America First refers to a policy stance in the United States that generally emphasizes nationalism and non-interventionism. The isolationist approach gained prominence in the interwar period (1918–1939) and was advocated by the America First Committee, a non-interventionist pressure group against the U.S. entry into World War II. Since 2016, an identically named campaign slogan and foreign policy that emphasizes withdrawal from international treaties and organizations has been pursued by the presidential campaigns and administration of Donald Trump. Commentators have derided the policy as "America Alone".
