I wish people would take batshit conspiracy theories out these discussions.

The US doesn't need external reasons for defense spending. Trump (nor anyone else in the GOP) is going to cut defense spending. So that's all just something you made up in your head, but isn't at all a real thing.

The Soviet control of Eastern Europe actually was a big thing in the Cold War. It's actually what the cold war was mostly about. So what are you talking about Soviets controlling Ukraine was no big deal?

And you should read up on the Helsinki Accords https://en.wikipedia.org/wiki/Helsinki_Accords

That agreement (and many more that followed on from that) countries in Europe agreed to respect each other's sovereignty. Mostly because they didn't want another World War. Putin has violated those agreements.

This isn't just ideological, though when a fascist invades a neighbouring country on the grounds that people of their ethnicity lives there, it raises some concerns doesn't it? But at any rate, Russia invaded a sovereign democracy. It's only right that all of the democracies of the world oppose this.
