Undeclared Wars with Israel examines a spectrum of antagonism by the East German government and West German radical leftist organizations - ranging from hostile propaganda and diplomacy to military support for Israel's Arab armed adversaries - from 1967 to the end of the Cold War in 1989. This period encompasses the Six-Day War (1967), the Yom Kippur War (1973), Israel's invasion of Lebanon in 1982, and an ongoing campaign of terrorism waged by the Palestine Liberation Organization against Israeli civilians. This book provides new insights into the West German radicals who collaborated in 'actions' with Palestinian terrorist groups, and confirms that East Germany, along with others in the Soviet Bloc, had a much greater impact on the conflict in the Middle East than has been generally known. A historian who has written extensively on Nazi Germany and the Holocaust, Jeffrey Herf now offers a new chapter in this long, sad history.

'An excellent review of the growing hostility of the German left towards Israel during the last fifty years.'

Walter Laqueur

'A critical book at a critical moment. By examining the Cold War politics of the German left toward Israel, Jeffrey Herf unlocks the origins of contemporary global strategies aimed at Israel’s delegitimization, as well as the fusion of anti-Zionism with antisemitism. A remarkable array of sources, from secret police and intelligence files to acrimonious UN debates, makes this book especially authoritative.'

Norman J. W. Goda - author of Tales from Spandau: Nazi Criminals and the Cold War

'Jeffrey Herf's Undeclared Wars with Israel greatly enhances our understanding of the shadowy proxy wars fought in the Cold War's closing decades. It commendably sheds new light on the communist bloc's efforts to covertly undermine Israel and diminish western influence in the Middle East. Herf systematically documents both the arms transfers and clandestine support given to an international terrorist campaign that unrelentingly targeted Israel but also de-stabilized the region and convulsed the globe.'

Professor Bruce Hoffman - Director, Center for Security Studies, Georgetown University, Washington DC

'Jeffrey Herf's superb book recounts a deeply troubling episode of the Cold War. He shows how East Germany's Communist regime waged a prolonged, violent campaign against Israel, often with sinister anti-Semitic overtones. Unlike the democratic government in West Germany, which took many important steps to atone for the Holocaust and other Nazi crimes, the East German Communists refused to accept any responsibility for the Holocaust and instead provided arms, training, and support to those who wanted to kill Jews and wipe Israel off the map.'

Mark Kramer - Director, Cold War Studies, and Senior Fellow, Davis Center for Russian and Eurasian Studies, Harvard University, Massachusetts

'Voluminously documented, [Herf's] new study is the most comprehensive inventory yet of how much of what - treaties, speeches, editorials, state visits, General Assembly votes, military and technical training, academic exchanges, and even enumerated bullets - East Germany did to make Arab friends and influence Arab people. From the late 1960s to the memorable autumn of 1989, a parade of Arab leaders, military and technical delegations, scientists, and aspiring revolutionaries visited East Germany for acclaim, legitimacy, all possible instruments of both hard and soft power, and even access to the West via East Berlin. Meanwhile East Germany offered a home away from home to fugitive West German lefties.'

'This groundbreaking book demands to be read, for its advances a deeper understanding of the Cold War period and the Leftist war on Israel. If Germany is serious about grappling with its past, a German publisher will swiftly translate Herf's comprehensive study.'

‘Jeffrey Herf shines a searchlight into dark episodes into Germany’s troubled past.’

'Herf has mined numerous important archives and German-language materials … a landmark of scholarship on this understudied and tragic episode of German-Jewish relations.'

'Jeffrey Herf has produced not only a prodigiously researched indictment but also a timely reminder. As he writes at the very end of his book, although they have been defeated, the communists and radical leftists in Germany ‘left behind a toxic ideological brew. Their distortions about the history of the state of Israel, their extensive use of terrorism, and their justifications for it have cast a long and destructive shadow over politics and political culture in the Middle East, in Germany, and around the world.'

Allan Arkush Source: Jewish Review of Books

'Herf has written an important study of a difficult and multidimensional chapter in the history of Germans and Jews, interweaving political and military history in East Germany, the rise and self-immolation of the New Left in the West, the vicissitudes of Arab and Palestinian terrorism, and the efforts of Jews, in Israel and in Germany, to survive.'

Russell A. Berman Source: Holocaust and Genocide Studies

'Herf has written a readable and informative study of the GDR’s position toward Israel, which adds a new chapter to the research of the history of German-Israeli relations. It is based on a large corpus of primary sources and is methodologically well composed. Undeclared Wars with Israel will be a useful source for those studying German and Israeli history, the history of the Arab-Israeli conflict, the history of international relations, and the history of the European left.'
