The authors of this collection of essays examine such issues as devising an effective strategy against the proliferation of nuclear weapons, coping with the spread of space technology, and curbing Iran and North Korea's strategic programs. The contributors address these challenges and their implications for U.S. policy in the book's five divisions. Part 1 explores how best to reform existing nonproliferation efforts. Part 2 considers new high-leverage systems likely to threaten the United States in the near future. Parts 3 and 4 focus on two new truculent proliferators—North Korea and Iran. Part 5 discusses the need to develop a long-term diplomatic, political, economic, and military strategy against proliferation. Fighting Proliferation places itself in the mainstream of opposition to proliferation and the search for practical, policy-relevant approaches to dealing with it.
