Geopolitical Exposure Simulator

Model bilateral tariff shocks, security umbrella withdrawals, and regulatory misalignment to measure an economy’s strategic vulnerability and identify tactical hedge maneuvers.

The Fracture Mechanism

When an assertive "America First" executive policy coincides with a sovereign state that has already detached from its regional single market (such as post-Brexit Britain), the state suffers from a bilateral scissor crisis.

Tariffs on goods shipped to the United States cannot easily be absorbed by pivoting to the European Union due to border sanitary checks, customs declarations, and rules-of-origin audits. Simultaneously, demands for unilateral defense burden-sharing require budgetary reallocation from public services to military deterrence.

Trade Divergence: No transatlantic free trade agreement exists without deep concessions on agricultural standards.
Defense Umbrella Risk: A transactional alliance model forces medium powers to commit at least 2.5% to 3.0% of GDP to sustain baseline deterrence.

Strategic Hedging Levers

To reduce the Strategic Exposure Index below 40, middle-power states must deploy a coordinated tri-pillar defense:

Veterinary & SPS Accords: Negotiating bilateral mutual recognition pacts with the European Union relieves food, chemical, and manufacturing friction without requiring political re-entry.
European Pillar within NATO: Establishing shared joint procurement with France, Germany, and the Nordic group hedges against unilateral US withdrawal.
CPTPP Integration: Expanding preferential zero-tariff market corridors across Indo-Pacific economies to offset US and European slowdowns.
