Are you trying to "defend" Stalin and Lenin and Mao ???
I'm saying we attacked their nascent nations and have never stopped threatening them.
Furthermore, we're doing it from enviably safe geographic positions - while they're naturally vulnerable and our conduct is making them still more paranoid.
All the aggression coming from them is directly brought about by our threats to them, or for eminently understandabler geographic reasons.
eg the South China Sea is their Caribbean, but much more important to them than the Caribbean is to you.
While Ukraine and Crimea are urgently necessary to the Russians to have any means of self-defense, and still doesn't allow them much.
