The NEOCONS : One Tentacle of the Jewish Lobby in the US

One of the key tenets of neoconservatism is the vigorous support for Israel and a tendency to favour its more hardline elements. It is the Jewish Americans who form the core of the neoconservative movement which is a microcosm of the larger pro-Israel movement. Neoconservatism is also widely supported by Christian Zionists which is a subset of the politically-inclined Christian Right.
Some of the notable neoconservatives (or neocons) include Elliot Abrams, Kenneth Adelman, William Bennett, John Bolton, Douglas Feith, Jeane Kirkpatrick (dec.), I. Lewis Libby, Richard Perle, Paul Wolfowitz, James Woolsey, David Wurmser, Robert Bartley, David Brooks, Charles Krauthammer, William Kristol, Bret Stephens, Norman Podhoretz, Fouad Ajami, Eliot Cohen, Aaron Friedberg, Bernard Lewis, Ruth Wedgwood, Max Boot, David Frum, Reuel Marc Gerecht, Robert Kagan, Michael Ledeen, Joshua Muravchik, Daniel Pipes, Danielle Pletka, Michael Rubin, and Meyrav Wurmser.
The leading neoconservative magazines & newspapers are the Commentary, the New York Sun, the Wall Street Journal and the Weekly Standard. The think-tanks and advocacy groups that are closely aligned to the neocons are the American Enterprise Institute (AEI), the Centre for Security Policy (CSP), the Heritage Foundation, the Hudson Institute, the Foundation for Defense of Democracies (FDD), the American Israel Public Affairs Committee (AIPAC), the Jewish Institute for National Security Affairs (JINSA), the Middle East Forum (MEF), the Project for a New American Century (PNAC), the Washington Institute for Near East Policy (WINEP), and to a lesser extent, the Bradley Foundation and the Henry Jackson Society.
The neocons occupy influential positions at a variety of organisations and institutions and have been prominent in shaping the Bush Administration's unilateralist foreign policy, and especially the ill-fated decision to invade Iraq in March, 2003.
Neoconservatism is essentially a political ideology which mostly extols the virtues of US hegemony, and sometimes even the idea of an American Empire, and they believe US power should be used to encourage the spread of (western) democracy and discourage potential rivals from even trying to compete with the United States.
