With the publication of Seapower: A Guide for the Twenty-First Century Geoffrey Till has set the standard for publications on all things maritime. The updated and expanded new edition of the book is an essential guide for students of naval history and maritime strategy and provides essential reading for those interested in the role of seapower in the twenty-first century. Till notes in the preface to the second edition of the book (p. xv) that he specifically aimed at providing a broader international context for the discussion of the role of navies. The naval policies of China, Japan, India and the United States are used as case studies of general naval developments around the world. In addition, the analysis highlights the “… post-modern preoccupations of today’s navies” (p. xvii) including inter alia the maintenance of good order at sea, coalition operations, and multilateral terrorism. The central hypothesis of the book is rooted in the notion that the sea is central to the prosperity and security of all nations, and even more so since the emergence of an increasingly globalised world trading system. Till argues in Seapower that the fate of nations is closely link to the sea as a source of resources and as a means of transportation, information exchange and strategic domination in all human development.
