Yes, I agree. To be clear, I chose my words carefully: * plausibly denied knowledge on the part of the Allied powers (i.e., their leaders) * denied knowledge on the part of the nearby Germans I agree with you that in truth, both parties likely knew. But today many/most believe that the Allied leaders did not know, and thus the denial is factually 'plausible'. But my point remains: Hitler did not announce the Holocaust to the world, but hid it. Which supports my point that if you wait for the evil-doers to step forward, don a red cape, and announce their evil plans and actions, you will be waiting forever and meanwhile they will manipulate you like a herd of sheep.
