Known as "the Great War," the world's first truly global conflict is remarkable in what might now be termed modern espionage. World War I was witness to plenty of "firsts." Apart from the contribution made by aerial reconnaissance and the interception of wireless telegraphy, telephone and cable traffic, there was the scientific aspect, with new machines of war, such as the submarine, sea-mine, torpedo, airship, barbed wire, armored tank and mechanized cavalry in a military environment that included mustard gas, static trench warfare, the indiscriminate bombardment of civilian population...

Although China's intelligence activities may not have been well documented, they can be traced back to the ancient writings of Sun Tzu, and espionage has been a characteristic of Chinese domestic politics and international relations ever since. The People's Republic of China has long engaged in espionage, but relatively little is known about Chinese techniques, methodology, personnel, and organizations in comparison with what the West has learned about other more conventional intelligence agencies that conduct operations across the world. Whereas most intelligence services have suffered...

Signals Intelligence (SIGINT) encompasses the various disciplines of wireless interception, cryptanalysis, communications intelligence, electronic intelligence, direction-finding, and traffic analysis. It has become the basis upon which all combat operations are undertaken. It is now widely recognized as an absolutely vital dimension to modern warfare and it has proved to be a vital component in the counter-intelligence war fought between the West and Soviet bloc intelligence agencies. The Historical Dictionary of Signals Intelligence covers the history of SIGINT through a chronology, an...

This text details MI5's interception and exploitation of secret Comintern wireless traffic, which revealed the first evidence of widescale Soviet espionage in Britain.

Intelligence is now acknowledged as the hidden dimension to international diplomacy and national security.

This second edition of Historical Dictionary of International Intelligence covers its history through a chronology, an introductory essay, and an extensive bibliography. The dictionary section has over 500...

With the recent declassification of secret documents new light has been shed on old mysteries. For example, we now know that what might be termed the "JFK assassination conspiracy industry" was deliberately fueled and manipulated by the KGB so as to distract the CIA and undermine confidence in successive U.S. administrations. Also, new evidence continues to emerge of Vladimir Putin's commitment to the extra-judicial elimination of "extremists" overseas, as legitimized by the Duma in July 2006. Controversially, the legislation included a definition of "extremists" as "those slandering the...
