"[E]ternal vigilance is the price of liberty,"...We see ourselves as a city on the hill, a stronghold for democracy, looking for threats from abroad.… - Timothy Snyder

Personally about Mr. Trump, it tells me that his desire to protect himself, his ego, his appearance, his sense of being right, is bottomless, because if there's anything that you should hold back from doing, it's from punishing someone like Lt. Colonel Vindman. ...[I]t calls up to me... a memory of what s are like, because that... is what is happening. People who refuse to tow the line, a line of fiction. A line which said that Ukraine plotted against the United States, and not Russia. A line that said a server was in Ukraine, which has never been the case. A line which said that Ukraine was corrupting us, when were trying to corrupt Ukraine, in fact, in the Trump administration. A line which was false. A set of statements which were clearly false and which Republican senators also know to be false. That you don't follow a line like that, and then get purged. That's what happens in... totalitarian systems.

We might be tempted to think that our democratic heritage automatically protects us from such threats. This is a misguided reflex. Our own tradition demands that we examine history to understand the deep sources of tyranny, and to consider the proper responses to it. We are no wiser than the Europeans who saw democracy yield to fascism, Nazism, or communism in the twentieth century. Our one advantage is that we might learn from their experience. Now is a good time to do so.

Professional ethics must guide us precisely when we are told that the situation is exceptional. Then there is no such thing as “just following orders.” If members of the professions confuse their specific ethics with the emotions of the moment, however, they can find themselves saying and doing things that they might previously have thought unimaginable.
