The principle at hand refers to the idea that a state has the right to exercise exclusive control over a defined geographic area. This encompasses land, internal waters, and territorial seas, and often extends to the airspace above. It suggests that these boundaries should be respected by all other states. An instance of this is when one nation refrains from military actions or political interference within the internationally recognized borders of another.
Observance of this principle is a cornerstone of international relations and a crucial factor for maintaining global stability. Respect for established boundaries can prevent conflicts, foster peaceful coexistence, and facilitate international cooperation. Historically, violations of this concept have often led to armed conflicts, political instability, and humanitarian crises, highlighting the importance of upholding it in the international arena. It reinforces the foundational concept of state sovereignty.
