As I have tried to show, science, in producing the airplane and the wireless, has created a new international political environment to which governments must adjust their foreign policies.

Empires won by conquest have always fallen either by revolt within or by defeat by a rival.

It is said that those whom the gods wish to destroy they first make mad. It may well be that a war neurosis stirred up by propaganda of fear and hatred is the prelude to destruction.

When the Industrial Revolution of the nineteenth century brought a rapid increase in wealth, the demand of workers for a fair share of the wealth they were creating was conceded only after riots and strikes.

As we have seen, the wireless and the airplane have made the world so small and nations so dependent on each other that the only alternative to war is the United States of the World.

Some think the worst horrors of war might be avoided by an international agreement not to use atomic bombs. This is a vain hope.

Nearly every country in the world is now becoming industrialized as rapidly as it can.
