The principle of sovereignty is fundamental in international relations, as it asserts that states have the authority to govern themselves without external interference. This concept affects diplomatic interactions, where respect for national sovereignty can either facilitate or hinder cooperation among countries. While sovereignty supports state autonomy, it may also lead to conflicts when national interests clash. In a globalized world, however, issues like human rights, environmental concerns, and security threats challenge the primacy of sovereignty, prompting debates about intervention and the responsibilities of the international community.
