National intelligence systems
It is likely that during the Cold War some national intelligence systems, especially those in the major countries, grew beyond their optimal size. Some countries also have experienced problems controlling their intelligence systems. In both democracies and authoritarian societies, these organizations are in a position to demand that their operations and the information they collect be kept secret, not only from the public but also from most government officials. The need for secrecy obviously makes adequate oversight difficult to achieve. Moreover, secret services historically have been used as vehicles of political conspiracy and intrigue. In part because of rapidly advancing technology, intelligence systems are likely to grow in power and autonomy in the 21st century. In order to avoid becoming their virtual prisoners, legislative and executive bodies must be cognizant of the need for effective policy controls.
The intelligence systems of three countries—the United States, the Soviet Union, and the United Kingdom—have been used as general models for the organization of most other intelligence services. The American system was adopted by many of the countries that came under U.S. influence after World War II; that of the Soviet Union was instituted in most communist countries; and that of the United Kingdom was used by most countries with parliamentary governments.
The United States
The decision to establish the CIA reflected the United States’s experience during World War II with the OSS and a postwar desire to create a central organization for defense. This organization was to include a partially unified Department of Defense and a National Security Council (NSC), chaired by the president. The CIA is under the jurisdiction of the NSC.
At the close of the war there was intense debate about how much centralization was needed. Some wanted a single overarching intelligence system that would eliminate the separate units operated by the army, navy, and the State Department. Others wanted to turn over to the State Department all but technical military intelligence functions. The outcome was a compromise that created the CIA but allowed other departments and agencies to retain their own intelligence sections. Since then the idea of a single intelligence system has given way to the concept of an “intelligence community” comprising the CIA, the Defense Intelligence Agency (DIA), separate army, navy, and air force intelligence staffs, State Department intelligence, the National Security Agency (NSA), a Department of Energy nuclear intelligence unit, and the Federal Bureau of Investigation (FBI). The National Security Act (1947), which has remained the basic charter for the organization of American intelligence, assigned the CIA five specific functions: (1) advising the NSC on intelligence matters related to national security, (2) recommending to the NSC measures for the efficient coordination of the intelligence activities of departments and agencies of government, (3) collecting and evaluating foreign intelligence and making certain that it is properly communicated within the government, (4) carrying out additional services for other intelligence agencies that the NSC determines can best be performed centrally, and (5) carrying out other functions and duties related to national security intelligence as the NSC may direct. The CIA also conducts secret political and economic intervention, psychological warfare, and paramilitary operations in other countries, functions that were treated as a Cold War necessity on the basis of a somewhat loose interpretation of the original charter. Following the September 11 attacks in 2001 and the passage of the Homeland Security Act in the following year, CIA analysts were integrated into the intelligence sections of the new Department of Homeland Security. CIA officers also were assigned to work in FBI units, and FBI agents began to work at CIA headquarters. The post of director of national intelligence subsequently was established to coordinate the activities of the various intelligence agencies. The director also served as the president’s chief adviser on intelligence.
At the beginning of the 21st century the CIA was thought to employ 15,000 to 20,000 people full-time in the United States, mainly in Washington, D.C., and several thousand more overseas. Policy and operational guidelines for the CIA are contained in periodically revised presidential executive orders and numerous secret National Security Council Intelligence Directives, which define the CIA’s functions and establish jurisdictions in areas in which other intelligence agencies might have a claim.
The CIA comprises four major directorates responsible for intelligence, operations, administration, and science and technology. It is managed by a director and a deputy director, both appointed by the president and subject to Senate confirmation. The director of central intelligence (DCI) plays two distinct roles as both head of the CIA and a leading adviser to the president on intelligence matters relating to national security. The powers vested in the office of the DCI have increased over the years.
The CIA produces independent intelligence information, including bulletins and daily briefings for the president. Since the end of the Cold War it has become increasingly concerned with the activities of nonstate actors as well as with economic intelligence and industrial espionage. It also has provided greater direct support to U.S. military operations. Following the Persian Gulf War (1990–91), the CIA was asked to rapidly enhance its ability to provide direct tactical support to military commanders on the battlefield, and in the following decade it did so in both the Balkans and Afghanistan.
The principal role of the FBI is domestic counterintelligence. The FBI director serves under the attorney general in the Department of Justice. An assistant director of the FBI heads the National Security Division, whose budget, personnel, and organization are secret. The FBI and CIA cooperate in counterintelligence and counterterrorism and in efforts to combat international crime. The DIA and agencies of the armed services also perform counterintelligence functions within their limited jurisdictions.
The NSA is the largest, most expensive, and perhaps least known of all U.S. intelligence organizations. Its basic function is signals intelligence—the making and breaking of codes and ciphers. Created by presidential directive in 1952, the NSA has remained, despite its enormous size and worldwide activities, the most secret of the acknowledged U.S. intelligence units; even the directive creating the agency remains secret. Headed by a high-ranking military officer, the NSA is under the jurisdiction of the secretary of defense but maintains a modest degree of autonomy. From its headquarters near Washington, D.C., the NSA conducts an immense variety of electronic espionage activities, many of which make use of sophisticated listening devices placed on planes and ships and in ground installations overseas. The NSA’s “Echelon” computer program, which is maintained with the assistance of the intelligence agencies of Britain, Canada, Australia, and New Zealand, is built on a global network of computers and automatically searches through intercepted e-mail, fax, and telephone messages for preselected keywords. The system automatically searches each word of all messages in the frequencies, channels, or addresses selected. The program was designed to produce counterterrorism and counterintelligence information and to allow the countries running it to address the problems of global crime more effectively. It has, however, raised significant concerns about civil liberties, since it allows intelligence agencies to open any personal message or business communication. It is estimated that the NSA employs 20,000 people, but its activities also involve thousands of additional personnel from the armed services.
The DIA, established in 1961, is the major producer and manager of intelligence for the Department of Defense and is the principal adviser on military intelligence matters for the secretary of defense and the chairman of the Joint Chiefs of Staff. It supplies military intelligence for national reports and estimates, coordinates Department of Defense collection requirements (classified information requested by military commanders for planning and operational purposes), and manages the military attaché system. Although the agency is staffed by personnel from each of the armed services, more than half of all DIA employees are civilians.
Through its Bureau of Intelligence and Research, the Department of State collects, analyzes, and disseminates large quantities of political, economic, and cultural information about countries in which the United States has accredited representation. The bureau, known in the intelligence community by the acronym INR, has the dual function of meeting the requirements of the intelligence community as set by the NSC and the State Department’s own intelligence needs. Area specialists constitute the bulk of the INR’s comparatively small staff.
The Department of Energy is represented within the intelligence community by an assistant secretary for defense programs, whose responsibilities include nuclear intelligence. The department’s Office of Intelligence is responsible for providing intelligence support to policy makers, collecting and evaluating intelligence on nuclear nonproliferation, and producing and disseminating energy assessments; such reports include information on a country’s nuclear arsenals and its potential for producing nuclear weapons.
Although the creation of the DIA sharply reduced the role of the separate armed forces intelligence services, each of them continues to perform significant tactical and technical intelligence and counterintelligence activities. Army intelligence is headed by the deputy chief of staff for intelligence. The Office of Naval Intelligence (ONI), headed by the director of naval intelligence, is responsible for foreign intelligence and cryptology. Air Force intelligence is headed by the director of intelligence, surveillance, and reconnaissance, who manages both technical and human intelligence programs. The National Air Intelligence Center produces tactical intelligence for targeting and mission planning.
The Department of Defense also controls the National Reconnaissance Office (NRO), one of several highly secret units that design, build, and operate satellites. Although it was created in the early 1960s, the NRO’s existence was declassified only in 1992. Its size and importance have grown with advances in surveillance technology. Its programs are perhaps the most expensive—and useful—sources of intelligence available to the U.S. government. The National Imagery and Mapping Agency (NIMA) was created in 1996 under the aegis of the Department of Defense to produce imagery intelligence for the U.S. military and other government agencies.
