What is the difference between a one-world government and a federal world government?
Federal government is based on the principle that local communities are best at solving local problems, regional government at solving regional problems and national government at solving national problems. When a problem becomes too big or too taxing for one level of government such as national, defense or interstate trade, then it is delegated to the next level. World federal government is the application of this principle to problems, such as the environment or international terrorism, that do not respect national borders or sovereignty and cannot be solved by individual nations.
