I’m worried at some aspects of your comment that seem xenophobic in nature. Most Russians disagree with the decision to attack Ukraine and even a dictator like Putin can’t pull the string forever without breaking it. We already saw the consequences of him having to rely on mercenaries a couple weeks ago. He had to rely on them because there are not enough people willing to fight. So russians in general aren’t some zombies or pawns, we shouldn’t look at them that way.

On the other hand, I don’t see a real risk of Russia invading Sweden, and don’t even consider NATO’s response to a Russian’s hypothetical threat of invasion to another country to be the same, so in the end, while they didn’t get to join, I think they can move on without any damage and try joining later when conditions change. They’ll still be de facto protected.
