I started thinking about this after reading about Nazi's and former SS that are still be prrosecuted to this day, even when they are in their 90s. Surely the companies that built Hitler's tanks and planes contibuted greatly to allied casualties too.
More of course can be said here, but there are some great previous answers related to this such as this thread with discussion both from /u/henry_fords_ghost and /u/kieslowskifan, focusing on the post-war success of Volkswagen.
As a follow-up, what has come out of American companies that helped execute the holocaust, like IBM and J.P. Morgan? Have any of them ever owned up to what they did?
