The United States established diplomatic relations with Italy in 1861 following the unification of most of the peninsula into one state. In 1941, Italy — with the other World War II Axis powers Germany and Japan — declared war on the United States. U.S. relations with Italy were reestablished in 1944. Today, the United States and Italy enjoy warm and friendly relations.
Italy is a steadfast and active transatlantic partner, and the U.S. and Italy have sought to foster democratic ideals and international cooperation, especially in areas of strife and civil conflict. The U.S.-Italy partnership is one of our strongest, as Italy is a leader in peacekeeping and military operations around the world. Italy has also worked closely with the United States and others in combating drug trafficking, human trafficking, and terrorism. Over the past two years, Italy has been an early and active partner in the fights against ISIL and Ebola.

Under both the EU treaty’s Right of Establishment and the Friendship, Commerce and Navigation Treaty with the United States, Italy is generally obliged to provide national treatment to U.S. investors established in Italy or in another EU member state. The two countries have enacted an income tax agreement to prevent double taxation.
