The Nazi Party of Germany envisaged the establishment of a world government under the complete hegemony of the Third Reich. In its move to overthrow the post-World War I Treaty of Versailles, Germany had already withdrawn itself from the League of Nations, and it did not intend to join a similar internationalist organization ever again. In his stated political aim of expanding the living space ("Lebensraum") of the Germanic people by destroying or driving out "lesser-deserving races" in and from other territories, dictator Adolf Hitler devised an ideological system of self-perpetuating expansionism, in which the growth of a state's population would require the conquest of more territory which would, in turn, lead to a further growth in population which would then require even more conquests. In 1927, Rudolf Hess relayed to Walther Hewel Hitler's belief that world peace could only be acquired "when one power, the racially best one, has attained uncontested supremacy". When this control would be achieved, this power could then set up for itself a world police and assure itself "the necessary living space... The lower races will have to restrict themselves accordingly".
