Christopher Andrew & David Barrett

For the duration of the Cold War, the CIA and the KGB were tireless adversaries. Through the exhaustive research efforts of two men -- a historian, and a political scientist -- we now know much more about how each agency operated. Today we'll meet those men. David Barrett is associate professor of political science at Villanova University, and author of The CIA And Congress: The Untold Story from Truman to Kennedy. Christopher Andrew is author of The World Was Going Our Way.
