In times of crisis, the leaders of the military and intelligence communities try to put aside their differences, often many and sundry, and work together for the good of the country. That’s what’s happening today with a remarkable group of retired generals, admirals and spymasters who have signed up for the resistance, telling the president of the United States, in so many words, that he is not a king.

Thirteen former leaders of the Pentagon, the C.I.A. and the F.B.I. have signed an open letter standing foursquare against President Trump, in favor of freedom of speech and, crucially, for the administration of justice. They have served presidents going back to Richard M. Nixon mostly without publicly criticizing the political conduct of a sitting commander in chief — until now.

A bipartisan public statement like this is unprecedented as far as I know, correct?
