Calvin Coolidge Quote

But while we put our trust not on force but on a reign of law and the administration of justice, yet we know that the maintenance of peace can not but to a large extent be dependent upon our sentiments and desires,. In spite of all the treaties we may make and all the tribunals we may establish, unless we maintain a public opinion devoted to peace we can not escape the ravages of war. A determination to do right will be more effective than all our treaties and courts, all our armies and fleets. A peaceful people will have peace, but a warlike people can not escape war.
