I remember watching this as it unfolded. I remember cringing - not for Øbozo but for America whose honor and reputation were being sullied by his ignorant and arrogant antics. He is supposed to have a Chief of Protocol who advises him how to not look like a fool but they obviously never hired one.
I know Hillery doesn't. Before any government official visit to any country or event a "book" is compiled. In it are a list of facts about the place or event and things to say or not to say.
There is no excuse for not reading this information but it is clear they do not.
Lack of a competent Chief of Protocol became obvious once the ridiculous gifts he gave became public.
