frontiers are the outcome of chance, and are only temporary frontiers that have been established as the result of political struggles which took place at various times. The same is also true of the frontiers which demarcate the territories on which other nations live. And just as only an imbecile could look on the physical geography of the globe as fixed and unchangeable--for in reality it represents a definite stage in a given evolutionary epoch which is due to the formidable forces of Nature and may be altered to-morrow by more powerful forces of destruction and change--so, too, in the lives of the nations the confines which are necessary for their sustenance are subject to change.

State frontiers are established by human beings and may be changed by human beings.
