11 Public life is so enveloped, even at the present hour, by the dense fog of mutual hatreds and grievances that it is almost impossible for the common people so much as freely to breathe therein. If the defeated nations continue to suffer most terribly, no less serious are the evils which afflict their conquerors. Small nations complain that they are being oppressed and exploited by great nations. The great powers, on their side, contend that they are being judged wrongly and circumvented by the smaller. All nations, great and small, suffer acutely from the sad effects of the late War. Neither can those nations which were neutral contend that they have escaped altogether the tremendous sufferings of the War or failed to experience its evil results almost equally with the actual belligerents. These evil results grow in volume from day to day because of the utter impossibility of finding anything like a safe remedy to cure the ills of society, and this in spite of all the efforts of politicians and statesmen whose work has come to naught if it has not unfortunately tended to aggravate the very evils they tried to overcome. Conditions have become increasingly worse because the fears of the people are being constantly played upon by the ever-present menace of new wars, likely to be more frightful and destructive than any which have preceded them. Whence it is that the nations of today live in a state of armed peace which is scarcely better than war itself, a condition which tends to exhaust national finances, to waste the flower of youth, to muddy and poison the very fountainheads of life, physical, intellectual, religious, and moral.
