Trump's Tariff Threats: Weaponizing Trade Against European Allies

Trump's tariff threats against Europe over Greenland risk transatlantic relations and NATO unity.

Background Context

The use of tariffs as a tool of foreign policy has historical precedents, dating back to mercantilist policies of European powers. The Smoot-Hawley Tariff Act of 1930 in the United States, intended to protect domestic industries during the Great Depression, is a notable example of protectionist trade policies with significant global repercussions. This act, which raised tariffs on thousands of imported goods, is widely believed to have exacerbated the economic downturn by reducing international trade. The General Agreement on Tariffs and Trade (GATT), established after World War II, aimed to reduce such trade barriers and promote multilateral trade. The evolution of international trade law and institutions like the World Trade Organization (WTO) reflects ongoing efforts to manage trade disputes and prevent unilateral tariff actions that can destabilize global economic relations.

The Trump administration is threatening to impose tariffs on European countries, escalating to 25% by June 1, 2026, until they agree to U.S. demands regarding Greenland. This action adds to existing tariffs and has been criticized by European leaders. The EU views this as a neo-imperialist tactic and a violation of international law, potentially undermining transatlantic trade agreements. The U.S. Congress has not provided legislative backing for these tariffs, and the administration may face legal challenges. European nations may retaliate with an "anti-coercion instrument" targeting U.S. tech firms. This conflict could weaken NATO and its ability to assist Ukraine.

Latest Developments

Recent years have witnessed a resurgence of protectionist sentiments globally, marked by trade disputes between major economies. The U.S.-China trade war, initiated in 2018, involved the imposition of tariffs on hundreds of billions of dollars' worth of goods, impacting global supply chains and economic growth. The COVID-19 pandemic further exposed vulnerabilities in global trade networks, leading to calls for greater diversification and resilience. The rise of regional trade agreements, such as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), reflects efforts to circumvent multilateral gridlock and foster closer economic ties among participating nations. Future trends suggest a continued tension between protectionist pressures and the need for international cooperation to address global challenges.
