Nations join international organizations so that they could

Nations join international organizations to advance their interests. International organizations provide platforms for member states to cooperate and work towards achieving common goals. Through these organizations, countries can negotiate on important global issues, form alliances, and establish rules and regulations that benefit them. Additionally, membership in international organizations can enhance a country's status and influence on the world stage. While foreign aid may be a potential benefit of membership, it is not the primary reason why nations join international organizations. Similarly, becoming more developed is not necessarily a direct outcome of joining such organizations.
