According to IB: "Sovereignty characterizes a state’s independence, its control over territory and its ability to govern itself. How states use their sovereign power is at the heart of many important issues in global politics. Some theorists argue that sovereign power is increasingly being eroded by aspects of globalization such as global communication and trade, which states cannot always fully control. Others argue that sovereign states exercise a great deal of power when acting in their national interest and that this is unlikely to change."
