That is a bit back to front to what I was saying - G_d gave us all, including Hitler et al, the ability to choose him, or not. It was that Hitler et al, decided not to follow his Law or to accept that he even exists as the Creator of the world, which led them to do what they did to his chosen people (and others), as they did to his Son.
I do not think it was because those Jews did not necessarily believe in Yeshua - they suffered in the same way that Yeshua suffered: undeserved, unwarranted, false in application and outcome etc etc. Neither Yeshua, nor the victims of hashoah, were being punished, directly, for their belief or un-belief by G_d; the whole of mankind were tempted by hasatan to rid the earth of Jews, as a people - many did it gladly, many did it because they don't believe in G_d and some did it because it was, to them, an 'Act of G_d' because they didn't believe in Yeshua. If those who believed in G_d had stood up for them, the outcome might have been very different, but even after the war the 'Exodus' vessel was still being refused a place to off-load those who had been saved.
