 The aim of much normative theorizing about global institutions and global justice is to interrogate whether a world government is feasible, desirable, or necessary for realizing human aspirations for just, inclusive, peaceful, and prosperous relations between the diverse individuals and groups that comprise a common moral community of humankind. Some think that the idea of world government involves a paradox: however it is conceived institutionally, when the winning conditions exist for establishing a desirable form of world government—one that will guarantee human security with individual liberty, protect the environment, and advance global social justice—it will no longer be necessary (Nielsen 1988: 276). Once all governments, especially the most powerful ones, are willing to use their power to build government networks that promote global peace, justice and environmental protection, and to cede some traditional rights of sovereignty to supranational institutions in areas such as the use of military force, the management and protection of the environment and natural resources, and the distribution of wealth, the establishment of a global political authority might seem superfluous. As Alexander Wendt has pointed out, however, a stable end-state of world order development requires such ideal conditions, should they ever develop, to become institutionalized into a world state that enacts “a global monopoly on the legitimate use of organized violence” (1988: 491); enforcement mechanisms are not superfluous, since there is always the possibility of violations by outlaw states and groups. In a similar vein, the Swedish philosopher Torbjörn Tännsjö has argued that neither voluntary multilateral cooperation under conditions of anarchy, nor a hybrid arrangement of “shared sovereignty between the world government and nation-states”, will be effective in resolving contemporary challenges in the realms of human security, global justice and the environment (2008: 122–125). Since sovereignty is indivisible, Tännsjö posits that a world state must have ultimate decision-making authority over nation-states over jurisdictional issues:
