Their object is twofold: first, to convince leaders of public opinion that the only sure way to prevent war is for the nations of the world to unite to remove the causes of war; and, second, that violent hostilities having broken out ... the minds of men must now be turned to such post-war settlement of those differences which have brought about hostilities as will pave the way to an orderly and peaceful world"--Introd.
