbours starting wars very recently” and “if Ukraine didn’t want to get invaded, they shouldn’t have sought guarantees against Russian aggression from third countries”.
