There is no popular support for such a body  There is too much economic, political and cultural heterogeneity in the contemporary world to permit the establishment of a democratically organized, authoritative and effective—yet benign—world govern­ment. This was especially the case during the Cold War era with its virulent opposition between communist and non-communist economic, political and social ideologies. But it is still the case. For example, if a democratic world government were established, it would likely want to create a global welfare state, but this would be unacceptable to citizens of the rich countries because of the excessive taxation necessary to provide welfare benefits to the citizens of the poor nations. Another possibility is that the world government would be effectively controlled by the rich nations (despite appearances of democracy), and thus it would implement policies of uncontrolled trade and investment. These would be unacceptable to the poor nations because they would be regarded as a return to the exploitative con­ditions of the colonial era. Thus a serious effort to establish a world government in the real world would almost certainly lead to widespread armed resistance, and this might well escalate into the very nuclear world war that the world government was supposed to prevent. That would be the ultimate irony.
