George F. Kennan: An American LifeJohn Lewis Gaddis2011

In the late 1940s, George F. Kennan—then a bright but, relatively obscure American diplomat—wrote the "long telegram" and the "X" article. These two documents laid out United States' strategy for "containing" the Soviet Union—a strategy which Kennan himself questioned in later years. Based on exclusive access to Kennan and his archives, this landmark history illuminates a life that both mirrored and shaped the century it spanned.
