Whether they were considering giving Hitler estrogen to get rid of his iconic mustache, or merely to temper his aggressive behavior, historians have discovered a plan by the British Intelligence to administer estrogen to Hitler.
Perhaps it was decided that Hitler was unstable enough without messing with his hormones, but, in any case, the plan was not put into action. Interestingly enough, the British Intelligence did have the means and people in place capable of dosing Hitler’s food.
One might think it might be more useful to poison Hitler, but the British Intelligence had an answer for that too: Hitler’s food was tested for poison, but estrogen, which is flavorless, would go unnoticed. Throughout history, intelligence agencies have employed or considered employing new science in secretive ways to affect politics. At one point, the CIA had a plan to poison Fidel Castro so that his beard would fall out.
