Is there a justification for European integration? "The Idea of a European Superstate" examines this - the most basic - question raised by the European Union. In doing so, Glyn Morgan assesses the arguments put forward by eurosceptics and their critics. In a challenge to both sides of the debate, Morgan argues in support of a European superstate. Unless Europe forms a unitary sovereign state, Europe will remain, so he maintains, weak and dependent for its security on the United States. "The Idea of a European Superstate" reshapes the debate on European political integration. It throws down a gauntlet to eurosceptics and euro-enthusiasts alike. While employing the arguments of contemporary political philosophy and international relations, this book is written in an accessible fashion that anyone interested in European integration can understand.
