At the end of World War 2 the US ran all over Germany snapping up German scientists, most of whom would be tried for crimes against humanity but their expertise was needed so Operation paperclip protected these criminals and moved most of them to the US under the protection of the government.
More about Operation paperclip here…..
Operation Paperclip, named after the use of the ordinary paperclip attached to the personnel files of select German scientists, was a special operation of breathtaking scope. Instead of highly trained teams tasked for important combat missions, these teams were hunters and gatherers sifting and searching through the wreckage and ruin of a devastated Germany. Theirs was a high-stakes contest against an equally determined Russia and other less malevolent former allies. German scientists and technologies were the pawns, and the prize was nothing less than national security and preeminence as a world power. When it was concluded, hundreds of German scientists and their families, tons of documents, hardware, weapon systems, and technologies would be transferred from Germany to the United States.
Officially, Operation Paperclip concluded on Sept. 30, 1947. In a public statement, the Army announced that the operation had brought into the United States 457 scientists and 453 dependents. But a closed-door decision was made to allow Operation Paperclip to continue, this time as a top secret program. To justify the continuation, the Air Force stated that the 209 German scientists working for it had substantially advanced the development of weapons systems and the scientists were “superlative specialists … the best available in the world today.” They were saving the Air Force millions of dollars and an estimated 10 years in cost and development. The Navy added its praise, stating that German mathematicians, aerodynamicists, and experts in heat transfer had proven that “their professional education and training [were]superior to that of any U.S. personnel available.”
Some of the research that America used in their space program was testing done on Jewish prisoners that resulted in a horrific death and yet we decided that it was somehow okay to use this research if it put us a head of the Russians.
I personally have a problem with this type of program….a war criminal is a war criminal and should face the same judgements that others had to face.
