The Ukrainian conflict demonstrates the power of a fast, iterative cycle: deploy technology, see if it works, and adapt quickly. This agile approach, common in startups but alien to traditional defense, is essential for the U.S. to maintain its technological edge and avoid being outpaced.

Unlike China's vast, easily unified plains, Europe's geography of mountains and rivers created natural barriers. This prevented a single empire from dominating and instead fostered centuries of intense competition between states. This constant conflict spurred rapid technological and military innovation, ultimately leading to European dominance.

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.

Despite a poor formal education, Winston Churchill consistently grasped the strategic potential of new technologies like the tank, radar, and nuclear weapons. His innate sense for the "realities of these things" allowed him to champion innovations that established experts and military leaders initially dismissed or misunderstood.

Openness is a tool for dominance, not just a moral virtue. The Romans became powerful by being strategically tolerant, quickly abandoning their own methods when they found better ones elsewhere. This allowed them to constantly upgrade their military, technology, and knowledge from conquered peoples.

The long-held belief that a complex codebase provides a durable competitive advantage is becoming obsolete due to AI. As software becomes easier to replicate, defensibility shifts away from the technology itself and back toward classic business moats like network effects, brand reputation, and deep industry integration.

Military technology often evolves incrementally. However, a breakthrough like the Maxim machine gun can suddenly render centuries of established doctrine—such as the drilled infantry charge—completely obsolete. This creates a strategic crisis that forces an equally radical technological and tactical response, like the tank.

Instead of matching China's manufacturing output one-for-one, the US should pursue an asymmetric strategy. This involves leveraging American ingenuity to create superior, low-cost countermeasures, like undefeatable missiles, that neutralize a volume advantage.

Nuclear submarines can stay submerged for 90 days, limited by their food supply, not energy. The onboard nuclear reactor provides limitless power to convert seawater into breathable air and water, demonstrating how a single technological leap can completely redefine a system's constraints.
