The significance of international law in politics lies in its role as a framework for maintaining order and cooperation among nations. It governs relations through treaties, agreements, and customs, promoting principles like sovereignty and human rights. International law can help prevent conflicts, regulate conduct in war, and foster economic relations, impacting global stability. Moreover, adherence to international law enhances a country's reputation and diplomatic standing. Violating these norms can lead to sanctions and isolation, underlining the importance of legal frameworks in shaping political behaviors and alliances.
