Putin has effectively vowed (and for the better part of three years also attempted) to slaughter them anyway. To them the threat of nukes just translates to “if you don’t stop fighting back while I try to kill you, I will try to kill you even harder!” That certainly wouldn’t stop me, that’s for sure.
Yes, I’m aware of that. I just hope Vladimir is, too. At any rate he cannot be allowed to hold the whole world* hostage by playing chicken with unsubstantiated threats. The sooner he is stopped the better.
(* Except for China and his other buddies he’s scared of, of course. Which is somewhat ironic, considering how young Communist China used to be such a fan of the USSR, which in turn treated its poor and underdeveloped neighbour with so thinly veiled contempt. How the tables have turned…)
