When and where has there been a war since so-called public opinion has played a role in governmental calculations, in which each and every belligerent party did not, with a heavy heart, draw the sword from its sheath for the single and sole purpose of defending its fatherland and its own righteous cause from the shameful attacks of the enemy? This legend is as inextricably a part of the game of war as powder and lead. — Rosa Luxemburg, The Junius Pamphlet, 1915
