Part of a larger project, "The U.S. and the USSR: Choices for the 21st Century," that is aimed at developing curricular materials for use at the secondary, undergraduate, and adult education levels, this book helps high school students to think through some of the complex issues surrounding U.S.-Soviet relations and the nuclear arms race as the United States enters the twenty-first century. By presenting four alternative "futures" for U.S.-Soviet relations in 2010, this book helps students consider what policies the United States should follow in the years ahead. The four images presented of the United States in the year 2010 are called: (1) "The U.S. Gains the Upper Hand"; (2) "Eliminate the Nuclear Threat, Compete Otherwise"; (3) "Cooperative Problem Solving"; and (4) "Defend Only North America." Students also are asked to create a "Future 5." The book also provides a history of U.S.-Soviet relations. A glossary, with small maps, is included. (AS)
