That was never clearer than when Trump told his new chief of staff, John Kelly—like Mattis, a retired Marine Corps general—about his vision for Independence Day. “Look, I don’t want any wounded guys in the parade,” Trump said. “This doesn’t look good for me.” He explained with distaste that at the Bastille Day parade there had been several formations of injured veterans, including wheelchair-bound soldiers who had lost limbs in battle.

Kelly could not believe what he was hearing. “Those are the heroes,” he told Trump. “In our society, there’s only one group of people who are more heroic than they are—and they are buried over in Arlington.” Kelly did not mention that his own son Robert, a lieutenant killed in action in Afghanistan, was among the dead interred there.

“I don’t want them,” Trump repeated. “It doesn’t look good for me.”

It turned out that the generals had rules, standards, and expertise, not blind loyalty. The President’s loud complaint to John Kelly one day was typical: “You fucking generals, why can’t you be like the German generals?”

“Which generals?” Kelly asked.

“The German generals in World War II,” Trump responded.

“You do know that they tried to kill Hitler three times and almost pulled it off?” Kelly said.
