Ron Paul: 300 Million Taxpayer Dollars Spent to Undermine Iranian Government

January 20, 2010

“According to current and former military, intelligence, and congressional sources, Congress late last year “agreed to a request from President Bush to fund a major escalation of covert operations against Iran.” These operations, for which the President sought up to $400 million, “were described in a Presidential Finding signed by Bush, and are designed to destabilize the countrys religious leadership…. Clandestine operations against Iran are not new.” U.S. Special Operations Forces “have been conducting cross-border operations from southern Iraq, with Presidential authorization, since last year…. But the scale and the scope of the operations in Iran, which involve the Central Intelligence Agency and the Joint Special Operations Command (JSOC), have now been significantly expanded, according to the current and former officials.””

“On July 7, 2008, Pulitzer Prize winning investigative journalist and author Seymour Hersh wrote an article in the New Yorker stating that the Bush Administration had signed a Presidential Finding authorizing the CIA to begin cross border paramilitary operations from Iraq and Afghanistan into Iran. These operations would be against Quds Force, the commando arm of the Iranian Revolutionary Guard, public and private sector strategic targets, and high-value targets in the Presidents war on terror. Also enrolled to support CIA objectives were the Jundallah, Mujahideen-e-Khalq, known in the West as the M.E.K.,and the Baluchis insurgents.[142] The Finding was focussed on undermining Irans nuclear ambitions and trying to undermine the government through regime change, a person familiar with its contents said, and involved working with opposition groups and passing money.”
