Ukrainian president Volodymyr Zelensky, a former comedian, has been diplomatic this week (“Nobody pushed me”) about being pressured by Donald Trump to dig up dirt on his Democratic opponent. In the pulled-together transcript of the two presidents’ phone conversation that took place in July, Mr. Zelensky sounded accommodating and, for all too obvious reasons, at times downright flattering.

But back in Kiev, Block 95, the comedy show that Zelensky created and once starred in, has had plenty to say about Trump. None of it was tactful.
