With the end of the Cold War, Europe is more united and freer from the danger of a major war than at any time in modern history. A historically unprecedented and highly desirable European security order is in place. The Dawn of Peace in Europe describes this new "common security order", assesses the alternatives to it, and analyzes the conditions necessary for its continuation. The Dawn of Peace in Europe emphasizes the inescapable truth that the future of this new order depends on Russia and the United States. Mandelbaum assesses how the wrenching transition taking place within Russia might affect its policies toward the arms treaties and toward its neighbors. Finally, he evaluates the durability of the American commitment to an active role in Europe.
