world is organized into nation-states. The
history of the 20th century, involving the two most destructive wars in
human history, and culminating in the development of nuclear weapons, which
have the potential for destroying the human race, has clearly shown that
nation-states are unable to prevent war.
Yet, they are the best institutions yet devised for keeping peace and meeting
the needs of people within national boundaries.
The world community has become linked together in a network of economic institutions which are larger than the nation-state and cannot be adequately regulated in the public interest by national governments.
Environmental problems and issues of resource and supply have arisen which are global in nature and beyond the capacity of the nation-state.
The inter-dependence of the world community requires global institutions with sovereignty at the international level.
