And yet here we have Russia, the successor nation showing that NATO needs to be kept around so they don’t invade another neighbor. Remember, Crimea wasn’t the first time this century they’ve done that.
To your example, my neighbor would be within their rights to do that if I have a history of kicking down doors. But I guess violence only matters from one direction, nevermind that so many former client states actively sought protection from this shit happening, especially when Russia can’t be taken at their word to leave neighbors alone.
