How WW2's Greatest Secret Got Exposed

In WW2, the United States launched the Manhattan Project, a top-secret $26 billion operation to build the first atomic bomb before Nazi Germany. Led by General Leslie Groves and J. Robert Oppenheimer, the project built hidden cities and employed 600,000 people under the strictest security in history. But despite their incredible efforts, the ultimate weapon was not safe from espionage.
