The rest follows naturally: Antony Blinken is not a serious diplomat. Samantha Power is not a serious diplomat. As a diplomat (and various other things), Hillary “He’s Hitler” Clinton is a walking calamity. Biden, who’s spent his career selling snake oil off the back of a buckwagon, is not a statesman of any kind, serious or otherwise.
