The United States has escalated its covert operations against Iran, according to current and former military, intelligence, and congressional sources. They state that Bush sought up to $400 million for these military operations, which were described in a secret Presidential Finding and are designed to destabilize Iran's religious leadership. The covert activities involve support of the minority Ahwazi Arab and Baluchi groups and other dissident organizations. United States Special Operations Forces have been conducting cross-border operations from southern Iraq, with Presidential authorization, since 2007. The scale and the scope of the operations in Iran, which involve the CIA and the Joint Special Operations Command (JSOC), have been significantly expanded in 2008.
