>> NATO:
None of those involved NATO forces invading a country. There was no invasion, no conflict.
As always, every country that has joined NATO has asked to join NATO.
Finland joining NATO was not an act of aggression against Finland in any sense of the word.
That Russia perceived it as an act of aggression against Russia is irrelevant, and says more about Russian paranoia than it does about NATO. And is exactly why Finland, Hungary, et al., felt it necessary to seek NATO membership.
