ADMISSION OF NEW MEMBERS TO THE UNITED NATIONS
The experience of the inter war period in world organization was not lost upon the founders of the United Nations. The Second World War had made it unmistakably clear that a new world organization had to have behind its efforts the concentration of preponderant power, if it were to succeed in realising its supreme end, namely, the promotion and preservation of international peace. The presence of the United States and the Soviet Union was therefore essential to its success, if the United Nations was not to founder on the rock which had wrecked the League of Nations. It was not equally certain that, to be an effective instrument of peace, it must be universal in membership.
