This study delved into the United Nations Security Council (UNSC) as a vital organ of the UN, examining two models proposed by former United Nations Secretary-General Kofi Annan and assessing global reactions towards reforming the Security Council (SC) within the UN framework. Employing the interview method, insights were gathered from experts across diverse nations proficient in council reform and the potential inclusion of Nigeria and South Africa as prime candidates from Africa for permanent UNSC membership. Findings underscored that council reform holds promise for bolstering international peace and security, advocating for the democratization of the council through the inclusion of African and other regional representatives. Recommendations put forth emphasize the imperative for Nigeria, South Africa, and other African states to bolster diplomatic efforts, underscoring their capabilities and preparedness to the international community. Concurrently, emphasis is placed on enhancing domestic conditions encompassing economic development, democratization, human rights, and governance to bolster acceptance of the "big five" within the UNSC and the broader global community. Furthermore, in the event of UNSC reform stagnation, entities such as the European Union (EU), African Union (AU), or the Arab League are urged to fortify their capacities, potentially assuming greater roles in peacekeeping and security within their respective regions, either with or without UNSC directives. Heightened inequality within the council may prompt states to channel grievances through regional representatives, potentially alleviating pressure for UNSC reform, albeit potentially diminishing the council‘s stature.
