In the Treaty of Versailles and the SALT II Treaty, years of painstaking diplomatic effort were lost when the United States Senate refused to provide its consent to ratification. This book provides a comparative assessment of executive-congressional relations and the arms control treaty ratification process. A team of historians, political scientists and policy analysts looks at seven case studies, from Versailles to the INF Treaty, to explore the myriad ways to win and lose treaty ratification battles. This book constitutes a marriage of scholarship and public policy. Michael Krepon is the editor of "Commercial Observation Satellites and International Security". Dan Caldwell has also written "The Dynamics of Domestic Politics and Arms Control: The SALT II Treaty Ratification Debate".
