side there is the Four Nations Initiative, a cooperation project by Chile, South Africa, Sweden and Thailand to promote governance and management reforms, aiming at increased accountability and transparency. Democracy reform Another frequent demand is that the UN become "more democratic", and a key institution of a world democracy. This raises fundamental questions about the nature and role of the UN. The UN is not a world government, rather a forum for the world's sovereign states to debate issues and determine collective courses of action. A direct democracy would request the presidential election of the UN Secretary-General by direct vote of the citizens of the democratic countries (world presidentialism) as well as the General Assembly (just as cities, states and nations have their own representatives in many systems, who attend specifically to issues relevant to the given level of authority) and the International Court of Justice. Others have proposed a combination of direct and indirect democracy, whereby national governments might ratify the expressed will of the people for such important posts as an empowered World Court. Calls for diversity and democracy Implementation of population-based UN voting also raises the problems of diversity of interests and governments of the various nations. The nations in the UN contain representative democracies as well as absolute dictatorships and many other types of government. Allowing large powers to vote their population's interests en bloc raises the question of whether they would really represent the interests and desires of their individual citizens and the world community. Anything like direct election would be impossible as well in the many nations where an accurate direct vote would be impossible or where the local government has power to influence the local voters as well as security of the ballot box. Giving the UN any kind of actual governance power raises the question of how these powers could be carried out. What would happen when a vote of the UN General Assembly demands changes in the borders or political status of a nation, or requires citizens in some nations to tax themselves in favor of other nations, or demands the arrest of the leader of a nation, and is met by refusal? The subsidiarity principle resolves some of these issues. The term originates from social thought within the Catholic Church and states that no larger organ shall resolve an issue that can be resolved at a more local level. It
