The Israel Lobby and U.S. Foreign Policy (a condensed version used the title The Israel Lobby) is the title of a work by John Mearsheimer, the R. Wendell Harrison Distinguished Service Professor of Political Science at the University of Chicago, and Stephen Walt, The Robert and Rene Belfer Professor of International Relations at the Kennedy School of Government at Harvard University, that has gone through several versions from 2002 to 2007. The most recent version is The Israel Lobby and U.S. Foreign Policy, a New York Times Best Seller, published in September 2007 by Farrar, Strauss, and Giroux.
The work's thesis is that "the United States has been willing to set aside its own security in order to advance the interests of another state [Israel]", and that U.S. Middle East policy has driven primarily by domestic politics, especially the "Israel Lobby," defined as a "loose coalition of individuals and organizations who actively work to steer U.S. foreign policy in a pro-Israel direction."
The authors state that the "core of the Lobby" is "American Jews who make a significant effort in their daily lives to bend U.S. foreign policy so that it advances Israel's interests." They note that "not all Jewish-Americans are part of the Lobby," and that "Jewish-Americans also differ on specific Israeli policies."
