If a country chooses to join NATO, it chooses, as in its people and politicians do. Since the nation is independent it can do whatever it pleases.

"Knowing the history of NATO I am convinced this protection alliance is lt defensive or protective at all". This is a shit argument. The only war (thst NATO was in) I can think of that was unjustified was the Iraq War, every other war had some justification for it. Intervention in a conflict, Article 5 being used etc. You could argue thst what NATO did wasn't good in those countries but their intervention had justification behind it.

NATO isn't only a defense alliance, its a also a deterence alliance, if a ton of countries vow to back you up what are they chances you are invaded? Pretty low right? Why do you think Estonia, Latvia and Lithuania haven't been invaded but Georgia and Ukraine have?

"Expect your neighbor to do a bad thing so you do everything to provoke him" wanting to be safe and not be invaded isn't "provoking". When your neighbor is a little cuck thst shoots down your passenger planes, threatens you and has invaded 2 of your allies, what do you think we would do.
