You do know that this "defence alliance" already attacked 2 countries, which were not attacking any NATO member, right?
And even if the alliance really were just defensive, you realize that this means that all it takes to use it against someone is a successful false flag attack?
All i know is that they bombed Serbia, which did not wage war on any NATO country, for 78 consecutive days and more recently, destroyed Syria and Libya, which again did not invade any of the NATO countries.
Also it seems that NATO rebuffed Russia's attempt to join it. With Russia in NATO would have been the strongest defense alliance. I wonder why they wanted to keep Russians as perpetual enemies!
