I have always said he should have cleaned house. It was his first mistake; now this crap is going on 3 yrs later.
Military people are always cited as going out to today’s war prepared to fight the LAST war. McMaster is no different.
He earned his reputation with a good analysis of how the Johnson Administration went down the toilet in Vietnam by ignoring the Joint Chiefs and the professionals and getting in a political echo chamber.
He then goes to work for Trump and throws out the political allies and uses staff that is all deep state. Same problem with reverse outline.
