The Era of Geopolitical Portfolio Management

The transformation is starkly visible in the Strait of Hormuz. When Iran established an authority to tax shipping, it did more than weaponize a chokepoint; it turned a maritime passage into a revenue stream. Washington’s response—sanctioning the authority to protect the dollar system—was not merely a security move but a counter-pricing of the same asset. This shift is not confined to adversaries. The United States has increasingly treated its own security guarantees as commercial positions, pressing allies like South Korea for massive markups on stationing costs and viewing sovereign land, such as Greenland, as an object for potential acquisition. The 2025 National Security Strategy formalizes this, shifting from the traditional "burden-sharing" model to one of "burden-shifting," where influence is a permanent fact and allies are effectively demoted to tenants.

This new logic treats international law not as a boundary, but as a variable cost. Rules protecting free passage or prohibiting intervention are no longer seen as fixed constraints, but as obstacles to be navigated through legal reinterpretation or economic coercion. While European leaders continue to invoke the vocabulary of the post-1945 order, their actions reveal a profound inability to compete with this new, transactional grammar. As Washington and Tehran treat the world as a portfolio of holdings, Europe remains caught in the middle, struggling to manage its own assets while the very commitments that once guaranteed its security are quietly being liquidated or billed. The postwar order is not collapsing in a single dramatic event; it is being methodically wound down, one repriced alliance at a time.
