I have said it numerous times that we should have bought Russia into the fold as soon as the Soviet Union fell and got them "westernised" and integrated into the west so that they had enough skin in our game yhat they'd not be creating situations like the one in Ukraine.
Alas, there's no way to go back and test that hypothesis.
I doubt that would ever happened, Russia is too big and mentally (both internally and from Europe point of view) was always on other side of the fence and always looked with suspicion (and from Russian point of view, it was Europeans who always invaded them), even when they were part of various European alliances historically, them bowing to America like European states, no way.
Also i don't think America would vote for it, ever since 1945 Russia was big, bad enemy and used as excuse for various wars and interventions and funding of American military, them letting them into organization that was made to fight them, i highly doubt it.
