This determination to create a 'superior race' is, as you may remember, the same drive that fueled Hitler's regime in Germany. One needs only to read Linda Hunt's book, Secret Agenda: The United States Government, Nazi Scientists, and Project Paperclip, and then visit the Holocaust Museum in Washington, DC, in order to put two and two together.
If you observe some of the pictures of innocent people in the concentration camps as they are being used for brain and behavior experimentation, it's easy to ascertain that more was occurring than just the torture of innocent Jewish people for religious or racial purposes.
This experimentation was also done intentionally in order to further the understanding of the mind and body, and how people could be controlled.
We as a people have not fully embraced the reality of the horrors in Germany that were perpetrated on victims there, and to that end we allow it to continue to the present, as those who should have been prosecuted for their war crimes often went free.
As a matter of fact, through Project Paperclip, many were brought to our country by the Office of Strategic Services (OSS), which was our own intelligence apparatus at the time.
They were placed in our major universities and hospitals to continue their unconscionable scientific research. It was through the invaluable wizardry of one of these Project Paperclip Nazis, General Reinhard Gehlen (German Intelligence Specialist), that our fledgling CIA came into being just after World War Il, and the "Cold War" was born.
