This minimum of right the German Government has swept aside, under the plea of retaliation and necessity and because it had no weapons which it could use at sea except these, which it is impossible to employ, as it is employing them, without throwing to the wind all scruples of humanity or of respect for the understandings that were supposed to underlie the intercourse of the world. [Sidenote: Lives cannot be paid for.] I am not now thinking of the loss of property involved, immense and serious as that is, but only of the wanton and wholesale destruction of the lives of noncombatants, men, women, and children, engaged in pursuits which have always, even in the darkest periods of modern history, been deemed innocent and legitimate. Property can be paid for; the lives of peaceful and innocent people cannot be. The present German submarine warfare against commerce is a warfare against mankind. [Sidenote: American lives taken at at sea.] It is a war against all nations. American ships have been sunk, American lives taken, in ways which it has stirred us very deeply to learn of, but the ships and people of other neutral and friendly nations have been sunk and overwhelmed in the waters in the same way. There has been no discrimination. [Sidenote: Our motive vindication of human right.] The challenge is to all mankind. Each nation must decide for itself how it will meet it. The choice we make for ourselves must be made with a moderation of counsel and a temperateness of judgment befitting our character and our motives as a nation. We must put excited feeling away. 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. [Sidenote: Submarines are in effect outlaws.] [Sidenote: Must be dealt with on sight.] When I addressed the Congress on the 26th of February last I thought that it would suffice to assert our neutral rights with arms, our right to use the seas against unlawful interference, our right to keep our people safe against unlawful violence. But armed neutrality, it now appears, is impracticable. Because submarines are in effect outlaws, when used as the German submarines have been used against merchant shipping, it is impossible to defend ships against their attacks, as the law of nations has assumed that merchantmen would defend themselves against privateers or cruisers, visible craft giving chase upon the open sea. It is common prudence in such circumstances, grim necessity indeed, to endeavor to destroy them before they have shown their own intention. They must be dealt with upon sight, if dealt with at all. [Sidenote: Armed neutrality ineffectual]
