“A highly relevant and much-needed historical study . . . One of the best books on the period to have been written.” —The Economist

To the amazement of the public, pundits, and even the policymakers themselves, the ideological and political conflict that endangered the world for half a century came to an end in 1990. How did that happen? What had caused the cold war in the first place, and why did it last as long as it did? To answer these questions, Melvyn P. Leffler homes in on four crucial episodes when American and Soviet leaders considered modulating, avoiding, or ending hostilities and asks why they failed. He then illuminates how Reagan, Bush, and, above all, Gorbachev finally extricated themselves from the policies and mind-sets that had imprisoned their predecessors, and were able to reconfigure Soviet-American relations after decades of confrontation.
