No. You prove your nonsense.
Part of US culture, since the founding fathers, is that a POTUS never ever bows to a foreign leader. NEVER. This was in response to the American value that all men are created equal especially in the face of Royalty.
I think we all need to just address him as President Trump from now on.
protocol is not MY nonsense..and yes, they do. now this is tiresome. they follow protocol. period. it is not demeaning. it means something entirely different than you seem to think. and I do not have to prove that our leaders follow protocol. it is a fact. you do the research if you have questions. I have none. I know they do.
