When the Romans besieged Syracuse, they were thwarted not by a larger army, but by the futuristic war machines of Archimedes. His catapults, giant claws, and missile launchers created a technological moat that neutralized overwhelming conventional force, showing that superior innovation can be a decisive strategic advantage.

Historically, Russia and China's strategy as continental empires involves avoiding two-front wars and actively destabilizing neighboring states. This creates buffer zones and prevents any single power from becoming a threat on their borders, ensuring their own security through regional instability.

After Cannae, Rome couldn't defeat Hannibal in open battle, so they adopted a strategy of avoidance, creating a stalemate. For a power on the brink of collapse, simply surviving is a form of victory. This prolonged timeline allowed Rome to regroup, rebuild its manpower, and ultimately go on the offensive.

Rome's political and cultural identity was built on an implacable resolve to never accept defeat or disrespect. This dogged determination, which led them to build a navy from scratch and reject peace talks after catastrophic losses, was their ultimate strategic advantage over more conventional powers.

History demonstrates that dominance over seemingly mundane but critical resources is a foundational element of national power. The Roman Empire's control of salt and 19th-century America's pursuit of guano (bird fertilizer) laid the groundwork for their military and economic dominance.

After Cannae, Rome desperately needed manpower, yet the Senate refused Hannibal's offer to ransom its captured soldiers. This seemingly counterintuitive decision was a powerful psychological statement to Hannibal, their allies, and their own people: there would be no negotiation, only total war, regardless of the human cost.

The harsh terms of the First Punic War, which stripped Carthage of territory and imposed a massive indemnity, created deep resentment. This parallels the Treaty of Versailles with Germany, illustrating how overly punitive settlements can sow the seeds of a future war of revenge rather than secure lasting peace.

After his decisive victory at Cannae, Hannibal expected Rome to negotiate terms, as was the norm in ancient warfare. He fatally underestimated their unique, implacable resolve to never capitulate, causing him to miss his window of opportunity to march on the city and enforce a peace.

Instead of being conquered, the Greek city of Syracuse secured its position by becoming a hyper-loyal ally to the new Roman superpower. This "special relationship" mirrors the dynamic between Britain and the US post-WWII, where a former great power ensures its security by being an indispensable partner to the new hegemon.
