> I don't see any other explanation except that allowing NATO rockets in Ukraine is suicidal for Russia, therefore there is no choice: it is a fight for survival. > Think what US would do if Russia were to put its rockets in Mexico and/or Canada. Or just remember Cuba/Turkey situation in 60s. If it is just a defense pact and not first strike nukes, I wouldn't care. AFAIK, the US hasn't expanded nuclear weapons eastword since the cuban missile crises so I'm not sure what your point is. Estonia is part of NATO but we don't host nukes there because we don't want to trigger the Cuban missile crises again.
