German Jews were less than 1% of the German population in the 1930s, and maybe 2% if everyone with any Jewish ancestor was counted. Most of Germany’s Jews left the country by 1939.
Nazi Jew-killing had to be international; they were never just worried about Jewish influence in Germany.
Jews were still in Berlin, as late as 1943, they were some of the last to be deported to the Death Camps.
“Europe cannot find peace until the Jewish question has been solved. …One thing I should like to say on this day [the sixth anniversary of his being appointed Chancellor of the Reich] which may be memorable for others as well as for us Germans. In the course of my life I have very often been a prophet and have usually been ridiculed for it. … Today I will once more be a prophet: if the international Jewish financiers in and outside Europe should succeed in plunging the nations once more into a world war, then the result will not be the Bolshevization of the earth, and thus the victory of Jewry, but the annihilation of the Jewish race in Europe.”
-Adolf Hitler January 30, 1939
