You think Biden knows that? He is a walking, talking, bumbling embarrassment to the office of the presidency. He pissed off the King, big-time, as well, with his stupidity….trying to have a conversation with that guard lol
He messed up with the Queen 'cause he kissed her hand. . .you don't EVER touch the Queen. Then there was that screw up with the China and the bowing. . .first of all wrong country, second it's a sign of apologizing and/or acknowledging a superior. . .oh, wait. . .maybe that one wasn't a screw up. . .
And stupid libtards don't understand how other cultures or basic diplomacy works. How even the slightest of errors when visiting another country in an official capacity can make the country look uncouth and uncivilized. . .of course libtards don't care about the USA's standing in the world unless it's bad. . .
