You are kidding me, right? Like, are you not at all aware?

Here's a good one for you... Thomas Watson, head of IBM sold HItler the computational equipment he couldn't have organized the Third Reich without. Then licensed them to build punchcard factories in Germany instead of buying it from the US to get around trade sanctions. He was awarded a metal for "Service to the Reich". Jews were a scapegoat during the Great Depression to blue collar workers. In 1939, Miami turned away the USS St Louis filled with German Jewish refugees and they were returned to Germany and put in concentration camps. Throughout the 30's, it was common for KKK and other hate groups to attack Jewish people and businesses, painting swastikas on their doors. Henry Ford was a well-known antisemite who praised Hitler's "Mein Kampf" and would not hire jews. Even during WWII, the US maintained Jewish immigration restrictions which were designed to prevent what they felt were 'undesirables' from flooding US cities.
