This book describes the clandestine missions that were defining moments in the evolution of the Mossad, including its pursuit of the Black September terrorists who murdered Israeli athletes at the 1972 Olympic Games, its acquisition on the high seas of yellowcake uranium for Israel's undeclared nuclear weapons program, and its role in bringing to justice Nazi war criminal Adolf Eichmann. The agency's more questionable deeds are also covered, among them the assassination of civilian scientists associated with Iraq's nuclear energy program and the abduction of Israeli citizen Mordechai Vanunu, who, like Edward Snowden, has been variously depicted as a principled whistleblower and an unscrupulous traitor. Taken together, the missions discussed in this volume illustrate the Mossad's character, creativity and courage, while acknowledging the problematical moral dimensions of its operations.
