Beginning with the premise that Congress has reasserted its role in U.S. foreign policy, the authors of this book describe, analyze, and evaluate how Congress is exercising its formal and informal powers and responsibilities. Five policy studies examine congressional action in major policy areas, placing Congress's behavior in the institutional and political contexts necessary to an understanding and evaluation of the congressional role; in combination, the studies provide an insightful look at some major developments in recent U.S. foreign policy.
