Realism-the view that war is inescapable in a system where sovereign states compete for power and advantage to one another's detriment-still dominates thinking about international relations. Ken Booth argues that, as world politics continue to surprise us, a worldview in which war is seen as a rational policy choice is unacceptable. It is too soon in history to conclude that the international system is necessarily a 'war system'. As states become less important in what has been called the 'new medievalism', he argues for decentralizing power even further towards a global civil society and a global community of communities. He quotes Oscar Wilde: 'A map of the world that does not include Utopia is not even worth glancing at.'
