A number of analyses of American foreign policy suggest that over the course of some two hundred years there have been two distinct themes in the American diplomatic experience. These can be labeled the realist and idealist. At various times first one and then the other appears to have assumed at least a temporary predominance in American thinking and diplomatic activity. The classic statement of the realist approach still remains that which was offered by John Quincy Adams in 1823 in response to pressure on the United States to intervene to assist the Greeks in their war of independence against the Ottoman Turks. “Wherever the flag of freedom may be unfurled,” remarked Adams, the heartfelt sentiments and sympathy of the American people go out to those struggling for freedom. On the other hand, the United States should and could not assume a direct responsibility in such struggles. In Adams' vivid phrase, America “goes not abroad in search of monsters to destroy.” The Adamsonian or realist approach to American foreign policy then posits that altruistic or moral concerns are essentially irrelevant to the real objectives of a sound national diplomacy, which are the protection of one's own sovereignty and political and economic well-being. In our external relations, then, the focus ultimately must be on power considerations, the development of our strictly personal national interests.
