Yes, thats why we intervened when Russia tried to set up nuke missiles in Cuba.
So then why have Russia and China not built military bases on our side of the Pacific and Atlantic?
Because they are steeped in history, and they know the Monroe Doctrine is still in effect, and even if the Big Guy doesn’t want to enforce it now, the next President will.
Doh.
Of course, neither Russia nor China cares one bit about the Monroe Doctrine anymore. If you’d review it there was another side to it, to keep out of European affairs.
If the USAF thinks it is entitled to have missiles on the Russian border then Russia is entitled to have theirs on Cuba.
