Jeffrey Goldberg at The Atlantic:
The subject of North Korea represented my best chance to wrench a direct answer from Mattis. I had collected some of Trump’s more repellent tweets, and read aloud the one that I thought might overwhelm his defenses. It is a tweet almost without peer in the canon:
North Korea fired off some small weapons, which disturbed some of my people, and others, but not me. I have confidence that Chairman Kim will keep his promise to me, & also smiled when he called Swampman Joe Biden a low IQ individual, & worse. Perhaps that’s sending me a signal?— Donald J.

Mattis looked at his hands. Finally he said, “Any Marine general or any other senior servant of the people of the United States would find that, to use a mild euphemism, counterproductive and beneath the dignity of the presidency.”
He went on, “Let me put it this way. I’ve written an entire book built on the principles of respecting your troops, respecting each other, respecting your allies. Isn’t it pretty obvious how I would feel about something like that?”
