Trump Threatens Trade War with Spain Over NATO and Iran Policy

U.S. President Donald Trump announced on Tuesday, March 3, 2026, his intention to cut off all trade with Spain following disputes over military base access, NATO defense spending commitments and Spain’s criticism of U.S. Policy toward Iran. The move escalates tensions between the two nations and raises questions about the future of the U.S.-Spain relationship.

Dispute Over Military Base Access

The immediate trigger for Trump’s announcement was Spain’s refusal to allow the U.S. Military to use Spanish bases – Rota and Moron – for flights related to a military offensive against Iran. Trump characterized Spain as a “terrible” ally for this decision, stating, “They have nothing that we need,” and questioning the country’s leadership.

NATO Spending and Commitments

The dispute also stems from ongoing disagreements over NATO defense spending. Trump has repeatedly criticized Spain for not meeting the alliance’s target of 2% of GDP, and more recently, for refusing to commit to a proposed increase to 5%. He referenced a previous threat made at the NATO summit in The Hague last June regarding tariffs over Spain’s defense spending reluctance. German Chancellor Friedrich Merz, alongside Trump at a press conference, echoed the call for Spain to meet NATO spending objectives, suggesting a commitment to 3% or 5%.

Spain’s Response and EU Trade Policy

The Spanish government swiftly responded, asserting its commitment to NATO and its role as a key member of the alliance. However, it also emphasized that trade policy falls under the jurisdiction of the European Union, not individual member states. A government statement highlighted Spain’s position as a major exporting power within the EU and a reliable trading partner for 195 countries, including the United States. Madrid expressed confidence in its ability to mitigate any potential impact from U.S. Trade restrictions, diversify supply chains, and support affected sectors.

Legal and International Considerations

Spain’s government indicated that any changes to trade relations with the U.S. Would need to comply with international law and existing EU-U.S. Agreements. They expressed hope that Trump’s threat would not materialize, drawing parallels to previous warnings from the U.S. President. Treasury Secretary Scott Bessent reportedly agreed with Trump’s assessment that an embargo on Spain was legally permissible, citing a recent Supreme Court decision affirming the president’s authority to impose tariffs.

Criticism of U.S. Iran Policy

The tensions were further exacerbated by Spanish Prime Minister Pedro Sánchez’s criticism of the U.S.-Israeli action against Iran, deeming it “unjustifiable, dangerous and outside of international law.”

Broader Implications

Trump’s announcement raises concerns about the stability of transatlantic relations and the future of U.S. Alliances. The situation also comes amid ongoing debates about burden-sharing within NATO and the appropriate response to geopolitical challenges, such as the conflict in Iran. Prime Minister Sánchez is scheduled to address the nation on Wednesday, March 4, 2026, at 9 a.m. From La Moncloa.
