A rather interesting question I ran across: What did Sun Tzu get wrong?
People like to claim that the Art of War can be applied to practically anything: from running a business, to teaching a class, to raising a family. Even in warfare, the Art of War is still applied to forms of combat that Sun Tzu couldn’t have known would exist (like air combat and submarines). Yet some have argued, that the reason why Sun Tzu is so flexible, is because it’s written in “vague aphorisms” – see Nostradamus and/or various religious texts about the End of the World for example.
Even this being so: there has to be flaws in Sun Tzu teachings – nothing is perfect after all. Hence the question. What in the Art of War has been proven wrong or inferior?
Thinking it over, two things I considered…
Proposed Flaw: Sun Tzu always assumed you’d be facing an enemy that had a “goal” you could deny or seize from them. His teaching always pointed towards achieving a victory. The Art of War seems rather limited, against an enemy who’s willing to destroy themselves to destroy you… or against an enemy who simply seeks absolute destruction of everything (i.e. Mutually Assured Destruction). Worst case scenario: facing against an enemy who seeks nothing more than eternally perpetuating a war for the sake of war itself.
Proposed Inferiority: Sun Tzu underlying teaching is to either start a war with a plan of victory before the war begins, or have a contingency to victory when forced into a conflict. Where Sun Tzu is very quiet on, is the factor of being the defeated. Sun Tzu is all about avoiding defeat. Enter the concept of no matter how much the victor wins, he can never end the war on a positive result. Defeat never achieves victory, because victory was impossible to begin with. The modern War on Terrorism for example… or the Vietnam War (the US won all major conflicts and certainly killed more of the enemy; still lost the entire thing). Both ironically are the same cause: ideology.
