Are you stupid? I addressed that here:

You are presupposing an already developed rule-based society and that's understandable because one can't even imagine what the opposite would be like apart from devolving into murderous savagery.

Sun Tzu and Nietzsche didn't live in lawless anarchical societies but in highly organized hierarchical societies. Sun Tzu, Machiavelli and modern day intelligence services find ways to game the system and outsmart their opponents. You can't be a great chess player without following the rules of chess.

Wtf geopolitics has to do with anarchy? Warfare is an abstraction. We have warfare because we have societies, that are organized hierarchically the same way an individual is (you have a head, arms, body, etc). In order to get to that level of abstracted aggression we must first observe how aggression is dealt with within society on individual level. Can you defeat a stronger opponent using your cunning? Yes, you can (like King David did for example). But that means in an anarchy you'll always have to be on your guard and ready to defend yourself (or attack) because it's free for all and there's no authority that will prevent or curb aggression.
