Among the favourable signs are the steadily growing strength of the steps towards world order taken initially near the beginning of this century in the creation of the League of Nations, succeeded by the more broadly based United Nations Organization; the achievement since the Second World War of independence by the majority of all the nations on earth, indicating the completion of the process of nation building, and the involvement of these fledgling nations with older ones in matters of mutual concern; the consequent vast increase in co-operation among hitherto isolated and antagonistic peoples and groups in international undertakings in the scientific, educational, legal, economic and cultural fields; the rise in recent decades of an unprecedented number of inter-national humanitarian organizations; the spread of women's and youth movements calling for an end to war; and the spontaneous spawning of widening networks of ordinary people seeking understanding through personal communication.
