I think you've read the wrong rules, Sir.

There's a note on strategic bombings in the rules too.
I know simulation of genocides, population exterminations, terror bombing etc. isn't allowed at least in mods (then again DH isn't a mod, but the rules probably apply to any game released or sponsored by PI). Terror bombing is kind of shady since in part the strategic bombing feature in-game is in part terror bombing.
Anyhow, I don't think nations lacking enough food to feed everyone, causing a percentage of people to die of malnutrition is not allowed to be simulated..?
