As part of Operation Paperclip, the OSS (which would soon become the CIA) quite notably did a lot of work to scrub prior existing reports classifying various Nazis as ‘ardent Nazis’… by basically just retyping said documents and altering a few words, adding ‘not’ in front of ‘an ardent Nazi’.

Thats what you call retroactive plausible deniability.

Von Braun was one of the people whose past was scrubbed in this way.

… He oversaw a goddamned series of underground slave mines and construction facilities where thousands were worked to death, to keep the Nazi rocket program going.

If he hadn’t been genius rocket man and had instead been building a super tank… he would have been hanged at Nuremberg.

PS: Another ‘fun’ fact: IBM built the computers that tabulated the accounting of the Holocaust, managed the databases that kept track of all the ‘undesirables’.

IBM shipped those computers over to Germany, and sent some of their employees over Germany to assist with technical support.

… The numbers tattooed on Holocaust Survivors?

Those are their UIDs in IBM’s system.

…

What, IMO, should have happened to all these Nazis and collaborators?

Bare minimum.
