In the wake of the 2001 terrorist attacks, Washington pursued its elusive enemies across the landscapes of Asia and Africa, thanks in part to a massive expansion of its intelligence infrastructure, particularly of the emerging technologies for digital surveillance, agile drones, and biometric identification. In 2010, almost a decade into this secret war with its voracious appetite for information, the Washington Post reported that the national security state had swelled into a “fourth branch” of the federal government — with 854,000 vetted officials, 263 security organizations, and over 3,000 intelligence units, issuing 50,000 special reports every year.

Though stunning, these statistics only skimmed the visible surface of what had become history’s largest and most lethal clandestine apparatus. According to classified documents that Edward Snowden leaked in 2013, the nation’s 16 intelligence agencies alone had 107,035 employees and a combined “black budget” of $52.6 billion, the equivalent of 10% percent of the vast defense budget.

By sweeping the skies and probing the worldwide web’s undersea cables, the National Security Agency (NSA) could surgically penetrate the confidential communications of just about any leader on the planet, while simultaneously sweeping up billions of ordinary messages. For its classified missions, the CIA had access to the Pentagon’s Special Operations Command, with 69,000 elite troops(Rangers, SEALs, Air Commandos) and their agile arsenal. In addition to this formidable paramilitary capacity, the CIA operated 30 Predator and Reaper drones responsible for more than 3,000 deaths in Pakistan and Yemen.
