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.
nato is just a paper tiger and is becoming more and more one (crime crisis, Currency Crisis, Media Trust Crisis)
its completely pointless to join it, and also provokes conflict, you will end up having only a political caste being part of nato, no one else.
