“Falsehood is a recognized and extremely useful weapon in warfare, and every country uses it quite deliberately to deceive its own people, to attract neutrals, and to mislead the enemy. The ignorant and innocent masses in each country are unaware at the time that they are being misled, and when it is all over only here and there are the falsehoods discovered and exposed. As it is all past history and the desired effect has been produced by the stories and statements, no one troubles to investigate the facts and establish the truth.”
