more like poison gas was a mad type of scenario, since it's not even that useful on the battlefield, and would instead be employed in strategic bombing, alongside other chemical and biological warfare, which would have more grave consequences for germany than the allies who import all their shit. in fact it's for the same reason britain didn't use chemical or biological weapons. didn't want the nazis to go all out with those against the isles in turn. rather if german engineering was so efficient why didn't they simply build a giant picrel that you can dump entire wagonloads into straight from the ramp? that wouldn't take long to 6million and you just gotta flush the sauce into the ocean. don't need to be a genius to come up with that either.
