The principle of non-intervention in foreign policy asserts that states should respect each other's sovereignty and refrain from interfering in domestic affairs. This principle underlines the importance of international law and recognizes the rights of nations to govern themselves without external coercion or influence. Non-intervention promotes diplomatic relations and helps prevent conflicts arising from external pressures. However, challenges arise when humanitarian crises occur, raising ethical questions about the international community's responsibility to intervene for humanitarian reasons. Balancing respect for sovereignty with moral obligations remains a complex issue in global politics.
