The concept of state sovereignty significantly affects international relations by affirming a nation's authority to govern itself without interference from external entities. This principle allows states to make independent decisions regarding their domestic and foreign policies, contributing to global political dynamics. However, state sovereignty can lead to tensions when sovereign interests conflict with human rights obligations or international norms. It also complicates interventions in failed states or during humanitarian crises, as the sovereignty of nations often limits external actions, highlighting the delicate balance between respecting autonomy and addressing global challenges.
