Espionage

In the mid-1970s, as a result of disillusionment with the Vietnam War, the Watergate scandal, and the policies of détente, many Americans began to question the role of the CIA. Mass-media disclosures of intelligence agency abuses and failures were followed by investigations by presidential commissions and congressional committees, which resulted in new guidelines for secret operations and a new structure for executive and legislative supervision. Controversy over the CIA's role and control remains, however. One result is an ever-increasing amount of public information about intelligence services around the world. In Britain, MI5 remained unrecognized by statute until 1989, and MI6 until 1994.

Intelligence and espionage are terms most commonly associated with national foreign policies, yet secret information is needed to make decisions in politics, commerce, and industry. Political parties have always been interested in the strategic plans of their opponents or in any information that might discredit them.

Most large corporate enterprises today have divisions for strategic planning that require intelligence reports. Competitive enterprises are undeniably interested in the plans of their competitors; despite laws against such practices, industrial espionage is difficult to detect and control and is known to be an active tool for gaining such foreknowledge. Many of the tools of government intelligence work are used, including electronic surveillance and aerial photographic reconnaissance, and attempts are even made to recruit defectors.

All forms and techniques of intelligence are now aided by an accelerating technology of communications and a variety of computing and measuring devices. Miniaturized cameras and microfilm have made it easier for people engaged in all forms of espionage to photograph secret documents and conceal the films. Artificial satellites also have an espionage function—that of aerial photography for such purposes as detecting secret military installations. Information held or programmes running on computers are vulnerable to penetration by hackers, whether acting independently or for other bodies. The vanguard of these developments is highly secret, but it is known that telephones can be tapped without wires, rooms can be bugged (planted with electronic listening and recording devices) without entry, and photographs can be made in the dark. Of course this same technology is used in countermeasures, and the competition escalates between those seeking secret information and those trying to protect it.

In foreign embassies in sensitive areas, confidential discussions routinely take place in plastic bubbles encasing secure rooms, to protect the confidentiality of information. Intelligence agencies have long been known to be staffed with expert lip readers. Privacy of communications remains under constant assault by technological developments that offer threats to, but perhaps also promises for, human progress.
