I am sorry, you are blaming the United States for Russia invading Ukraine? Because Ukraine wanted to join a defensive alliance to protect themselves from a country that invaded them in 2014 and tried to keep their puppet in power before Maidan punted him?
Hilarious.
Do you think it is realistic that a (relatively) small country next to a superpower seeks protection from the rival superpower ?
What would happen if panama wanted to join a defence pact with Russia ?
What happened during the Cuban missile crisis ?
I wish all countries could be independent and free of meddling from superpowers. But at some moment you have to be realistic.
