With the imminent end of its combat role in Afghanistan, however, it is time to take stock of how Canada has adapted to the exigencies of the post-9/11 world and to consider the future directions for its foreign, defence, and security policies.

This timely exploration and re-assessment of Canada's approach to strategic affairs offers a diverse set of nuanced, sometimes controversial, and always insightful perspectives on the most pressing security challenges that Canada currently faces. Bringing together noted experts on these issues – including a Canadian Senator, a past Minister of National Defence, former high-level military officers, and top scholars - this collection provides powerful ideas and guidance for the difficult task of formulating an overarching national security strategy.
