Of course like the Russians Solzhenitsyn wrote of in Lenningrad, the Jews at the time they were removed from their homes across Europe by the Nazis had little idea what was ahead of them, otherwise they would have violently resisted being taken from their homes. Even once crowded into ghettos, the Warsaw Jews IIRC were the only major group to figure out before it was too late that they had nothing to lose by resisting.
With the perfect clarity of hindsight, we scratch out heads at why these people; Russians and Jews couldn't see what lay ahead of them but such are the deceptive powers of a state in complete control of communications.
If the Jews in the Warsaw ghetto could amass enough weapons to fight back while locked up and surrounded by armed Nazis then how could anyone possibly expect to prevent people in a huge open country like this from acquiring whatever firearms we want badly enough?
True and imagine the German war resources that would have been tied down had every ghetto similarly revolted?
Someone wrote a book about this, "How do you kill six million Jews?"
Lie to them.
They went on to point out that lies from the entity with a monopoly on the use of force are always a serious matter.
