I suspect this story will become part of WW2 folklore soon. No doubt backed by discoveries of elaborate plans and influential backers. It's purpose will be invented soon after.
With the amount of utterly preposterus and far fetched notions, regularly taken as concrete fact, about WW2, it is unlikely this silly idea will be the subject of much scrutiny.
Though the feasability of using female hormones to reduce agression, not to mention the problems of actually smuggling the stuff in, given some of the utter nonsense we've already been convinced is fact, about Hitler's domestic life, doesn't seem to be much of an issue.
Still, never mind the quality, feel the width.
