In March 2006, in the London Review of Books, John Mearsheimer of the University of Chicago and Stephen Walt of Harvard's John F. Kennedy School of Government published one of the most hotly debated articles in recent memory. "The Israel Lobby" provoked both howls of outrage and cheers of gratitude for breaking the silence surrounding the most taboo political question: What is the impact of the Israel lobby on U.S. foreign policy—and is it in the national interest?

Including new material on recent developments, as well as deepening and expanding on the arguments presented in their original article, Mearsheimer and Walt describe the remarkable level of material and diplomatic support that the United States provides to Israel and contend that this support cannot be fully explained on either strategic or moral grounds. This close alliance is, they argue, due largely to the political influence of a loose coalition of individuals and organizations that actively work to shape U.S. foreign policy in a pro-Israel direction.

Mearsheimer and Walt provocatively conclude that the policies and positions adopted by the U.S. as a result are in neither America's national interest nor Israel's long-term interest—and they have far-reaching implications around the world, from Iraq, Iran, and Lebanon to America's relationships with its allies, to the spread of global jihadist terror.

Writing in The New York Review of Books, Michael Massing declared, "Not since Foreign Affairs magazine published Samuel Huntington's 'The Clash of Civilizations' in 1993 has an academic essay detonated with such force."  Mearsheimer and Walt's argument has been widely—and sometimes heatedly—covered in the national and international press and by opinion pages. The publication of The Israel Lobby and U.S. Foreign Policy is certain to expand the debate and to be one of the most talked about books of the year.
