Many a man has been impressed by the ingenuity of secret agent operations, and intrigued by the subterfuge, gadgets, and disguises required to pull them off. Much of what we think about when we think about spies got its start as part of the Office of Strategic Services, the American intelligence agency during World War II.\n\nHere to unpack some of the history of the world of cloak and dagger operations is John Lisle, author of The Dirty Tricks Department: Stanley Lovell, the OSS, and the Masterminds of World War II Secret Warfare. Today on the show, Lisle explains why the OSS was created and the innovations its research and development section came up with to fight the Axis powers. We talk about the most successful weapons and devices this so-called \u201cDirty Tricks Department\u201d developed, as well as its more off-the-wall ideas, which included releasing bat bombs and radioactive foxes in Japan. We discuss the department\u2019s attempt to create a truth serum, its implementation of a disinformation campaign involving \u201cThe League of Lonely War Women,\u201d and its promotion of a no-holds-barred hand-to-hand combat fighting system. We also talk about the influence of the OSS on the establishment of the CIA and controversial projects like MKUltra.
