The Man Who Ended War [EPUB ebook] 

The Secretary of War of the United States receives a letter sent to his and all other nations, declaring that war has too long devastated the earth and the time has come for peace. It orders them to destroy their weapons of warfare and disband their militaries. The letter ends: ’One year from this date will I allow for disarmament and no more. At the end of that time, if no heed has been paid to my injunction, I will destroy, in rapid succession, every battleship in the world. By the happenings of the next two months you shall know that my words are the words of truth.’ It is signed ’The man who will stop all war.’
