Hitler was fully responsible for the order for the mass
executions in Poland in 1939 and 1940. He was also actively
engaged in setting up plans for a Jewish reservation in Poland
and he backed the Madagascar plan. He was continually
preoccupied with further deportations and deportation plans.
In 1941 Hitler ordered the extermination of the "Jewish-Bolshevist intelligentsia" and the elimination of every potential enemy in the occupied Eastern territories. He was fully aware of mass executions of Jewish civilians in the occupied Eastern territories.
