Preface: In response to legislation passed in 1985, the Department of State on July 30, 1986, submitted to Congress a document titled Active Measures: A Report on the Substance and Process of Anti-U.S. Disinformation and Propaganda Campaigns. This report updates that document, focusing on events and changes which occurred between June 1986 and June 1987. Both reports were prepared by the Active Measures Working Group.

One fall day in 2006, Alexander Litvinenko, a Russian defector who once worked in Moscow’s secret intelligence community and who became a prominent Kremlin critic in the United Kingdom, ate sushi for lunch before meeting with two former colleagues from his spy agency days at the Pine Bar in London’s Millennium Hotel. The anti-corruption crusader was reportedly set to travel to Spain to investigate the Russian mob there. But just a few short weeks later, Litvinenko was dead.

The series "Arms Control in Today’s (Dis)information Environment," produced by scholars from the Institute for National Strategic Studies, National Defense University, encompasses a trio of papers that delve into the intricate relationship between disinformation and arms control. This scholarly work aims to foster a comprehensive dialogue on the potential influence of disinformation on the formulation and implementation of future arms control treaties and agreements.
