It’s obviously not meant to be an exhaustive list of such books, which would be impossible. And any such list on the internet is just an opening for an argument.
What? War and Peace is relatively long but not particularly challenging to read, at least for the time period it was made for and compared to the other books listed.
But then again, I really loved the philosophical ramblings on history and leadership and how much Napoleon sucked. Honestly feel it should be required reading for anyone in a leadership position. But then again, if you just want to read the story, the parts can be easily skipped.
Granted you need to have some baseline knowledge of Russian culture and with some philosophical concepts like materialism to really grok it, I guess. I think hard to read can be very subjective anyway depending heavily on what books one have read before and general background.
