Yes, yes, and yes. The Security Assurance to Ukraine (in return for them giving up 5000 nukes) was reaffirmed as recently as 2009 (ie., by Obama, he can’t even claim this was some mistake by a previous Pres.) Look it up on Wikipedia. It was actually one of the best things Clinton did (except perhaps for not actually been made a Treaty), because the alternatives were so bad.
I believe this (because it was / is so major, and is, er, was, a formal Security Assurance) is the final straw. No U.S. ally can depend on us any more, they will develop their own nukes, that will ratchet up the global arms race, and with so many players, a nuke war of some form is inevitable now. If lucky, maybe it will only involve 100 warheads or so. I don’t know what that much radiation floating around the globe will do, but if one looks thoroughly at the aftermath of Chernobyl and the large area affected, to this day, it is pretty scary. (And I’m still pro-nuclear electric power!) A dust-up between, say, a nuclear armed Taiwan and China will affect us big time, even if we are not directly involved. Shoot, in most bodies of water in the US, the fish have more mercury from China in them than they do from the US.
We have posters on here saying it’s not worth our while to honor our FORMAL commitments. Bah! I suppose we will get what we selfish bastards-with-no-honor deserve...
Under Clinton, the U.S. swore to protect the Ukraine. I really do believe Clinton would’ve handled this with force. He would’ve sent military assets to Crimea about 4 or 5 months ago and established a U.S. military presence there. Obama is ‘OUT TO LUNCH’ as usual, as he was in Iraq, Afghanistan, Egypt, Benghazi, etc.. If a major superpower would like to take control of the United States, now would be the best time to make their move. Obama is GUTLESS. He’s a scared woman in a suit.
