Formerly TOP SECRET records in Central Intelligence Agency’s archives, only declassified in 2013, outline the Office of Strategic Services plan to wage psychological warfare against Nazi Germany ahead of the D-Day invasion.

The Central Intelligence Agency’s “The World Situation in 1970” report was a strange mixture of realistic concerns, candid admissions, and forced optimism. In one of its more realistically optimistic moments, the CIA reported that the Soviets believed “rational Americans” would want a stable Europe. In response, President Richard Nixon asked if anything could be done to “cause more trouble” instead.

A copy of the US Navy’s 1975 guide to “Christening, Launching, and Commissioning” ships uncovered in the Central Intelligence Agency’s archives offers a fascinating history of the surprisingly rich tradition of ruining a perfectly good bottle of champagne.

The recently released Federal Bureau of Investigation file for former head of the American Civil Liberties Union Roger Baldwin document numerous times the groups came into conflict with each other. One notable incident, related to the Bureau’s wartime “Postal Censorship” program, led to a testy exchange between Baldwin and FBI Director J. Edgar Hoover after the Bureau investigated the writer and pioneering Libertarian Rose Wilder Lane over her comments on a postcard.

As part of MuckRock’s ongoing project to declassify and collect internal Central Intelligence Agency histories, the Agency recently released a copy of the history on coordination between inbetween intelligence agencies in the aftermath of World War II. The history outlines various “turf wars,” some which predate the Agency itself, which were the result of disagreements about what the law said and who had what responsibilities. According to the history, many of these disagreements and differing interpretations stemmed directly or indirectly from the language of the National Security Act of 1947, which both established and empowered the CIA, as being “purposefully vague.”
