Jews were not deported to Hungary during WWII. Hungary, allied with Germany, enacted anti-Jewish laws (1938–1941) but resisted deportation until German occupation (March 1944). Then, in 56 days, Eichmann and Hungarian gendarmerie deported ~437,000 Jews—mostly to Auschwitz.
Before 1944, Hungary was a relative refuge; ~800,000 Jews lived there (including refugees). After the Arrow Cross coup (Oct 1944), Budapest ghettoization and death marches followed. Raoul Wallenberg, Carl Lutz, and others saved tens of thousands with protective passes.
The premise inverts history: Hungary was a destination for Jews until it became a deportation platform.
