Intelligence agencies spend huge sums of money to collect and analyze vast quantities of national security data for their political leaders. How well is this intelligence analyzed, how often is it acted on by policymakers, and does it have a positive or negative effect on decision making? Drawing on declassified documents, interviews with intelligence veterans and policymakers, and other sources, The Image of the Enemy breaks new ground as it examines how seven countries analyzed and used intelligence to shape their understanding of their main adversary. The cases in the book include the Soviet Union's analysis of the United States (and vice versa), East Germany's analysis of West Germany (and vice versa), British intelligence in the early years of the Troubles in Northern Ireland, Israeli intelligence about the Palestinians, Pakistani intelligence on India, and US intelligence about Islamist terrorists. These rivalries provide rich case studies for scholars and offer today's analysts and policymakers the opportunity to closely evaluate past successes and failures in intelligence analysis and the best ways to give information support to policymakers. Using these lessons from the past, they can move forward to improve analysis of current adversaries and future threats.
