Milley and others around Trump used different methods to handle the unstable president. “You can judge my success or failure on this, but I always tried to use persuasion with the president, not undermine or go around him or slow-roll,” Milley told me. “I would present my argument to him. The president makes decisions, and if the president ordered us to do X, Y, or Z and it was legal, we would do it. If it’s not legal, it’s my job to say it’s illegal, and here’s why it’s illegal. I would emphasize cost and risk of the various courses of action. My job, then and now, is to let the president know what the course of action could be, let them know what the cost is, what the risks and benefits are. And then make a recommendation. That’s what I’ve done under both presidents.”
