the ALLIED HOLOCAUST : pure penicillin, for only some

The Nazis never fully carried out their original Hunger Plan and the Allies never carried out their original Penicillin plan.

So the Holocaust of Jews and Romas remains the outstanding horror of WWII, in terms of lives snuffed out prematurely and total suffering induced.

But it was a close run thing : because both the Nazi Hunger Plan and the planned shortage of pandemic-preventing Allied penicillin at war's end had the potential to kill far far more than 'The Holocaust' actually achieved.
