What Is NATO?
The alliance is bolstering its military deterrent in Europe amid Russia’s invasion of Ukraine and has expanded to include Finland.
Introduction
Founded in 1949 as a bulwark against Soviet aggression, the North Atlantic Treaty Organization (NATO) remains the pillar of U.S.-Europe military cooperation. An expanding bloc of NATO allies has taken on a broad range of missions since the close of the Cold War, many well beyond the Euro-Atlantic region, in countries such as Afghanistan and Libya.
