I highly recommend Sir Lawrence Freedman's Strategy: A History. It debates what strategy is, exactly, by moving from game theory, business, and war studies. It does this in a lengthy 630 page treatise, but does not stay away from Foucault and Pareto's contributions. I feel like I knew a lot, as a student of strategy, but the book definitely treats it well. The book also starts with the Iliad and moves forward, so no student of history will be left with dissatisfaction.
It used rudimentary diagrams of the Prisoner's Dilemma and explained the Nash Equilibrium as well as I have understood it. I am not mathematician, of course. Yet, I highly recommend this book.
