Based on recently declassified documents in the Carter Library, materials not previously noted in the Vance papers, and a wide variety of interviews, Betty Glad's An Outsider in the White House is a rich and nuanced depiction of the relationship between policy and character. It is also a poignant history of damaged ideals. Carter's absolute commitment to human rights foundered on what were seen as national security interests. New data from the archives reveal how Carter's government sought the aid of Pope John Paul II to undercut the human-rights efforts of the El Salvadoran Archbishop Oscar Romero. A moralistic approach toward the Soviet Union undermined Carter's early desire to reduce East-West conflicts and cut nuclear arms. As a result, by 1980 the Strategic Arms Limitation Treaty (SALT) was in limbo, and a nuclear counterforce doctrine had been adopted.

Near the end of Carter's single term in office Vance stepped down as secretary of state, in part because Brzezinski's "muscular diplomacy" had come to dominate Carter's foreign policy. When Vance's successor, Edmund Muskie, took over, the State Department was reduced to implementing policies made by Brzezinski and his allies. For Carter, the rivalry for influence in the White House was concluded and the results, as Glad shows, were a mixed record and an uncertain presidential legacy.
