The Second World War caused enormous destruction and left large parts of the world in ruins. That's why the United Nations was established with one main target to prevent war in the future. The UN is a meeting point where leaders from all around the world can interact. In the UN, countries try to agree on which rules and agreements should apply in the world. The most important topics of discussion in the UN are peace and security, human rights, and sustainable development. The Sustainable Development Goals is the United Nations Global Agenda to End Poverty, Fight In Equality, and Combat Climate Change by 2030. There are 17 goals in 169 targets. The Agenda serves as a joint roadmap for all the countries in the world. One of the main principles of the Sustainable Development Goals is to lead no one behind. The most vulnerable should be given priority. In the UN General Assembly, all countries, small and large, have one vote and the same say. All member states are committed to follow the Constitution of the United Nations, the UN Charter, where peace and human rights are central topics. The most powerful organ of the UN is the Security Council. It's in charge of maintaining peace and security between nations. The council has 15 members, five of which are permanent, and the remaining 10 members are elected for two-year terms. Even though the UN is the most important organization working for world peace today, it also receives criticism for its shortcomings in the face of modern-day conflicts. Many argue that the organization needs to change to remain important in the future. The UN General Secretary has called for major reforms of the organization. Several member states have supported change to maintain world peace and years to come. No matter how you look at it, the UN is one of the most important meeting points in the world, as well as an arena for international cooperation. To know the UN isn't perfect, it is the best we've got. And all nations must work together to take care of our world.
