The part you conveniently didn't mention is that Ukraine's nuclear arsenal was aimed at Western cities. They were part of the USSR, they were the commies
Just saying
Operative word "were". They were sold on this utopia and surprise surprise it didn't work out. Afterwards they didn't want anything to do with communism. You are talking about pre 1991 Ukraine which was really taking orders on behalf of Russians.
After their independence they made it abundantly clear they wanted nothing to do with Russia and join nato and be allies with the west.
Ukraine actually was paid for turning over their weapons, as part of a side deal they negotiated secretly because Kazakhstan and Belarus were not paid.
Your comment on Cuba is wrong also. Russia was the threat at the time, which is why they were doing it, but the result would have been the same if someone else tried the same thing. If France moved weapons into Cuba it would be interpreted as an act of war against the United States too. It doesn't matter who does it, if anyone tries to move into the western hemisphere America has a policy of considering that a direct threat. This same policy secured Canada's ability to help Britain during WW1 with no fear of domestic attacks even before America entered the war. An attack on Canada would have been considered an attack on America even before NATO, even a legitimate attack during a world war wherein Canada was a belligerent aiding in attacks on other countries. It doesn't matter, they're not allowed to bring any of their European bullshit over here.
Russia wishes they could enforce a similar policy, their only chance is on a much smaller scale(Ukraine). NATO was moving weapons into Ukraine whose only purpose was to kill Russians, they interpreted that as a threat because it was a threat.
Well you might be right they didn't entirely get nothing, but they were paid cents on a dollar for the large amount of uranium. Still incredibly poor deal. Like going on an episode of pawn stars and Rick offered you $10 and 1/2 a slice of pizza for your Rolex.
United States has the most military bases on the planet by a large margin, it sets up on other people's backyards then cries when other contries do the same. Its pure cope
