Oh, "Dave"/bn+ do stop repeating 'the Zionists declared war on Germany in 1933" like a demented parrot.
They didn't. You can tell by the undeniable fact that when Hitler declared war on Poland in 1939 he bombed the civilian population, encouraged looting, rape, and massacre, and occupied half the country. When no one declared war on Germany in 1933 none of this happened.
However, Hitler did begin his campaign against such German citizens who happened to be German with a boycott of Jewish businesses, and escalating antisemitic legislation aimed at making their life in Germany intolerable (just think about a government that orders some of its citizens to give up their old fur coats, and woolen clothes, or orders that Jewish men and women who are deaf or blind are not to be issued with identifying armbands that other Germans wear to help them negotiate traffic.)
Edward and Mrs Simpson were among the deluded people (who included Unity Mitford, Oswald Mosley and William Joyce) who had a sick admiration for Hitler, and possibly encouraged him to believe that the UK would not resist his plans for Central and Eastern Europe, which included the murder, and deportation of the ethnic population to make 'room' for the Germans.
