Book excerpt: Originally published in 2007, The Israel Lobby and U.S. Foreign Policy, by John Mearsheimer of the University of Chicago and Stephen M. Walt of Harvard's John F. Kennedy School of Government, provoked both howls of outrage and cheers of gratitude for challenging what had been a taboo issue in America: the impact of the Israel lobby on U.S. foreign policy. A work of major importance, it remains as relevant today as it was in the immediate aftermath of the Israel-Lebanon war of 2006. Mearsheimer and Walt describe in clear and bold terms the remarkable level of material and diplomatic support that the United States provides to Israel and argues that this support cannot be fully explained on either strategic or moral grounds. This exceptional relationship is 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. They provocatively contend that the lobby has a far-reaching impact on America's posture throughout the Middle East―in Iraq, Iran, Lebanon, and toward the Israeli-Palestinian conflict―and the policies it has encouraged are in neither America's national interest nor Israel's long-term interest. The lobby's influence also affects America's relationship with important allies and increases dangers that all states face from global jihadist terror. The publication of The Israel Lobby and U.S. Foreign Policy led to a sea change in how the U.S-Israel relationship was discussed, and continues to be one of the most talked-about books in foreign policy.
