Putin’s alcoholic butt buddy Dimon has been threatening the West with WWIII for years in a series of regularly scheduled hissy fits. He even threatened to fire a hypersonic missile at the ICC for their indictment and arrest warrant of Vlad the Butcher/Pedophile. Most people have ignored him, except for the Putler fanboiz here (we ALL know who they are!) But threatening Trump is a new one, which puts him on the same side as the other Zelenskyy-hating maniacs on FR.
It could be a threat if one believes Lee Oswald was sent by Soviet backers (or Cuban) to kill JFK. It could be analysis if one believes that JFK was killed by forces within the CIA-govt realm as it existed in 1963.
Key would be what medvedev believes happened in 1963, and I don’t know which of those two he believes. (I would say more likely deep state than Soviets but I didn’t make the comment). If anyone knows any details of Soviet-Cuban involvement it would be Putin.
