I'm not saying I have better insight about that war, but from my understanding, Ukraine shouldn't join NATO
Well it's a good thing that from the understanding of the people who make the choices you're in the wrong.
I think it should be readily obvious why the USA should defend a country against an act of aggression. For one thing, violating international boundaries and seizing land through war ought to be punished. The precedent should be set that doing so brings about international rebuke and strong consequences. For another, the USA made a security guarantee to Ukraine when they gave up their nuclear weapons. We should make good on it.
Ukraine joining NATO would have prevented this war. Russia isn't going to war with a country in NATO - just look at the Baltic states. They joined NATO to protect against a possible Russian aggression just like what's happening now in Ukraine. That worked. It would have worked for Ukraine and it's part of why I believe Putin pulled the trigger on this before Ukraine was in NATO.
Okay I didn't watch the video until looking at your link and saw the whole "he started saying migrant wrong" bullshit and was like, "okay maybe that is what happened.". No, this dude straight throws a hard r n word out casually, unmistakable as anything else.
