Yes, there is this delusion that the majority of the world should know and care about the Holocaust for instance.

They don't and nor should they. It's a Western centric concept and for most of the world were it has no relevance it's hard to understand.

(You might argue all incidents like that should be taught in all schools, but until the West starts they can't expect anyone else to care about their bugbears)

I feel like history classes focus too much on inane specifics and on chronology. I would have preferred general topics, and an overview of worldwide events that qualify for those topics.

For example -

Genocides: The holocaust, Rwandan genocide, Armenien genocide, etc.

Empires: British, Mongol, Roman etc.

Wars: WWII, WW1, Mongol Wars, etc.

Fastest expanding empires, Most peaceful periods, Most scientifically productive periods, etc.

I think this eliminates much of what you learn from history when you study it. Knowing what lead into WW1 and WW2 spanned for decades before, and were much more important than learning the actual facts of the war. History isn't really the study of what happened, rather it's the study of the consequences of what happened. Going in chronological order gives you a sense of what to expect based off what is happening.

This is worse, this will present the subject as a stand alone manifestation, instead as a part of a continuum.

I was actually surprised at how much time my elementary school curriculum spent on the Holocaust (as in multiple weeks).

Never heard about Armenian and Rwandan genocides until college.
