This article in The Daily Beast has some terrifying quotes from Curtis LeMay, who massacred hundreds of thousands (millions?) of Japanese civilians in World War II and almost started World War III in 1969.

• “There are no innocent civilians. It is their government and you are fighting a people, you are not trying to fight an armed force anymore. So it doesn’t bother me so much to be killing the so-called innocent bystanders.”
• “When the Russians had acquired (through connivance and treachery of Westerns with warped minds) the atomic bomb and yet didn’t have any stockpile—that was when we might have destroyed Russia completely and not even skinned our elbows doing it.”
• “My solution would be to tell the North Vietnamese that they’ve got to draw in their horns and stop their aggression or we’re going to bomb them into the Stone Age.”
