that's what they all claimed after the war, that they would've been shot if they'd complained.

almost certainly a lie. at least, some wehrmacht soldiers complained that they did not enjoy having to massacre villagers on the eastern front and would rather not do it. they were not shot. they were not demoted.

some commanders on the eastern front complained that their soldiers are constantly drunk to deal with having to massacre villagers. they were not shot. they were not demoted.

also, nobody forced von braun to build rockets for nazis. he chose quite deliberately to serve the death machine. fuck him and his self-serving lies.
