> It's about the nukes. Europe doesn't want a world where a lot of countries have nukes so the role of the US in Nato was to provide Europe with a nuclear umbrella.

If anything, it has been proven that unless you have nuclear weapons, your country is at risk of being attacked by nations that have them.

Ukraine learned this the hard way, so did many other countries in the Middle East and elsewhere.

In its defence, Sweden does have lutfisk, that's a pretty potent deterrent. Not quite as nasty as Norway's strategic surstromming stockpile, but still enough to deter invaders.
