rivalry, however, does not take place under the same conditions as the
intrasocial struggle, and therefore cannot lead to the same results.
Above the rivalry of individuals and groups within the State stands the
law, which takes care that injustice is kept within bounds, and that the
right shall prevail. Behind the law stands the State, armed with power,
which it employs, and rightly so, not merely to protect, but actively to
promote, the moral and spiritual interests of society. But there is no
impartial power that stands above the rivalry of States to restrain
injustice, and to use that rivalry with conscious purpose to promote the
highest ends of mankind. Between States the only check on injustice is
force, and in morality and civilization each people must play its own
part and promote its own ends and ideals. If in doing so it comes into
conflict with the ideals and views of other States, it must either
submit and concede the precedence to the rival people or State, or
appeal to force, and face the risk of the real struggle--i.e., of
war--in order to make its own views prevail. No power exists which can
judge between States, and makes its judgments prevail. Nothing, in fact,
is left but war to secure to the true elements of progress the
ascendancy over the spirits of corruption and decay.

It will, of course, happen that several weak nations unite and form a
superior combination in order to defeat a nation which in itself is
stronger. This attempt will succeed for a time, but in the end the more
intensive vitality will prevail. The allied opponents have the seeds of
corruption in them, while the powerful nation gains from a temporary
reverse a new strength which procures for it an ultimate victory over
numerical superiority. The history of Germany is an eloquent example of
this truth.

Struggle is, therefore, a universal law of Nature, and the instinct of
