钱学森对这个问题的回答是：如果在美国和共产中国之间的战争是为了中国人民的利益，那么我将站在美国这边作战。

“我已说过我必然效忠中国人民，而如果在美国和共产中国之间的战争是为了中国人民的利益，我认为这是非常可能的，那么我将站在美国这边作战。对此是毫无疑问的。“
I have already said that my essential allegiance is to the people of China, and if the war between the United States and Communist China is for the good of the people of China, which I think is very likely to be, so then I will fight on the side of the United States. No question about that.
