They're obviously not passive puppets. They had a choice - they could do what the US wanted, or what Russia wanted. That is more agency than most countries get when facing an existential crisis.
However, given that they chose to align with the US and we now have people talking in uncontroversial statements about it being a "pre-war era" the unfortunate reality here is that the option the US gave them was/is a diplomatic disaster that is very much in line with the US's NATO expansion strategy that they've been executing for the last 30-something years. It is a bad strategy that is leading to war.
> Nobody pressured them to do anything. Russia's actions are all offense, full stop.
Avoiding war requires both sides to reach some sort of mutual understanding. The Russian's aren't going to buy that bullshit. A lot of their troops just died because of NATO arms, held by troops that were at least in part NATO-trained, using NATO intelligence and NATO-approved strategies in a war that is part of a broad strategic push, by NATO, into Eastern Europe. They've figured out the role that NATO is playing here; the plan is obviously to contain and militarily cripple Russia.
That style of rhetorical bullying is very prevalent amongst western leadership, but if we want to find a peaceful solution they should be more honest. They provoked this.
