There can be no peace in the world so long as a large proportion of the population lack the necessities of life and believe that a change of the political and economic system will make them available. World peace must be based on world plenty.
After the First World War the economic problem was no longer one of production. It was the problem of finding markets to get the output of industry and agriculture dispersed and consumed.
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.
During the last war when there was a market for everything that could be produced, the production capacity of Canada and the United States, which were outside the battle area, increased one hundred percent.
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.
Science has produced such powerful weapons that in a war between great powers there would be neither victor nor vanquished. Both would be overwhelmed in destruction.
Some think the worst horrors of war might be avoided by an international agreement not to use atomic bombs. This is a vain hope.
The history of our civilization has been one of intermittent war.
In the last five or six thousand years, empires one after another have arisen, waxed powerful by wars of conquest, and fallen by internal revolution or attack from without.
Some wars have been due to the lust of rulers for power and glory, or to revenge to wipe out the humiliation of a former defeat.
The increase of territory and power of empires by force of arms has been the policy of all great powers, and it has always been possible to get the approval of their state religion.
In the last fifty years science has advanced more than in the 2,000 previous years and given mankind greater powers over the forces of nature than the ancients ascribed to their gods.
However difficult it may be to bring it about, some form of world government, with agreed international law and means of enforcing the law, is inevitable.
In recent times, European nations, with the use of gunpowder and other technical improvements in warfare, controlled practically the whole world. One, the British Empire, brought under one government a quarter of the earth and its inhabitants.
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.
