Speaking rapid-fire with no spot for others to jump into the conversation, Mr. Trump makes everyone a co-conspirator to his preferred set of facts, or delusions. I have felt it — this president building with his words a web of alternative reality and busily wrapping it around all of us in the room.

I must have agreed that he had the largest inauguration crowd in history because I didn’t challenge that. Everyone must agree that he has been treated very unfairly. The web building never stops.

From the private circle of assent, it moves to public displays of personal fealty at places like cabinet meetings. While the entire world is watching, you do what everyone else around the table does — you talk about how amazing the leader is and what an honor it is to be associated with him.

Sure, you notice that Mr. Mattis never actually praises the president, always speaking instead of the honor of representing the men and women of our military. But he’s a special case, right? Former Marine general and all. No way the rest of us could get away with that. So you praise, while the world watches, and the web gets tighter.

Next comes Mr. Trump attacking institutions and values you hold dear — things you have always said must be protected and which you criticized past leaders for not supporting strongly enough. Yet you are silent. Because, after all, what are you supposed to say? He’s the president of the United States.

You feel this happening. It bothers you, at least to some extent. But his outrageous conduct convinces you that you simply must stay, to preserve and protect the people and institutions and values you hold dear. Along with Republican members of Congress, you tell yourself you are too important for this nation to lose, especially now.

You can’t say this out loud — maybe not even to your family — but in a time of emergency, with the nation led by a deeply unethical person, this will be your contribution, your personal sacrifice for America. You are smarter than Donald Trump, and you are playing a long game for your country, so you can pull it off where lesser leaders have failed and gotten fired by tweet.
