The Kazakh, Ukrainian and Armenian presidents were all able to give pretty good answers in the circumstances, recognising the joke, taking it as a joke but still managing to sound reasonably technically competent. I can't imagine many Western leaders responding in such an "in the know" way to what seems like a fairly obscure meme.
It is easy to imagine. Press team picks a question, googles or asks friends, then puts the answer on teleprompter or on a sheet of paper. The president has just one job — to read it with confidence in front of the camera when asked.
The president who would be able to do it by themselves has not yet born on this planet.
