No, if you were old enough when the Berlin Wall came down and had any interest in world news, you would know about Leningrad and St. Petersburg. I guess if you’re young enough, that’s not part of the zeitgeist for you. I’m kind of surprised you’d heard of Leningrad, to be honest.

For someone with Trump’s upbringing, not knowing this is either dementia or he’s always been an idiot. Given when he was running in 2016 he didn’t know the difference between Hezbollah and Hamas, I would lean toward idiot.
