OWG meaning in Governmental ?

World government, global government or cosmocracy is the concept of a common political authority for all of humanity, giving way to a global government and a single state or polity with jurisdiction over the entire human world. Such a government could come into existence through violent and compulsory world domination or through peaceful and voluntary supranational union.

There has never been an executive, legislature, judiciary, military, or constitution with global jurisdiction. The world's largest and most powerful international organisation, the United Nations–beyond the United Nations Security Council (which can issue mandatory resolutions backed by its member states)–is limited to a mostly advisory role, and its stated purpose is to foster cooperation between existing national governments rather than exert authority over them.

Numerous fictional depictions exist however, such as the World State in Brave New World, the "Dictatorship of the Air" in H. G. Wells The Shape of Things to Come, and the United Nations in James S.A Corey's The Expanse.
