There are successful precedents for supra-national bodies  The history of the European Union (EU) in the post-World War II era provides an encouraging example of what might be done at the global level through a functioning world government. It is widely agreed among economists that the relatively high degree of prosperity and security enjoyed today by the people of the Western European nations is in no small measure the result of the gradual evolution from the original limited-purpose, six-member European Coal and Steel Community (ECSC) to the general-purpose, 27-member EU of today. In the early 1940s, many of the EU nations of today were locked in devastating warfare. The fact that these same nations are today harmonious components of a quasi-state polity demonstrates the capability of people to change their customary modes of thought and behavior when there exists a sufficient incentive to do so.
