spying

Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence) from non-disclosed sources or divulging of the same without the permission of the holder of the information for a tangible benefit. A person who commits espionage is called an ''espionage agent'' or ''spy''. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law.

Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as industrial espionage.

One of the most effective ways to gather data and information about a targeted organization is by infiltrating its ranks. This is the job of the spy (espionage agent). Spies can then return information such as the size and strength of enemy forces. They can also find dissidents within the organization and influence them to provide further information or to defect. In times of crisis, spies steal technology and sabotage the enemy in various ways. Counterintelligence is the practice of thwarting enemy espionage and intelligence-gathering. Almost all nations have strict laws concerning espionage and the penalty for being caught is often severe. However, the benefits gained through espionage are often so great that most governments and many large corporations make use of it.

History

Espionage has been recognized as an importance in military affairs since ancient times.

The oldest known classified document was a report made by a spy disguised as a diplomatic envoy in the court of King Hammurabi, who died in around 1750 BC. The ancient Egyptians had a developed secret service, and espionage is mentioned in the ''Iliad'', the Bible, and the Amarna letters as well as its recordings in the story of the Old Testament, ''The Twelve Spies''. Espionage was also prevalent in the Greco-Roman world, when spies employed illiterate subjects in civil services.

The thesis that espionage and intelligence has a central role in war as well as peace was first advanced in ''The Art of War'' and in the ''Arthashastra''. In the Middle Ages European states excelled at what has later been termed counter-subversion when Catholic inquisitions were staged to annihilate heresy. Inquisitions were marked by centrally organised mass interrogations and detailed record keeping. During the Renaissance European states funded codebreakers to obtain intelligence through frequency analysis. Western espionage changed fundamentally during the Renaissance when Italian city-states installed resident ambassadors in capital cities to collect intelligence. Renaissance Venice became so obsessed with espionage that the Council of Ten, which was nominally responsible for security, did not even allow the doge to consult government archives freely. In 1481 the Council of Ten barred all Venetian government officials from making contact with ambassadors or foreigners. Those revealing official secrets could face the death penalty. Venice became obsessed with espionage because successful international trade demanded that the city-state could protect its trade secrets. Under Elizabeth I, Francis Walsingham was appointed foreign secretary and intelligence chief.

During the American Revolution, Nathan Hale and Benedict Arnold achieved their fame as spies, and there was considerable use of spies on both sides during the American Civil War. Though not a spy himself, George Washington was America's first spymaster, utilizing espionage tactics against the British.

In the 20th century, at the height of World War I, all great powers except the United States had elaborate civilian espionage systems and all national military establishments had intelligence units. In order to protect the country against foreign agents, the U.S. Congress passed the Espionage Act of 1917. Mata Hari, who obtained information for Germany by seducing French officials, was the most noted espionage agent of World War I. Prior to World War II, Germany and Imperial Japan established elaborate espionage nets. In 1942 the Office of Strategic Services was founded by Gen. William J. Donovan. However, the British system was the keystone of Allied intelligence. Numerous resistance groups such as the Austrian Maier-Messner Group, the French Resistance, the Witte Brigade, Milorg and the Polish Home Army worked against Nazi Germany and provided the Allied secret services with information that was very important for the war effort.

Since the end of World War II, the activity of espionage has enlarged, much of it growing out of the Cold War between the United States and the former USSR. The Russian Empire and its successor, the Soviet Union have had a long tradition of espionage ranging from the Okhrana to the KGB (Committee for State Security), which also acted as a secret police force. In the United States, the 1947 National Security Act created the Central Intelligence Agency (CIA) to coordinate intelligence and the National Security Agency for research into codes and electronic communication. In addition to these, the United States has 13 other intelligence gathering agencies; most of the U.S. expenditures for intelligence gathering are budgeted to various Defense Dept. agencies and their programs. Under the intelligence reorganization of 2004, the director of national intelligence is responsible for overseeing and coordinating the activities and budgets of the U.S. intelligence agencies.

In the Cold War, espionage cases included Alger Hiss and Whittaker Chambers and the Rosenberg Case. In 1952 the Communist Chinese captured two CIA agents, and in 1960 Francis Gary Powers, flying a U-2 reconnaissance mission over the Soviet Union for the CIA, was shot down and captured. During the Cold War, many Soviet intelligence officials defected to the West, including Gen. Walter Krivitsky, Victor Kravchenko, Vladimir Petrov, Peter Deriabin Pawel Monat, and Oleg Penkovsky, of the GRU (Soviet military intelligence). Among Western officials who defected to the Soviet Union are Guy Burgess and Donald D. Maclean of Great Britain in 1951, Otto John of West Germany in 1954, William H. Martin and Bernon F. Mitchell, U.S. cryptographers, in 1960, and Harold (Kim) Philby of Great Britain in 1962. U.S. acknowledgment of its U-2 flights and the exchange of Francis Gary Powers for Rudolf Abel in 1962 implied the legitimacy of some espionage as an arm of foreign policy.

China has a very cost-effective intelligence program that is especially effective in monitoring neighboring countries such as Mongolia, Russia, and India. Smaller countries can also mount effective and focused espionage efforts. For instance, the Vietnamese communists had consistently superior intelligence during the Vietnam War. Some Islamic countries, including Libya, Iran, and Syria, have highly developed operations as well. SAVAK, the secret police of the Pahlavi dynasty, was particularly feared by Iranian dissidents before the 1979 Iranian Revolution.

Today

Today, spy agencies target the illegal drug trade and terrorists as well as state actors. Between 2008 and 2011, the United States charged at least 57 defendants for attempting to spy for China.

Intelligence services value certain intelligence collection techniques over others. The former Soviet Union, for example, preferred human sources over
