The Deadliest Lies: The Israel Lobby and the Myth of Jewish Control is a 2007 book authored by Abraham H. Foxman, who served as the national director of the Anti-Defamation League (ADL). The book serves as a direct rebuttal to the controversial 2007 work The Israel Lobby and U.S. Foreign Policy by John Mearsheimer and Stephen Walt, which argued that pro-Israel advocacy groups exert undue influence on American foreign policy. Foxman critiques the conspiracy theories about Jewish influence embedded in such claims, portraying them as modern manifestations of age-old antisemitic tropes about Jewish control and power. He defends the legitimacy of pro-Israel lobbying as standard democratic advocacy while highlighting the dangers of narratives that demonize Jewish solidarity and influence.

In the book, Foxman addresses public figures and scholars, including Jimmy Carter and the authors of The Israel Lobby, who he believes lend credibility to these harmful stereotypes under the guise of academic discourse. He argues that the resurgence of such ideas coincides with a troubling decline in global Jewish unity, which he sees as essential for countering contemporary threats like antisemitism and terrorism. Foxman's writing style is described as lively and engaging, aiming to diagnose the 'sickness' of these conspiracy theories and warn of their potential to incite further prejudice and division.

Published by Palgrave Macmillan, the book emphasizes human rights advocacy and the ADL's mission to combat bigotry. It has been noted for its role in defending Jewish community interests and challenging what Foxman views as veiled antisemitism in political criticism of Israel. While praised by some for its passionate defense, it has also faced criticism for potentially conflating legitimate policy debate with conspiracy mongering.
