Stalin's Russia: political, cultural
and selling books; the more he revises the holocaust the more books
he sells and the more lecture invitations he gets.
To push a certain point of view: one of the deniers, Robert Faurisson,
seems to deny the Holocaust just to get into people's faces and to
generate controversy.
The need for enemies? to have someone to defeat, something to
overcome.
