Suspicion of espionage was their main option. Time proved them right. Nearly a dozen Soviet spies were convicted of passing information to the Soviets during this period about the atomic bomb in what was called the "Manhattan Project", the most famous spy being Emil Julius Klaus Fuchs. After this experience, the United States began to invest a large quantity of money in protecting their secret projects and fighting espionage.
