geostrategy

Geostrategy, a subfield of geopolitics, is a type of foreign policy guided principally by geographical factors as they inform, constrain, or affect political and military planning. As with all strategies, geostrategy is concerned with matching means to ends. Strategy is as intertwined with geography as geography is with nationhood, or as Colin S. Gray and Geoffrey Sloan state it, "[geography is] the mother of strategy."

Geostrategists, as distinct from geopoliticians, approach geopolitics from a nationalist point of view. Geostrategies are relevant principally to the context in which they were devised: the strategist's nation, the historically rooted national impulses, the strength of the country's resources, the scope of the country's goals, the political geography of the time period, and the technological factors that affect military, political, economic, and cultural engagement. Geostrategy can function prescriptively, advocating foreign policy based on geographic and historical factors, analytically, describing how foreign policy is shaped by geography and history, or predictively, projecting a country's future foreign policy decisions and outcomes.
