Operation Paperclip
bringing evil into our home

Meanwhile, those who had been paying attention recognized the looming conflict between the west and the Soviet empire. Generals George Patton and Curtis LeMay were some of the most vocal, but they were not alone. There were others in the intelligence community and other places high in the US government that recognized the value of the technical expertise in the defeated land.
Both sides saw the value of these German scientists and engineers and grabbing the best was one of the first sources of contention in the cold war. In all, about 1,600 of the best and brightest Germany had produced found their way to US shores. It should be noted that when the Soviet Union acquired they same type of talent, they took them to Russia where they picked whatever knowledge they could from the men and then, sent them back to the rubble of a fallen Third Reich.
Most visible was rocket scientist Wernher von Braun, who led the US to the first lunar landing and a commanding lead in intercontinental ballistic missiles. There were some who raised the ethical concerns about bringing this member of the Nazi Party who created the V-2 rockets that terrorized Great Britain. They also objected to the fact that some of the labor to producer these rockets came from concentration camps.
Perhaps he was a victim of his place of birth and the necessity of being a member of the Nazi Party if he was to develop his craft. It may be a moot point since he is gone and so are the people who brought him into our country and gave him a good life while he kept us in the lead with our space program. It could be argued we received a net benefit from his help.
The same could be said for many other scientists who joined the victorious side. They helped advance the air craft industry and many others that ultimately produced more and better consumer goods.
There were others, recruited by the likes of Allen Dulles and Sidney Gottleib who had skills and knowledge these men sought greatly. They were looking for ways to get information from enemy captives and control their actions to make them unwilling or unknowing accomplices in their nefarious deeds. Some of the acquired technicians were well versed in these practices and, they too, were recruited.

These provided the roots of such programs as MKULTRA and other secret programs. Some of this was done in the country and ended in tragedies like Frank Olson's death. Others were taking place in black sites in Europe with POW and other “expendables”. It is ironic that the US helped defeat one of the most evil forces the world has seen then we brought some of the perpetrators into our own house and gave them a place to do their mad scientist thing.
Operation Paperclip: The Secret Intelligence Program that Brought Nazi Scientists to America
by Annie Jacobsen
In the chaos following World War II, the U.S. government faced many difficult decisions, including what to do with the Third Reich's scientific minds. These were the brains behind the Nazis' once-indomitable war machine. So began Operation Paperclip, a decades-long, covert project to bring Hitler's scientists and their families to the United States. Many of these men were accused of war crimes, and others had stood trial at Nuremberg; one was convicted of mass murder and slavery. They were also directly responsible for major advances in rocketry, medical treatments, and the U.S. space program. Was Operation Paperclip a moral outrage, or did it help America win the Cold War?
Drawing on exclusive interviews with dozens of Paperclip family members, colleagues, and interrogators, and with access to German archival documents (including previously unseen papers made available by direct descendants of the Third Reich's ranking members), files obtained through the Freedom of Information Act, and dossiers discovered in government archives and at Harvard University, Annie Jacobsen follows more than a dozen German scientists through their postwar lives and into a startling, complex, nefarious, and jealously guarded government secret of the twentieth century.
