Ukraine didn’t break the Minsk agreements and no reputable source claims they did.

Russia invaded Ukraine because they fear neighbouring states that aren’t under Russia’s boot.

If you were a communist you’d recognise that Russia is a totalitarian Oligarchy and a terrible place for the proletariat.

Excuses are great, still breaks a treaty.

That sort of thing has a real cost in geopolitics.

Yes American promises are why Russia invaded despite being signatories to a treaty guaranteeing Ukrainian sovereignty.
