There was also an ongoing sense that the President’s moral structure was, shall we say charitably, unconventional to the military mind. Cadets and midshipmen at the service academies operate on a very simple honor code: to not lie, to not cheat, to not steal. Every year, a handful of young officers run afoul and are summarily dismissed. For those who follow along the career path, any officer who violates the Uniform Code of Military Justice in any way–from sexually propositioning a subordinate to misrepresenting the finances of his unit–would be court-martialed and removed from the service. The President’s style of playing loose with the truth and facts–including by saying on Jan. 2 that he “essentially” fired Mattis, something he did not do–grate on the military mind. General Stanley McChrystal, who retired during the Obama Administration, said in a recent interview that Trump is a liar and an immoral figure. His blunt and direct comments provide a pretty good summary of what most generals think about the President’s character.

Perhaps the better question is, What attracted Trump to generals in the first place? It seems he was attracted to the macho, direct, domineering profile that many civilians associate with generals, like Jack Nicholson’s portrayal of a Marine in A Few Good Men. He may have thought associating with them would burnish his own credentials as an alpha male. (Remember, he also hired General Michael Flynn, who later pleaded guilty to making false statements to the FBI.) But it has likely dawned on Trump that generals are more cerebral than he ever would have guessed, have a pesky habit of quietly judging him in ways that got under his skin, are more intellectual planners than operational Rambos, and don’t quite care about the politics and media signals that the President holds dear.
