The Indian Ocean and the Superpowers (1986) provides an analysis of the evolution of superpower strategy and interests in the Indian Ocean. It argues that the priorities of the United States and the Soviet Union are to safeguard their own economic, strategic and security interests by containing local conflicts, controlling arms escalation and obtaining bases. Each has promoted a network of dependency relationships to which they act as patrons, providing security and certain commitments in return for trade, resources and profit.
