Shmuel Tamir, Gruenwald's attorney, claimed that this was one of the main reasons he felt that Kasztner had been nothing more than a German collaborator, to save his family and perhaps for money. In Kasztner's defense, Eli Reichenthal says that at the point when the three paratroopers reached Budapest, what motivated Kasztner's decisions were the risk to the deal (which Kasztner believed was real and therefore could save many more Jews) and Eichmann's blackmail (having Kasztner's family together with the Hungarian Zionist leadership on the train). This was something Kasztner could not reveal at the trial; "I had reasons" was his answer to Szenes's mother.
