[I wonder how many of people who were deprived of citizenship actually survived?]
https://en.wikipedia.org/wiki/The_Holocaust
Non-German Jews were caught flat-footed by Germany’s quest to conquer the entire continent.
But most of them "voluntarily" gave up their citizenship. I am guess many who were deprived of their citizenship were not allowed to leave.
Jews were sleepwalking from 1800-1945 thinking the majority of Christian Europe would FINALLY accept them as fellow Germans (or citizens of all other European nations) as part of the “Emancipation”.
Jew-hatred was rampant for 2000 years but in the 18th, 19th and early 20th centuries was also very strong.
Hitler’s base for annihilation was already set in place before 1933.
Ze’ev Jabotinsky (amongst others) as late as the late 1930’s of the coming Holocaust. Many stayed in place thinking there would be a sort of WWI Chivalric civility in terms of how POWs were treated or those under foreign occupation.
They missed all the clues, all the signs, all the violence, all the opportunities to run away but who could believe what was about to happen?
