I guess you forget when, after the Soviet Union fell, we disarmed the Ukraine, telling them that we, the West, would spring to their defense if they were under attack.
It is interesting to note just how you feel about tyrants invading and taking foreign countries. I wish we could boot you out to Russia, you'd be far more at home there, and it would help make the US more "the land of the free" than with your presence.
In reality everybody knows that Ukraine was disarmed for a non-proliferation reasons no matter what was promised them.
Africa is in flames right now because they have supplied everyone who had sticks and stones with rifles, and guys who could only afford rifles got their tanks, APCs and aircraft dirt cheap.
Ukraine have sold a carrier to the Chinese for some freaking $20 million, given them carrier aircraft to learn technology and operation, and where do you think rogue regimes learnt a rocket science?
Now imagine if Ukraine had the nukes. Even Mexican cartels might could have couple by now.
