The UN which emerged following World War II is a precursor to a global government. The birth of the global state necessitates the emergence of a global government. Our concern right now is the unity of nation-states that merge into a global state. Civilization has been moving towards this goal in so many ways. Global human unity has been the undeclared goal of humanity all through history and it has been unconsciously pursued thus far. The material and social benefits of global unity will be immense in terms of greater and more equal access to knowledge, power and wealth, but they will bring with them a new set of challenges to ensure that peace and security are not achieved at the expense of freedom, cultural diversity and the fullest development of individuality. Recurring war and violence, persistent poverty, financial instability, widening inequality, ecological destruction and climate change are some of the salient features which compel us to conclude that the continued evolution is both necessary and inevitable. The major challenges confronting humanity today all result from the inadequacy of a diverse community of sovereign nations competing with one another for power and advantage and their inability or unwillingness to act effectively and concertedly to address the problems of our collective existence.
But already there are signs that the process of social evolution will continue until it eventually results in some form of a unified world community. Humanity has evolved from the family and local community over millennia through several stages to finally create the present fractured and unstable global community of nearly 200 nation-states, some of which are barely a few decades old.
