I am Czech born. Slovakia was German ally and was independent during WWII from what happened in the Czech lands. Slovakia had own guards Hlinka which was fascist military organization that killed thousands of people in the countryside. Slovakia itself was not occupied by Germany until August 30, 1944 when the government attempted to switch side once Red Army arrived. In occupied Czech territory, there was no Czech SS due personal order from Adolf Hitler. Of course there were Nazi sympathizers and wanted to create their own Saint Wenceslas unit, but they were kicked from Berlin because Hitler insisted that no Czech will ever wear SS uniform. At the end of the WWII he changed mind, but by then, they were not enough people interested to join. These who wanted to be in SS generally joined Slovak or Ukrainian units.
The guy I studied was hard core Nazi as was his entire family. It was weird to sit at family table with bible and WT publication while his grandpa was in armchair with picture of him in his youth in Nazi uniform. I had about four bible visits, but I got spooked out, because the guy I studied with (he was very interested in WT and liked the prospect of mass genocide in Armageddon) was too dangerous. It was just really weird experience, and I really liked Jews; and they were dreaming that they will get rid of them once for good (with the rest of the undesirables). My father served in military and was stationed in Slovakia in the 1950's and 60's, and he told me that some of his senior staff there were former Fascists and one was ex Arrow from Hungarian speaking part of Slovakia (part that was ceded during WWII to Hungary). All of them became a good communists in the 50's under Stalin, but a few were exemplary executed in 1958 once their Nazi past came out at the time my father was stationed there.
What hit me at that time with that family was how close were JW mentally in antisemitism with them. In my hometown there was once thriving Jewish community. Once I was with sister doing field service and we walked by former Jewish ghetto. This sister points to the cemetery and she said not of these MF will get resurrected because they are Jesus-killer and were eternally condemned to death. That moment I wanted to slap her, because in my life, I met many great Jews and I eventually married one.
