A Brezhnev-era joke asked whether it was a crime to say that the party chairman was an idiot. The answer was yes, because it’s a state secret. For those who miss Soviet-era humor, French President Emmanuel Macron has provided some consolation, by firing the French ambassador to Budapest for observing in a private memorandum that the president of Hungary is not an anti-Semite. Evidently that is a state secret in France.
