The international outlook of any community, at any stage in its development, is likely to be determined very largely by the interaction of four overlapping factors: geographic position with its strategic requirements; racial composition and resulting prejudices; economic interests, actual and potential, and, by no means least in importance, traditional policies and ideological trends. The relative strength of these several influences varies from period to period. Their individual content may change considerably under pressure of events either inside or outside the community, including the impact of party politics and of powerful personalities. They nevertheless have much to contribute to an understanding of the involved and complicated behaviour patterns of democratic societies in their relations with foreign states and peoples.
