The North Atlantic Treaty Organization, NATO, currently operates within the framework of a strategic concept that was agreed upon in 1999. Since then, the challenges faced by NATO have changed dramatically. The terrorist attacks of 9/11, wars in Iraq and Afghanistan, a shift from conventional to asymmetric warfare, NATO’s ongoing enlargement, new developments in communication technologies, and a re-assertive Russia have all played a role in changing the paradigms of the strategic partnership. Accordingly, NATO is now taking stock to re-articulate itself with a new Strategic Concept. In this issue of TPQ, we take a look at what this re-imagining of the Alliance will look like. We also are reminded of what is not changing –why NATO is still indispensable. In his article, Supreme Allied Commander Admiral James Stavridis underlines the perseverance of NATO’s values and resolve on “the long road to peace, security, and prosperity.”
