Why did the United States finally allow Qian Xuesen to return to China?

1June, 955, Qian Xuesen wrote a letter to Vice Chairman Chen Shutong on a piece of cigarette paper, which was sandwiched in a letter sent to relatives in Belgium, asking for help from the motherland. This letter was given to Premier Zhou. At the Sino-American ambassadorial talks in Geneva, China put forward the conditions for releasing 1 1 American pilot prisoners of war, and at the same time flashed Qian Xuesen's letter, demanding that the United States not obstruct Qian Xuesen's return to China. Under the negotiation of the China administration, the US immigration authorities finally agreed to release Qian Xuesen.

There is also a saying that Qian Lao mastered the secret technology at that time, but it was five years out of date when he returned to China. Because technology develops so fast, on the one hand, it is the cold war between the Soviet Union and the United States, on the other hand, it is also a great technological innovation promoted after World War II, so Americans are not worried that he will return to China with technology. They think that what Qian Xuesen knows is out of date. But the fact is that Qian Xuesen returned to China to develop missiles for China. 1964+00 China's first atomic bomb was successfully detonated in June, and China has its own nuclear weapons since then. Qian Lao played an important role in breaking the nuclear deterrent of the United States, and the people of China will never forget him.

I believe that when many people are in middle school, the history teacher will say something to you, that is, the amazing remarks of senior American generals: "Qian Xuesen is worth five divisions." This is the highest praise for a person, so why do senior American generals say this?

In the eyes of Americans at that time, Qian Xuesen was not a Chinese scientist who only engaged in scientific research in the United States. On the contrary, Qian Xuesen in the eyes of Americans is one of the founders of the American Rocket Power Laboratory, one of the founders of the National Aeronautics and Space Administration, and one of the leaders of the American "Yier Plan" to plunder talents and technology from defeated countries such as Germany in World War II. When Qian Xuesen participated in the "Yier Plan", he helped the United States systematically screen and select a large number of German scientists.

So from this perspective, everyone should understand that Qian Xuesen is not a scientist in a simple sense. He is a core scientific research leader who touches the core interests of the United States and a "strategic scientist". His most powerful knowledge weapon is not technology, but "the most advanced core technology thought". For these reasons, it was absolutely impossible for Americans to let him return to China at that time. So I found many excuses to keep Qian Xuesen.
