In everyday speech, the word “refugee” means any person who has to leave his home because of a general catastrophe — natural or social. People whose dislocation was caused, in one way or another, by the second world war came to be called “displaced persons” or “DP's.” The largest remaining group of such displaced persons is in China, where there are perhaps 25,000,000 people who are still living away from their former homes; but the problem which they present, though it is almost unimaginably vast and tragic, comes within the jurisdiction of a single nation. The same is true of the second largest remaining group, the perhaps 10,000,000 Soviet citizens who have not returned to their pre-war places of residence. The perhaps 8,000,000 Germans recently transferred from East Prussia, Silesia, the Sudetenland and other areas into the four zones of diminished Germany and Austria pose an international problem; but it is being handled by the occupying authorities — jointly or separately. Apart from several hundred thousand persons of Chinese nationality driven by the war from their homes in non-Chinese portions of Southeast Asia and some tens of thousands of Indian nationality, similarly displaced, who do not raise vexing political questions, the persons with whom a general international organization for uprooted people must deal are almost exclusively the perhaps 2,000,000 European refugees — refugees in the narrower technical meaning of the term, bristling with political complications.
