Ukraine is Khazaria. It’s where all this started, and it’s where it will begin to end.
As long as Biden is POTUS, the risks appear (to me) to play out this way.
The first to launch any long-range nuclear warhead will the United States.
It will be prompted by Russia sending a missile-message to a NATO country, depending on who Biden cajoles to send troops to UKR (I’m guessing Britain).
The RUS missile will not be nuclear but will act as proof-of-concept that the Bear can reach-out internationally.
Given the response timeframe and Biden’s desire to be a reactionary leader (”leading from behind”) the US will simply fire a nuke at St. Pete, assuming the RUS missile is nuclear.
Chaff
Biden is a threat to every American.
