After the last shots of World War II were fired and the process of rebuilding Germany and Europe began, the Western Allies and the Soviet Union each tried to obtain the services of the Third Reich's leading scientists, especially those involved in rocketry, missile technology, and aerospace research. Naturally, this was a delicate affair due to the fact many of the German scientists were not only active Nazis but had helped the Nazi war machine terrorize the world. At the same time, by the late war period, the Anglo-American Allies formed a clear picture of the Soviet state. Though forced to ally with the USSR's dictator, Josef Stalin, the West came to understand Communist Russia represented yet another hungry totalitarian power, and thus a very real threat to an independent Europe. British Prime Minister Winston Churchill realized the menacing character of the Soviets from the Katyn Forest Massacre of Polish army officers, if not before, while the Americans only gradually shed a naïve assumption of continued Russian friendliness after the war.

The result was the American-led "Operation Paperclip" on the Western side, which resulted in German scientists putting their expertise at the disposal of the U.S. and other NATO members. Operation Paperclip aimed not only to obtain the benefits of German scientific advances for the United States but also to deny them to the potentially hostile Soviets.

The Western approach, however self-interested, typically met with voluntary compliance on the German scientists' parts. In contrast, the Soviet answer to Paperclip, Operation Osoaviakhim, used the implied threat of imprisonment, torture, and death, the characteristic tools of Stalinist Russia, to coerce assistance from German scientists and engineers following the war. These men yielded rich dividends to the Soviet state in terms of achieving at least temporary technical parity with the USSR's western rivals.
