I have been looking at American issues, mostly. Brexit, I followed that, but Ukraine, Russia? Sure, I know, there is bad stuff going on.. I don't have a good memory for things that are not In my life. And I don't know much about why this is happening Now.
I just stumbled across an article and I don't remember any of this. But then, I was working long hours and raising a kid. So,here's a link.
No, I'm not fact checking it. I'm not saying it's accurate. I'm tossing this out to see what everyone thinks and what should we do?

If you read that, it says we negotiated a deal that defanged Ukraine, and promised protection.

After the collapse of the Soviet Union, we went in to make sure the nukes weren't going to be stolen.  IIRC, a couple were unaccounted for.  Regardless, it was not to offer support indefinitely.
