I wouldn't be surprised considering the developments. When this thread was made there was just a threat of Russian aggression, now Russia has actually invaded Ukraine. It's understandable that their other neighbors are getting uneasy.
I think it's final, I read that they retracted their decision to join NATO, due to fears of similar countermeasures from their Russian neighbors. To be honest, it's probably for the best, NATO aren't saints either, while their entry could potentially spark a large scale war. which would result in a third World War.
Finland folded? I think these countries that are not currently part of NATO should just form their own grouping that would serve as a buffer between Russia and the current NATO. That way they can get concessions from both and both would keep them intact like how Siam/Thailand survived the carving of Southeast Asia.
I believe it's just Finland, Sweden, Ukraine and Belarus that's bordering Russia that are still not NATO members. Obviously it's pretty late for Ukraine and Belarus isn't gonna try joining any time soon. If Ukraine survive this intact it should seriously consider talking to the other remaining buffer states to team up.
Uh, Belarus is a Russian outpost/ally, not to mention that it was hostile against Ukraine. On the one hand, the countries that do not belong to NATO and are neighboring with Russia (Moldova, Finland, Georgia) could be susceptible to a future attack. On the other hand, Putin have threatened them if they decided to join NATO, and as we've already seen, he's not making blank threats.
