“That afternoon, Mattis called John Kelly, the former Marine general who was then nearing the end of his calamitous run as Trump’s chief of staff. ‘I need an hour with the boss,’ Mattis said. The next day, he met Trump in the Oval Office. Mattis made his case for keeping troops in Syria. Trump rejected his arguments. Thirty minutes into the conversation, Mattis told the president, ‘You’re going to have to get the next secretary of defense to lose to ISIS. I’m not going to do it.’ He handed Trump his resignation letter, a letter that would soon become one of the most famous documents of the Trump presidency thus far.” The Atlantic’s Jeffrey Goldberg on James Mattis. The Man Who Couldn’t Take It Anymore. (There goes my memoir title…) What’s amazing about this and all Mattis interviews is his unwillingness to unload on his former boss, or anyone else. He may have been a great military man. But he’s gonna suck at Twitter.
