What made them forgot ? maybe the comfortable life they live in israel and credit they spend , from the so called holocaust , Hitler killed 20 million russians , 1 million german homosexuals and 2 million gypsies , or Biharis like you say
, before europe was invaded by united states and hitler decided to kill jews too , why he did it probably because he was stupid ,
But nevertheless i don't get online to remind jews of the holocaust , i'm not your enemy .... you often will be very surprised at the kind of iranians who are actually your enemy...
