In May 1940, during the invasion of France, Himmler had written a paper for Hitler entitled ‘Some Thoughts on the Treatment of Alien Populations in the East’. He suggested screening the Polish population so that the ‘racially valuable’ could be Germanized, while the rest were turned into slave labour. As for the Jews, he wrote: ‘I hope completely to erase the concept of Jews through the possibility of a great emigration to a colony in Africa or elsewhere.’ At that stage, Himmler considered genocide – ‘the Bolshevik method of physical extermination’ – to be ‘un-German and impossible’.
