Might is at once the supreme right, and the dispute as to what is right is decided by the arbitrament of war.

War gives a biologically just decision, since its decisions rest on the very nature of things.
Just as increase of population forms under certain circumstances a convincing argument for war, so industrial conditions may compel the same result.
In America, England, Germany, to mention only the chief commercial countries, industries offer remunerative work to great masses of the population.

The native population cannot consume all the products of this work.

The industries depend, therefore, mainly on exportation.

Work and employment are secured so long as they find markets which gladly accept their products, since they are paid for by the foreign country.
But this foreign country is intensely interested in liberating itself from such tribute, and in producing itself all that it requires.
