Despite the largely military audience immediately standing to show the proper respect for the lowering of the flag, Commander in Briefs Trump did not stand and show respect for the flag or for the military tradition.
He surrounds himself with actual military men, he boasts of 'doing the military so well your head will spin', but through his own actions and inactions, he disrespects the American flag and cherished military tradition while on base acting as Commander of the Armed Forces.
Wait for the outrage.
(…there won't be any, …there isn't a black target to point to here,
...just Trump, and he can murder America in the street and his followers won't care.)
