The conflict in Ukraine exposed the vulnerability of expensive, "exquisite" military platforms (like tanks) to inexpensive technologies (like drones). This has shifted defense priorities toward cheap, mass-producible, "attritable" systems. This fundamental change in product and economics creates a massive opportunity for startups to innovate outside the traditional defense prime model.

China's showcase of advanced military hardware, like its new aircraft carrier, is primarily a psychological tool. The strategy is to build a military so 'forbiddingly huge' that the US would hesitate to engage, allowing China to achieve goals like reabsorbing Taiwan without fighting. This suggests their focus is on perceived power to deter intervention.

In a world of aging, export-dependent economies like China and Korea, the U.S. is the only large, first-world nation that is a net consumer. This makes access to its market an incredibly powerful negotiating tactic, allowing the U.S. to leverage its consumer base as a tool of foreign policy.

Recognizing Russia's high tolerance for military casualties, Ukraine has shifted its strategy to asymmetric economic warfare. By systematically using long-range drones to attack Russian oil refineries and tankers, Ukraine aims to inflict financial pain where the human cost of war has failed to be a deterrent, creating what they call "the real sanctions."

With the U.S. stepping back from its traditional leadership role, European countries are creating new, direct alliances to ensure their own security. A notable example is the emerging UK-Scandinavia-Baltic-Poland axis, which signals a fundamental shift in the continent's geopolitical architecture away from a singular reliance on Washington.

The promise of asylum is a critical tool for gaining support and intelligence from local collaborators in hostile territories. Rescinding these promises, as threatened by Trump, eliminates this incentive, making it harder to recruit allies and directly putting U.S. service members in greater peril.

After WWII, the U.S. used its naval dominance to guarantee global trade. In exchange for writing its allies' security policies, it allowed open access to its market. This economic "unfairness" was the strategic cost of building a global coalition against the Soviet Union, effectively bribing nations into an alliance.

President Xi Jinping used a phone call with President Trump not just for bilateral issues, but to strategically signal displeasure with Japan's hawkish stance on Taiwan. This "shadow play" diplomacy shows China leveraging its relationship with the U.S. to indirectly manage and warn other nations, making the U.S. a channel for its geopolitical messaging.

Anne Applebaum highlights a disturbing shift where high-stakes foreign policy, like the Ukraine peace plan, is conducted by businesspeople seeking personal financial gain. This mirrors the kleptocratic systems of autocratic states, prioritizing private profit over national or allied interests, and raises questions about who American foreign policy truly serves.
