I see the nations of the world arming in ways that have never before been known in the modern world. I am not speaking of new forms of poison gas, heavier or swifter bombing planes, or parachutes to land brigades of soldiers... What is revolutionary is that the minds of men, women and children are being deliberately trained, directed, distorted, by every conceivable instrument of education and propaganda, to make them tolerant of war, receptive of war, prepared for war, lovers of war. The greatest menace in the world today is not poison gas. There are gas masks against that. The menace is poisoned words, poisoned ideas.
