49. The United Nations can be of great assistance in establishing an armistice and in maintaining a certain measure of tranquillity in the Middle East. The past twenty years have shown, however, that all efforts in this respect have not been sufficient to bring peace to the area, nor to prevent the recurrent outbreak of hostilities. We must realize that in the last resort a peaceful settlement in the Middle East will be possible only if the nations of the area themselves are willing to co-operate in this effort.
