We fully realize today that victory in war requires a mighty united effort. Certainly, victory in peace calls for, and must receive, an equal effort. Man has learned long ago, that it is impossible to live unto himself. This same basic principle applies today to nations. We were not isolated during the war. We dare not now become isolated in peace.
