First, I must explain what the Project for The New American Century (PNAC) is. The PNAC is a relatively new, rightwing, Republican think-tank that was started in the 1990's in Washington D.C.. The PNAC was and is made up of entirely Republicans, many of them from the Reagan and Bush41 administrations. They are also called "Neo Conservatives" or Neo-cons" in the general media. These "Neo-Cons" from the PNAC believe in aggressive use of U.S. military force, unilateralism, and have a strong disdain for the United Nations and other international organizations.
Some the more famous members of the PNAC:
Many of the top thinkers at the PNAC are conservative Jews who are strongly pro-Israel and anti-Arab. These folks would like to radically alter the Middle East.
