The really weird thing is that the Bolivian Jews (who mostly came from Germany in the 1920s and 1930s) had really close business contacts with the "other Germans" who started arriving in the late 1940s...
I lived close to a lot of Germans in Paraguay when I was a kid. A lot of them had fled Germany due to forced military service. They were pacifists. I have always suspected that after the was there were a few nazis living among them.
Are you from Bolivia originally? It is weird that your mother tutored an ex-Nazis. That's bizarre! I have read that Bolivia has a small Jewish population. I have heard in Bolivia, German is practically the second language there. There are supposed to be many German colonies there. I know Argentina and Paraguay have plenty of them, which partially explains why many Nazis fled to South America, mainly Argentina. Also, Juan and Evita Peron helped them escape to Argentina because they sympathized with Nazis and wanted their money, which are in Swiss banks. I also know many Nazis fled to the Middle East, mainly Egypt and Syria and later Iran, Saudi Arabia, and Iraq.
