Final answer:
Territoriality and sovereignty are important core elements of today's political order as they provide a basis for the functioning of states and the international system, allowing states to govern their own affairs and protect their interests within their borders.
Step-by-step explanation:
Territoriality refers to the idea that states have defined boundaries and control over a specific geographic area. This allows states to govern their own affairs and protect their interests within their borders.
Sovereignty, on the other hand, refers to a state's ability to exercise supreme authority and make decisions without interference from other states. It allows states to have control over their own domestic and foreign policies, and ensures their independence.
These core elements of territoriality and sovereignty are important for maintaining order and stability in the international system. They provide a framework for interactions between states and help to prevent conflicts and ensure a peaceful coexistence.
