Spain joined the North Atlantic Treaty Organization (NATO) in 1982. In addition to U.S. and Spanish cooperation in NATO, defense and security relations between the two countries are regulated by the Mutual Defense Assistance Agreement and the Agreement on Defense Cooperation. Under this agreement, Spain has authorized the United States to use certain facilities at Spanish military installations. In 2012 and 2015, Spain and the United States amended this agreement to permit the basing of additional U.S. personnel and equipment at bases in southern Spain. Spain is an active participant in the Coalition to Defeat ISIS, with over 500 personnel deployed in Iraq in 2020 to support the training of Iraqi security forces.

Bilateral Economic Relations
Spain’s accession to the European Union (EU) in 1986 required the country to open its economy to trade and investment, modernize its industrial base, improve infrastructure, and revise economic legislation to conform to EU guidelines. Spain is now the fifth-largest economy in the EU and the fourth-largest economy in the Eurozone. Spain and the United States have a friendship, navigation, and commerce treaty as well as a bilateral taxation treaty, the implementation of which may stem the practice of many U.S. companies channeling their Spanish investments and operations through third countries.
