Emotional what? looks like your the one getting emotional here, there's nothing you say that will change the facts. i have told you exactly what i think of NATO. what rule are you talking about? the same rule US broke time and time again? ok, this time Russia broke the rules, why you crying about it? it's life move on. you didn't cry with the same energy when US broke the rules, you criticised them privately. only God knows if you actually criticised them or maybe you gave them a pat on the shoulder.
Russia invaded Ukraine because Ukraine wanted to join NATO, we have had this debate before but you won't let it go so i will throw more light into the subject from another angle. Russia didn't just wake up one morning and invade Ukraine, there was warning upon warning that Ukraine and Georgia can never be allowed to join NATO, one of those warnings came in form of two draft treaties, one to NATO and one to the US. these treaties proposed a ban on Ukraine joining NATO. they clearly said they will act if no one takes them seriously, NATO and the US rejected these treaties, they didn't even negotiate it. Russia invaded to protect it's national security.
why the pain and emotions? is it because the US don't control the monopoly of invading countries anymore?
