But a vast expansion of the CIA, combined with the ongoing explosion in the U.S. Special Forces command at the Defense Department, means that American foreign policy will have unprecedented ability to conduct covert operations worldwide, on the president's whim. Assassinate Iranian scientists? Go ahead. Support paramilitary rebels in the Ukraine? Sure. Secretly arm and deploy Syrian dissidents? Go for it.
That doesn't even begin to cover the domestic possibility for covert activities, given the effective merger between the CIA and the FBI begun by the Patriot Act and pushed hard by the 9/11 Commission.
