But as yet there has been only a rudimentary beginning of the development of international tribunals of justice, and there has been no development at all of any international police power.

Now, as I have already said, the whole fabric of municipal law, of law within each nation, rests ultimately upon the judge and the policeman; and the complete absence of the policeman, and the almost complete absence of the judge, in international affairs, prevents there being as yet any real homology between municipal and international law.
Moreover, the questions which sometimes involve nations in war are far more difficult and complex than any questions that affect merely individuals.

Almost every great nation has inherited certain questions, either with other nations or with sections of its own people, which it is quite impossible, in the present state of civilization, to decide as matters between private individuals can be decided.

During the last century at least half of the wars that have been fought have been civil and not foreign wars.

There are big and powerful nations which habitually commit, either upon other nations or upon sections of their own people, wrongs so outrageous as to justify even the most peaceful persons in going to war.
