The main concept is that of an international solidarity expressed in practice through worldwide division of labor: free trade is the principal point in the program of internationalism.
The growth of means of transport has created a world market and an opportunity for division of labor embracing all the developed and most of the undeveloped states.
Moreover, if the territorial state is to continue as the last word in the development of society, then war is inevitable.
It is characteristic that this should take place just when it is becoming more and more clear to all who think about the matter, that technically and economically we have left the territorial state behind us.
Today we stand on a bridge leading from the territorial state to the world community. Politically, we are still governed by the concept of the territorial state; economically and technically, we live under the auspices of worldwide communications and worldwide markets.
Every time economic and technical development takes a step forward, forces emerge which attempt to create political forms for what, on the economic-technical plane, has already more or less become reality.
