mezonos maven- what you are writing is preposterous and stands the truth on its head. There were PLENTY of reports about camps and killing fields. Polish refugess went through Hungary by the hundreds, maybe thousands. Prominent rebbes (belz, Bobov) came from the ghettos and passed through Hungary in 1944. Everyone knew that they were killing jews and many heard of the camps. A nice drawing oh Auschwitz would not have made an iota of difference.
Two things happened; the jews of hungary, by and large, just could not believe in the horror and two- there was precious few places to flee.
It is preposterous to say that,had they seen the Vrba report, they suddenly would have left their towns en masse or they would have grabbed guns and resisted. This is a stupid argument. (I also point out that the only few jews tht resisted ith arsm were the secular ones)it is made of total fabrication.
You have fallen prey to the post-war chareidi(mainly satmar) myth that the Zionists were all-powerful and that everything was their fault. Kasztner became the convenient poster boy for this historical invention.
The truth is totally different, because every person made mistakes and the real culprits are the damned NAZIS-JEMACH SHEMOM.
