The global political system, Palgrave Macmillan, Houndmills, Basingstoke, Hampshire, UK, 2011, ISBN 978-1-4039-9587-2

  • Elegantly synthesising history and theory, this text introduces the concepts that have been used to explain the politics and policies of the global system. It challenges the dominance of purely state-based approaches and shows how non-state-based approaches are essential for a full and integrated understanding of today’s global politics. Using both approaches, the author examines key issues in contemporary world politics, from international security to economic stability and migration to human rights.
