NATO has been transforming since its founding in 1949. It is currently in the midst of its post-Cold War, post-9/11 transformation from an Alliance focused on defending Europe to a broader security provider prepared to deal with new threats wherever they may come from. In this issue of NATO Review, contributors examine NATO's ongoing transformation from a wide range of perspectives.

Sten Rynning of the University of Southern Denmark sees NATO transformation as going beyond military modernisation to include building new global partnerships. Admiral Giampaolo di Paola, Chief of Defence Staff of Italy, sees transformation as a response to the new security revolution. Mario Bartoli, NATO Deputy Assistant Secretary General for Armaments and Counterterrorism Technology Coordinator, outlines Alliance capability improvement programmes. Former NATO Assistant Secretary General for Defence Investment Robert Bell of Science Applications International Corporation examines the challenges of setting up the NATO Response Force, the Alliance's vehicle for transformation. In the interview, General Lance Smith, Supreme Allied Commander Transformation, discusses military transformation and the role of his command within the Alliance. Jamie Shea, Head of Policy Planning at NATO, examines the Alliance’s potential role in energy security. Patrick Stephenson of the University of Maryland in Europe looks at the Alliance’s expanding role. David Yost of the Naval Postgraduate School in Monterey, California, analyses the issues surrounding missile defence. Richard Weitz of the Hudson Institute argues in favour of NATO establishing a formal dialogue with the Shanghai Cooperation Organization. And James Snyder from NATO's Public Diplomacy Division reviews three recent books examing what's at stake in Iraq.
