Washington’s Farewell Address is a letter written by President George Washington to “friends and fellow-citizens” after 20 years of public service to the United States. In his farewell address, Washington exhorted Americans to set aside their violent likes and dislikes of foreign nations, lest they be controlled by their passions: “The nation which indulges toward another an habitual hatred or an habitual fondness is in some degree a slave.” Washington’s remarks have served as an inspiration for American isolationism, and his advice against joining a permanent alliance was heeded for more than a century and a half.
