Show how this rule, if carried out, would have a tendency to make all nations devote too much work to the preparation of war supplies. Show the difference between the British blockade and the sinking of ships by German submarines. Would the blowing up of American factories by paid agents of the German government have been a good enough reason for the United States to have declared war? How did the voyages of the _Deutschland_ prove that the United States wanted to be fair to both sides in the war? What reasons had Austria and Germany for wishing peace in December 1916? Why did President Wilson ask the warring nations to state their aims in the war? How did Germany try to justify the sinking of ships without warning? Chapter XXII.
