# Geopolitics Geopolitics is the study of how geography, resources, and power shape the behavior of states and the structure of international order. It emphasizes the material and strategic factors—territory, energy, trade routes, military positioning—that drive competition among nations, in contrast to approaches that foreground ideology or institutions. In the current era, geopolitics is defined by great-power competition among the United States, [[Russia]], and [[China]], with flashpoints including [[Ukraine]], [[NATO]] expansion, and control over global trade and technology supply chains. The framework's roots in [[Cold War]] realism have made it central to debates over American foreign policy, from interventionism to restraint, and it intersects with economic concerns like energy dependence and [[Antitrust]] policy toward globally dominant firms.
