The Briskers prosper in Eretz Yisroel no thanks to a single zionist. They even refuse to accept a single shekel in government money that they are fully legally entitled to! They arrived there before the State ever existed and they will remain there long after the State ceases to exist.
Kastner is a mass murderer who has the blood of over half a million Jews on his bloody zionists hands. He deserves not an iota of thanks from anyone anymore than his friend and fellow nazi Adolff Eichmann, who Kastner helped in liquidating Hungarian Jewry to the gas chambers in Aushwitz. If anyone on the train, including the SR, owe any “thanks” to, it is to Adolf Eichmann who ordered the train and ensured its safe passage to Switzerland. Kaster ym’s was in no position to order a train or authorize its passage to leave nazi occupied territory. Eichmann ym’s had that ability and authorization and Eichmann is the one that ordered the train and authorized its departure. So “thank” Eichmann if you insist on thanking someone.
