Not in Singapore. Nuclear weapons that it was used against Japan, but not cold-war developments in that respect.

Maybe it's because it makes the militaries of non-nuclear states feel small.

I imagine so for most classes would that go into nuclear weapons, it's an easy fun/interesting fact to throw in to keep people interested.

In Venezuela as part of the universal history subject that starts with the Greeks all the way to the modern age, there is no mention of specific bombs but nuclear bombs overall and Hiroshima and Nagasaki. I do remember that at the time they had a picture in the book of a nuclear submarine and I thought, sure it has nuclear weapons therefore a nuclear submarine :)

This is a neat calculator[1]which made the rounds. It has presets like the Tsar Bomba amongst the choices.
