Most of that is speculative BS (by a guy writing a book, John Loftus), in fact the article itself says
The most tantalising part of the story remains shrouded in mystery: the connection, if any, between Prescott Bush, Thyssen, Consolidated Silesian Steel Company (CSSC) and Auschwitz
Prescott Bush was a liberal for the most part. His involvement with UBC was commercial, he was not a Nazi sympathizer. He voted to Censure McCarthy in 1954. He was also involved in Planned Parenthood, and was a supporter of the United Negro College Fund, including being chairman at one point. Nazi’s were totally against such things.
Again, that article is speculation by a guy writing a book. Oh, one part that is not speculation from 1924:
One of the first jobs Walker gave Bush was to manage UBC. Bush was a founding member of the bank and the incorporation documents, which list him as one of seven directors, show he owned one share in UBC worth $125. Yes there were 7 directors and 4,000 shares. Bush was one of the 7, and had 1 share only.
Joe Conanson, an excellent and respected liberal writer, says the Bush-Nazi stuff is rubbish, as do many historians.
Yes, like MANY US businesses, they did work with German companies in the 1930’s. That does not make them Nazi sympathizer, that’s “Glen Beck” type linking. In fact, also from your article:
There is no dispute over the fact that the US government seized a string of assets controlled by BBH - including UBC and SAC - in the autumn of 1942 under the Trading with the Enemy act. What is in dispute is if Harriman, Walker and Bush did more than own these companies on paper.
Erwin May, a treasury attache and officer for the department of investigation in the APC, was assigned to look into UBC’s business. The first fact to emerge was that Roland Harriman, Prescott Bush and the other directors didn’t actually own their shares in UBC but merely held them on behalf of Bank voor Handel. Strangely, no one seemed to know who owned the Rotterdam-based bank, including UBC’s president.
