World peace is not a party question. [...] The structure of world peace cannot be the work of one man, or one party, or one Nation.
We can gain no lasting peace if we approach it with suspicion and mistrust or with fear. We can gain it only if we proceed with the understanding, the confidence, and the courage which flow from conviction. Fourth inaugural address (1945)
America's own rightful place in the world depends in large part upon how fully these and similar rights have been carried into practice for all our citizens. For unless there is security here at home there cannot be lasting peace in the world. State of the Union Address — Second Bill of Rights (1944)
