goes clear back to Henry "Scoop" Jackson, longtime Senator from Washington state, and Richard Perle-
The leading light of the neoconservatives was Richard Perle, whom Packer describes as the Iraq war's "impresario, with one degree of separation from everyone who mattered." A partisan of Israel's hard-line Likud Party and a protégé of neocon Democrat Scoop Jackson, Perle recruited two other staunch advocates of Israel, Douglas Feith and Elliott Abrams, to work for Jackson and hawkish Democrat Daniel Patrick Moynihan. Packer writes, "When I half jokingly suggested that the Iraq War began in Scoop Jackson's office, Perle said, 'There's an element of that.'" In 1985, Perle had met and become friends with an Iraqi exile named Ahmad Chalabi. "By the time of the PNAC letter in January 1998, Perle knew exactly how Saddam could be overthrown: Put Ahmad Chalabi at the head of an army of Iraqi insurgents and back him with American military power and cash." --snip----
Perle chaired a study group of eight pro-Likud Americans, including Douglas Feith, who had worked under Perle in the Reagan administration, and David Wurmser, who was the author of the paper produced under the group's auspices ... Afterwards the group was pleased enough with its work to send the paper to the newly elected Israeli prime minister, Benjamin Netanyahu." The paper, "A Clean Break: A New Strategy for Securing the Realm," advocated smashing the Palestinians militarily, removing Saddam from power, and installing a Hashemite king on the Iraq throne.
