The reason for the creation of the United Nations was to protect world peace. Poverty is a leading reason wars and conflict in the world today. If everyone has enough food and a good place to live, they will be less likely to start conflicts in the future. The UN can help to make the world a more peaceful place by providing more international aid.
The mission of the United Nations is to bring together the resources of those countries with more and work in harmony to provide security and aid throughout the world. Those countries that are poorer should be the focus of this mission. Though they may not have money to contribute, these countries can be a part of the global community in other ways.
