This work explores whether the nation-state is a useful concept under contemporary international law. It begins with an analysis of Grotius' work, ""The Law of War and Peace"", tracing the historical development of the nation-state. It then argues that, due to increased interdependence among the peoples of the world, the nation state has become dysfunctional in serving the needs of global life. Emphasizing a world without borders, the book offers the concept of the Free State that allows the free movement of goods, services, capital, information and the peoples of the world.;This book is intended for international legal scholars, diplomats, policy-makers and foreign-affairs experts.
