This is not a complete nonsense simply from the fact that if a joining country has conflicts with a bordering country, then such a member would trigger the "attack on one shall be considered an attack on all".
> Putin has sent tens of thousands of Russians into a meat grinder, ego-driven war that has zero outcome that isn't negative for Russia for decades to come.
I agree that this war is stupid, but it could've been avoid entirely had the US conducted a constructive dialog with Russia.
Ukraine is grinding Ukrainian males the same way Russia is grinding theirs. People with cash has already bribed to leave the country. Those who haven't bribed yet get caught on the streets and sent to the war the very next week. Military folks don't care whether you are a software engineer who has never held a weapon in your hands or a 58 old guy who's about to retire.
Whatever is happening today is the result of something. That something has been brewing for years. The root of that something are the ambitions of NATO. Some countries simply do not want NATO to be around. And I don't get why it's so hard to understand that.
Edit: I'm a software engineer who has never fired a firearm. Had I been in Ukraine right now, they'd sent me to the war as well, because they mailed my parents all the papers. Luckily I left the country many, many years ago.
