Geopolitics is the study of how geographical factors influence political power and international relations. It examines how location, resources, and physical terrain affect the behavior of countries and their interactions with one another. For example, countries with abundant natural resources, like Saudi Arabia with its oil reserves, often have significant influence on global markets. Additionally, geopolitics considers historical events and cultural factors that shape national interests. The relationships between nations, such as the United States and China, are often influenced by their geographic proximity, economic ties, and military strategies. Understanding these dynamics helps explain global conflicts and alliances.
