> My grandparents told me that people of German descent living in Pittsburgh suddenly began telling people they were really Hungarian. Such was the times. <
Ha! And I had Hungarian relatives in the US who told people they were Greek!
(They said that because Hungary was an ally of Germany in WW 2.)
Hungary went back and forth during the war, until the Germans basically engineered a coup in 1944. Up to that point, Jews in Hungary were safe, but by 1944, helped by the likes of Soros, they made up for lost time.
