It was here that the Joint Special Operations Command (JSOC) conducted training, beginning in 2005, for members of the Mujahideen-e-Khalq, a dissident Iranian opposition group known in the West as the M.E.K. . . . The M.E.K.'s ties with Western intelligence deepened after the fall of the Iraqi regime in 2003, and JSOC began operating inside Iran in an effort to substantiate the Bush Administration's fears that Iran was building the bomb at one or more secret underground locations. Funds were covertly passed to a number of dissident organizations, for intelligence collection and, ultimately, for anti-regime terrorist activities. Directly, or indirectly, the M.E.K. ended up with resources like arms and intelligence. Some American-supported covert operations continue in Iran today, according to past and present intelligence officials and military consultants.
