Joseph Lepgold's book examines the substance of and rationale for the American defense commitment to Europe between 1960 and 1990, a period marked by change in the U.S. world position, and continues into the 1990s, in light of the recent changes in Europe. Lepgold explores how and why political leaders have adapted to this change. His volume is the analysis of a hegemonic state's foreign policy adaption. His study probes such questions as: If policymakers do not adjust basic policy priorities, what other tradeoffs are made? Do these constitute meaningful patterns? Do commitments resist change or are they context-dependent and supple? The focus of this provocative study is on U.S. policy toward Europe, rather than NATO and its European members.Chapter one of The Declining Hegemon provides the background for Chapters two and three's analytic discussion of policy adaption. It examines four policy debates of the late 1970s and 1980s; these discuss past adaption as well as future choices. These debates question the decline of U.S. power; the future U.S. role in Europe--whether any of the 1950 commitments should be adjusted; and the relationship of foreign policy commitments and resources--whether they should grow and decline in tandem. Chapters four through six provide a decade by decade case study of U.S. policy. The last chapter of Lepgold's timely study draws conclusions and suggests future implications in light of recent developments in Europe.
