Washington’s Farewell Address first appeared publicly on September 19, 1796. Washington characterized his address as “the disinterested warnings of a parting friend, who can possibly have no personal motive to bias his counsel.” He warned his countrymen to expect “the batteries of internal and external enemies” to be directed against the country. He exhorted his fellow citizens to preserve their union to gain “greater security from external danger, a less frequent interruption of their peace by foreign nations,” and to avoid civil wars. Anticipating Eisenhower’s warning issued more than a century and a half later, Washington noted the danger of “those overgrown military establishments, which under any form of government are inauspicious to liberty, and which are to be regarded as particularly hostile to republican liberty.” Washington also warned that “love of power and proneness to abuse it . . . predominates in the human heart.” His view of human nature informed his counsel on foreign policy.
