Sun Tzu is so fucking funny to me because for his time he was legitimately a brilliant tactician but a bunch of his insight is shit like "if you think you might lose, avoid doing that", "being outnumbered is bad generally", and "consider lying."
My personal favourite is his lengthy lecture on the subject of Supplies Being Very Important I Cannot Stress Enough The Importance Of Protecting Your Supply Lines But Also Supply Lines Are Expensive As Shit So Steal The Enemy’s Supplies At Every Opportunity.
One of the more important things to consider about any historical work is the audience it was published for. The Art Of War was aimed at fancy nobles high on philosophy with little practical military experience who were nonetheless leading armies.
Sun Tzu, after desperatly trying to explain extremely basic logic to a bunch of upper-class twits, basically sat down and wrote the most elaborate "As per my last email" ever
I was trying to explain The Art of War to my mother recently, and I referenced The Prince, in that Machiavelli wrote The Prince both as a genuine guide on good governance* (as he saw it) but in its historical context it may also be understood as an acerbic political commentary on the issues he saw both with Italy in general and the Medicis who had exiled him specifically.
Some of Machiavelli's advice also seems blindingly obvious - "don't use mercenaries if you can avoid it, and if you can't avoid it, most certainly don't refuse to pay them," "maintaining a balanced budget is a good idea," "if you make alliances, honour them" etc. etc. - but if you look at what was going on at the time he was alive, you can see why he might feel it necessary to plainly state these things.
If stuff in a very famous book seems weird or obvious it's probably indicating that you should consider the historical context in which such a seemingly obvious thing needed to be said.
