Absolute nonsense...the United States did nothing of the kind.
Then correct me.
Don’t just say I’m wrong.
My colloquial summary may be, strictly speaking, incorrect - sure. But that’s kinda the point of what happened: USSR collapsed, Ukraine was liberated, everyone realized a $#!^load of nukes were still still sitting there, Kiev gave them to Russia on promise of protection from Russia. A variant on the “hand over the gun and nobody gets hurt” trope.
