“Being a Democracy” is not a significant military criteria.
It’s you who are comming up with your own “selection criteria” which you then claim NATO is supposed to follow (even though the criteria you made up at times go against NATO’s very clearly and firmly stated aims), and then arguing that they don’t follow your criteria hence are whatever you feel like to label those who don’t strictly follow criteria you decided they’re suppose to follow.
That fantastic and circular line of thinking is all you, and quite unrelated to the real world.
