But more often, proximity to an amoral leader reveals something depressing. I think that’s at least part of what we’ve seen with Bill Barr and Rod Rosenstein. Accomplished people lacking inner strength can’t resist the compromises necessary to survive Mr. Trump and that adds up to something they will never recover from. It takes character like Mr. Mattis’s to avoid the damage, because Mr. Trump eats your soul in small bites.
It starts with your sitting silent while he lies, both in public and private, making you complicit by your silence. In meetings with him, his assertions about what “everyone thinks” and what is “obviously true” wash over you, unchallenged, as they did at our private dinner on Jan. 27, 2017, because he’s the president and he rarely stops talking. As a result, Mr. Trump pulls all of those present into a silent circle of assent.
