ational disarmament, any more than complete unpreparedness
kept the United States out of the struggle. A reasonable armament
for every nation, and the union of all nations against any one or
two that threaten wantonly to break the peace is the most promising
plan intelligent pacifism has yet suggested. In such an
international system there will be room and plenty for submarines.

Indeed it is into just such a plan that they intelligently fit.
Though not wholly successful in their operations against capital
ships, they have demonstrated enough power to make nations hesitate
henceforth before putting a score of millions into ponderous
dreadnoughts which have to retire from submarine-infested waters as
the British did in their very hour of triumph at Jutland. They have
not nullified, but greatly reduced the value of overwhelming sea
power such as the British have possessed. A navy greater than those
of any two other nations has indeed kept the German ships, naval and
commercial, locked in port. But less than two hundred inexpensive
submarines bid fair to sweep the seas of all merchant ships--neutral
as well as British unless by feverish building the nations can build
ships faster than submarines can sink them. Huge navies may
henceforth be unknown.

The submarine has been the David of the war. It is a pity that its
courage and efficiency have been exerted mainly in the wrong cause
and that the missiles from its sling have felled the wrong Goliath.

Aircraft and submarine! It is still on the cards that when the
definitive history of the war shall be written, its outcome may be
ascribed to one or the other of these novel weapons--the creation of
American inventive genius.
