Global political developments in recent years have demonstrated complex dynamics, and recent actions by the UN reflect ongoing efforts to address these challenges. In this context, UN missions often involve diplomacy, humanitarian assistance and sustainable development. One of the important steps taken by the UN is increasing involvement in the issue of climate change. The COP26 Climate Change Conference in Glasgow in 2021 was a major highlight, with member countries committing to reducing carbon emissions and achieving net-zero by 2050. The UN is also strengthening initiatives such as the 2030 Agenda for Sustainable Development, which aims to tackle poverty and inequality around the world. In addition, the UN is active in resolving armed conflicts in various parts of the world. Through the United Nations Peacekeeping Operations (PKO), the UN has deployed peacekeeping forces in countries experiencing crises, such as Mali and the Central African Republic. Recent reports show positive results from these missions, with reduced levels of violence in areas that had stabilized. UN action is also seen in efforts to uphold human rights. Through the UN Human Rights Council, various resolutions were introduced to address human rights violations, especially in countries experiencing political crises, such as Myanmar and Venezuela. Independent investigations into violations that occur seek to ensure accountability for perpetrators. Another important aspect is the UN’s efforts to handle global health issues, especially in the midst of the COVID-19 pandemic. Through COVAX, the UN plays a role in the fair distribution of vaccines to developing countries. This commitment aims to ensure all countries, regardless of their economic situation, can access vaccines and build resilience against infectious diseases. In the context of global politics, the UN also seeks to strengthen dialogue between countries through multilateral forums. Meetings such as the UN General Assembly provide a platform for countries to voice their national interests while encouraging international cooperation on global issues. Going forward, UN action in addressing these challenges will focus on policy innovation and increased collaboration with non-state actors, including the private sector and civil society. This will be important in dealing with complex issues such as the climate crisis and social injustice that require comprehensive solutions. With the various steps taken, the UN remains a key institution in responding to global political shifts. Continuing to adapt to changing realities and strengthening international cooperation is key to achieving peace and sustainable development throughout the world. The success of the UN will depend heavily on the active participation and commitment of its member states in promoting broader stability.
