While Scipio was a brilliant commander, Rome's ultimate victory stemmed from its institutional advantages. Decades of war had forged a superior, well-drilled infantry, and its vast manpower reserves gave it an edge Carthage, reliant on mercenaries, could not match. Hannibal lost at Zama primarily because he lacked the cavalry that Rome's institutional might could now field against him.

Publius Cornelius Scipio's youthful glamour, popularity with the masses, and adoption of 'Greek-like' customs made him a uniquely effective and beloved commander. However, these same traits bred deep suspicion among the conservative Roman Senate, who viewed his immense personal power as a threat to the Republic, ultimately leading to his political ruin.

The Romans often propagandized the concept of 'Punica Fides' or 'Punic Faith' to portray Carthaginians as uniquely treacherous. Yet, their greatest general, Scipio, used blatant deception by feigning peace negotiations with Sifax and Hasdrubal specifically to learn the layout of their camps before burning them down, highlighting the hypocrisy of wartime rhetoric.

Scipio learned that a lagoon protecting New Carthage periodically became shallow. He timed his attack for this moment, presenting the ebbing water to his troops as a miracle promised by the god Neptune. This divine framing inspired his men and enabled a surprise attack on an unguarded wall.

Despite Carthage being militarily crippled after Hannibal's defeat, the psychological trauma of his invasion persisted in Rome. This "biding fear" was irrational given Carthage's weakness but powerfully shaped Roman policy for generations, ultimately leading to the city's destruction.

The historian Polybius described the Roman sack of New Carthage, noting the practice of killing indiscriminately—including cutting dogs in half—was a deliberate policy. This was not random brutality but a calculated psychological tactic to inspire terror and ensure swift surrenders in future conflicts.

Beyond physical destruction, the Romans committed cultural annihilation. They seized and dispersed Carthage's libraries, which held its rich literary and historical tradition. By preserving only a single farming manual, Rome ensured that future generations would only ever hear the conqueror's version of events.

In a great historical irony, the triumphant Scipio struggled in civilian life, ultimately driven into exile by political rivals jealous of his power. Conversely, the defeated Hannibal successfully transitioned into a civilian leader in Carthage, enacting popular democratic and financial reforms that made him beloved by the people, though hated by the aristocracy.

Roman senator Cato was horrified to find Carthage thriving economically decades after its defeat. He perceived this prosperity—rich hinterlands, upgraded harbors, and stockpiled timber—as a direct threat, proving that a rival's economic resurgence can be a powerful catalyst for preemptive war.
