The internet agrees with you: An estimated 20,000 slave laborers died manufacturing the Nazi V-1 flying bombs and V-2 rockets. More forced workers and concentration camp prisoners died building these weapons than the total number of civilians killed by them in combat strikes.
I am sorry, but you people are simpletons. Do you really think that the Nazis cared how many people died creating their “vengeance” weapons?
Every enemy death was a plus. Alcohol was mostly useless to any 20th century war effort. The metal in a V2 rocket was better used than in a tank that had no fuel.
Thanks!
