David Wurmser authored 'Tyranny's Ally: America's Failure to Defeat Saddam Hussein,' published by AEI Press in January 1999 (ISBN 0-8447-4074-8, ~166 pages). The book argued that existing U.S. policy toward Iraq would not succeed and advocated regime change. Richard Perle wrote the foreword, reflecting their close mentor-protégé relationship. Wurmser acknowledged Bernard Lewis and Irving Moskowitz as influences and supporters. The book was reviewed by Daniel Pipes in the Middle East Quarterly. It laid the intellectual groundwork for the Iraq War policy Wurmser would later help implement in the Bush administration.
