Exactly - you are your own last line.
Playing with words about the Warsaw ghetto is irrelevant to the core issue. The Jews weren't ready to defend themselves. Historical precedent suggests that easy genocides don't happen if the minority or target group can resist efficaciously. Can you lose the civil war - sure but that's a different game.
The claim that if a large percent of the 3.5 million Jews in Poland could reasonably defend themselves if they were prepared would not have impacted the Wehrmacht is stupid.
