International law differs from domestic law in its applicability and enforcement mechanisms. International law governs the relations between states and is derived from treaties, custom, and general principles recognized by nations. In contrast, domestic law pertains to the rules and regulations within a single country's jurisdiction, enforced by that country’s legal system. While international law relies on voluntary compliance and diplomatic resolutions, domestic law has coercive authority, allowing for legal proceedings against individuals or entities violating laws. The interplay between the two systems is crucial for maintaining global order.
