In this volume I show how Reagan foiled the Soviet drive for strategic weapons superiority with a complex, high technology weapons buildup and a surprise shift to strategic defense, inaugurating a fundmental change in the national security equation. He neutralized the Soviet attempt to dominate the Eurasian landmass with the SS-20 missile by deploying the Pershing II/cruise missile package to Western Europe. And he blocked the Soviet drive to shift Iran into its orbit thereby preserving the secure flow of oil to the west and opening the door to an improvement of reltions with Iran. Recognizing that the Soviet Union was overextended, fueling revolutionary movements on four continents and deeply mired in Afghanistan, the president raised the costs of competition for the Soviet economy already laboring under the heavy burden large-scale military expenditures. He worked for reduced energy prices, reducing Soviet hard-currency earnings, while at the same time blocking the transfer of high technology upon which the Soviet Union depended to remain competitive with the United States. By the middle of 1984 the Soviet leadership concluded that its strategy had failed and would have to be changed.
