Eleanor Roosevelt was instrumental in blocking the forced repatriation of large numbers of displaced persons to their various home countries that were in the USSR after WW2. A large number of these displaced persons were from the Ukraine(detailed numbers not known) and even though there was a huge effort by the USSR to get these people back, these largely failed and many countries settled them and gave them landed immigrant status. Exceptions were made for war criminals, who also tried to hide. Of those sent to the USSR, many were imprisoned/killed etc. Apologies for political stuff, but the spots on the leopard remain. (nothing against the beautiful leopards either)
