- Hamilcar Barca raised his three sons Hannibal, Hazdrubal and Mago, to hate Rome from their early childhood, going so far as to make them swear an oath of eternal enmity (according to Livy). While competition in a free marketplace is much more rational and impersonal, the conflict between Hannibal and Rome was very much rooted in deep ideological hatred.
- Hannibal's strategy was to separate Rome from its allies in the Italian peninsula, which is why he did not march on Rome after Cannae. Perhaps there are realistic business strategy where the aim is to systematically dismantle any means of support that a competitor has, but they aren't well represented in the examples given.
- Quintus Fabius was originally known as Cunctator ("the delayer") as an epithet, and only much later as an agnomen, partly due to his policy that they would not negotiate with Hannibal to exchange prisoners of war. Not only that, it was illegal for the family of a captured soldier to independently negotiate for their family member's release. It's hard to understand what public opinion was like at that time, and the most reliable source (Polybius) was a Roman prisoner-of-war himself!
- The Fabian strategy as it might be applied to management wisdom would not realistically be a "delaying strategy" (i.e. wait for your competitors to run out of resources while trying to limit them as much as possible) but rather a strategy of optimizing your workforce to be more nimble and self-sufficient. Rather than have one large army that represented a single point of failure, the Fabian strategy was to have many small armies that continuously harassed Hannibal's forces for many years.
If the author of this post is reading - I love your writing style and don't intend for this to be interpreted as criticism, I just thought it was an interesting analogy that warranted further exploration.
