Although less remembered than some of his colleagues, American diplomat Loy Henderson often stood in the thick of controversy during his distinguished forty-year career. An uncompromising and frequently contentious anti-communist, Henderson left his unmistakable imprint on many crucial policy decisions, ranging from the delay of recognition of the Soviet Union in the 1920s and 1930s, to the Truman doctrine of the 1940s, to the overthrow of the Mosadeq government of Iran during the 1950s. Now, in this fascinating biography, H.W. Brands recounts Loy Henderson's far-flung diplomatic career and, in doing so, opens a window onto the entire Cold War Era. Henderson's ascent to a position of major influence among American foreign-policy makers paralleled the rise of the United States to unprecedented influence in global affairs, with anti-communism providing much of the impetus and rationale in both cases. Henderson acquired his life-long preoccupation with the communist menace--a preoccupation that reflected his psychological make-up and personal history, as well as the objective actions of Soviet leaders--in Moscow in the mid-1930s, when he served with the first group of American diplomats posted to the Soviet Union. He witnessed directly the terror and brutality of the Stalinist system, and he spent the rest of his career agitating against anything that might facilitate the spread of that system. Henderson's refusal to compromise his convictions threw him repeatedly into conflict with his superiors--as during World War II, when he warned that Soviet cooperation was a cynical and passing phenomenon, and in the fight over American support for the creation of Israel, when he predicted that American backing for the Zionists would alienate the Arabs and lay the Middle East open to Soviet penetration. In each instance, Henderson's outspokenness led to professional exile; but each time he succeeded in working his way back to the center of the decision-making process. Brands's compelling narrative captures the drama of some of the key developments in international politics in the twentieth century. We find Henderson sifting the rubble of World War I in Eastern Europe, taking a front-row seat at the Moscow purge trials, assessing the future of awakening Iraq during World War II, orchestrating America's cold-war assumption of Britain's imperial burden in Greece and Turkey, challenging the neutralism of India's Nehru during the Korean war, and engineering the restoration of the shah of Iran. Brands's tale, based on Henderson's personal and official papers, and on the papers and recollections of many of Henderson's associates, is more than a biography; it is a chronicle of the most eventful period in recent American and world history, told through the life of one of the individuals who helped make the period so dramatic.
