So if its over then why has NATO and its allies been expanding right up to its border ?
NATO doesn't expand, nations freely get to be part of it on certain conditions if they so want. Usually they think they need protection from someone else.
Though NATO may look like it is expanding, you could say in capability it has actually shrunk making it more vulnerable. You could take that up to now, as a example of it didn't think Russia was a threat anymore. Something which has now changed.
So that begs the question, why are the Russians so afraid of freedom and other countries having free will.
