Tzohar head Rabbi David Stav blasted a recent letter written by Holocaust survivors contending that Israel's treatment of Sudanese and Eritrean migrants was akin to what they suffered at the hands of the Nazis. "I think there is a great deal of respect for Holocaust survivors for their steadfastness and heroism, but it is inconceivable that there will be someone who compares the murder of children, women and men, in crematoria and gas chambers, to Israel's refugee problem" said Stav.
