The present German submarine warfare against commerce is a warfare against all mankind.... Our motive will not be revenge or the victorious assertion of the physical might of the nation, but only the vindication of right, of human right, of which we are only a single champion.. Armed neutrality, it now appears, is impracticable.

It would be the resumption of unrestricted submarine warfare that would ultimately bring the United States into the war.

14. Militarism
That which has driven the masses of Europe into the trenches and to the battlefields is not their inner longing for war; it must be traced to the cutthroat competition for military equipment, for more efficient armies, for larger warships, for more powerful cannon. You cannot build up a standing army and then throw it back into a box like tin soldiers.
-Emma Goldman, from "Preparedness: The Road to Universal Slaughter"
