Operation FOOT was the expulsion of 105 Soviet officials from Great Britain carried out by Prime Minister of the United Kingdom Edward Heath in September 1971 as part of the Cold War. [1] It is "[t]he largest expulsion of intelligence officials by any government in history." [2] It "was a British response to the general Soviet plan to advance terrorist activities in the West." [3]
Though Britain had engaged in "tit-for-tat" expulsions previously, the expulsion of 105 diplomats was "unprecedented" and "sent shock waves through not just the Kremlin, but through the international community as a whole." [1]
The operation "marked the major turning point in Cold War counter-espionage operations in Britain" and "made Britain a hard espionage target for Soviet intelligence for the first time." [4]
Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence). A person who commits espionage is called an espionage agent or spy. Any individual or spy ring, 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.
Spy fiction is a genre of literature involving espionage as an important context or plot device. It emerged in the early twentieth century, inspired by rivalries and intrigues between the major powers, and the establishment of modern intelligence agencies. It was given new impetus by the development of fascism and communism in the lead-up to World War II, continued to develop during the Cold War, and received a fresh impetus from the emergence of rogue states, international criminal organizations, global terrorist networks, maritime piracy and technological sabotage and espionage as potent threats to Western societies. As a genre, spy fiction is thematically related to the novel of adventure, the thriller and the politico-military thriller.
Cold War espionage describes the intelligence gathering activities during the Cold War between the Western allies and the Eastern Bloc. Both relied on a wide variety of military and civilian agencies in this pursuit.
The Venona project was a United States counterintelligence program initiated during World War II by the United States Army's Signal Intelligence Service and later absorbed by the National Security Agency (NSA), that ran from February 1, 1943, until October 1, 1980. It was intended to decrypt messages transmitted by the intelligence agencies of the Soviet Union. Initiated when the Soviet Union was an ally of the US, the program continued during the Cold War, when the Soviet Union was considered an enemy.
John Cairncross was a British civil servant who became an intelligence officer and spy during the Second World War. As a Soviet double agent, he passed to the Soviet Union the raw Tunny decryptions that influenced the Battle of Kursk. He was alleged to be the fifth member of the Cambridge Five. He was also notable as a translator, literary scholar and writer of non-fiction.
Igor Sergeyevich Gouzenko was a cipher clerk for the Soviet embassy to Canada in Ottawa, Ontario, and a lieutenant of the Soviet Main Intelligence Directorate (GRU). He defected on September 5, 1945, three days after the end of World War II, with 109 documents on the USSR's espionage activities in the West. In response, Canada's Prime Minister, Mackenzie King, called a royal commission to investigate espionage in Canada.
Oleg Antonovich Gordievsky, CMG is a former colonel of the KGB who became KGB resident-designate (rezident) and bureau chief in London.
Operation Gold was a joint operation conducted by the American Central Intelligence Agency (CIA) and the British MI6 Secret Intelligence Service (SIS) in the 1950s to tap into landline communication of the Soviet Army headquarters in Berlin using a tunnel into the Soviet-occupied zone. This was a much more complex variation of the earlier Operation Silver project in Vienna.
Operation Ivy Bells was a joint United States Navy, Central Intelligence Agency (CIA), and National Security Agency (NSA) mission whose objective was to place wire taps on Soviet underwater communication lines during the Cold War.
As early as the 1920s, the Soviet Union, through its GRU, OGPU, NKVD, and KGB intelligence agencies, used Russian and foreign-born nationals, as well as Communists of American origin, to perform espionage activities in the United States, forming various spy rings. Particularly during the 1940s, some of these espionage networks had contact with various U.S. government agencies. These Soviet espionage networks illegally transmitted confidential information to Moscow, such as information on the development of the atomic bomb. Soviet spies also participated in propaganda and disinformation operations, known as active measures, and attempted to sabotage diplomatic relationships between the U.S. and its allies.
Atomic spies or atom spies were people in the United States, the United Kingdom, and Canada who are known to have illicitly given information about nuclear weapons production or design to the Soviet Union during World War II and the early Cold War. Exactly what was given, and whether everyone on the list gave it, are still matters of some scholarly dispute. In some cases, some of the arrested suspects or government witnesses had given strong testimonies or confessions which they recanted later or said were fabricated. Their work constitutes the most publicly well-known and well-documented case of nuclear espionage in the history of nuclear weapons. At the same time, numerous nuclear scientists wanted to share the information with the world scientific community, but this proposal was firmly quashed by the United States government.
Russia–United Kingdom relations, also Anglo-Russian relations, are the bilateral relations between Russia and the United Kingdom. Formal ties between the nations started in 1553. Russia and Britain became allies against Napoleon in the early-19th century. They were enemies in the Crimean War of the 1850s, and rivals in the Great Game for control of central Asia in the latter half of the 19th century. They allied again in World Wars I and II, although the Russian Revolution of 1917 strained relations. The two countries again became enemies during the Cold War (1947–1989). Russia's business tycoons developed strong ties with London financial institutions in the 1990s after the dissolution of the USSR in 1991. Due to the 2022 Russian invasion of Ukraine, relations became very tense after the United Kingdom imposed sanctions against Russia. It was subsequently added to Russia's list of "unfriendly countries".
Oleg Adolfovich Lyalin was a Soviet agent who defected from the KGB. His defection led to the expulsion of 105 Soviet officials suspected as being Soviet spies from Britain on 25 September 1971.
The United States of America has conducted espionage against the Soviet Union and its successor state, the Russian Federation.
The Committee for State Security, abbreviated as KGB was the main security agency of the Soviet Union from 1954 to 1991. It was the direct successor of preceding Soviet secret police agencies including the Cheka, OGPU, and NKVD. Attached to the Council of Ministers, it was the chief government agency of "union-republican jurisdiction", carrying out internal security, foreign intelligence, counter-intelligence and secret police functions. Similar agencies operated in each of the republics of the Soviet Union aside from the Russian SFSR, where the KGB was headquartered, with many associated ministries, state committees and state commissions.
The Consulate-General of Russia in San Francisco was a diplomatic mission in the 2790 Green Street building in Pacific Heights, San Francisco. It was operated by the Russian Ministry of Foreign Affairs. The building of the former consulate remains government property of Russia.
Russian espionage in the United States has occurred since at least the Cold War, and likely well before. According to the United States government, by 2007 it had reached Cold War levels.
Spying, as well as other intelligence assessment, has existed since ancient history. In the 1980s scholars characterized foreign intelligence as "the missing dimension" of historical scholarship." Since then a largely popular and scholarly literature has emerged. Special attention has been paid to World War II, as well as the Cold War era (1947–1989) that was a favorite for novelists and filmmakers.
The Secret Intelligence Service (SIS), commonly known as MI6, is the foreign intelligence service of the United Kingdom, tasked mainly with the covert overseas collection and analysis of human intelligence on foreign nationals in support of its Five Eyes partners. SIS is one of the British intelligence agencies and the Chief of the Secret Intelligence Service ("C") is directly accountable to the Foreign Secretary.
Operation Monopoly was a covert plan by the United States Federal Bureau of Investigation (FBI) to build a tunnel underneath the Soviet Embassy in Washington, D.C., to gather secret intelligence, in effect from 1977 until its public discovery in 2001.
