Maybe this is history repeating itself: the story of the father of Chinese space program [1] was quite pertinent:
> During WWII, he was involved in the Manhattan Project, which ultimately led to the successful development of the first atomic bomb in America.
> During the Second Red Scare, in the 1950s, the US federal government accused him of communist sympathies. In 1950, despite protests by his colleagues, he was stripped of his security clearance. He decided to return to China...
> Upon his return, he helped lead the Chinese nuclear weapons program. This effort ultimately led to China's first successful atomic bomb test and hydrogen bomb test, making China the fifth nuclear weapons state, and achieving the fastest fission-to-fusion development in history.
> Qian was invited to visit the US ..., but he refused the invitation, having wanted a formal apology for his detention. In a reminiscence published in 2002, Marble stated that he believed Qian had "lost faith in the American government" but that he had "always had very warm feelings for the American people."
