Canadian PM Mark Carney: The assumptions that had shaped decades of Canadian defense and foreign policy have been upended. Put another way, history is back with a vengeance. We face numerous and growing threats, from incursions in our Arctic to attacks in our cyberspace. The nature of warfare is changing rapidly, driven by a proliferation of drones, autonomous systems, hypersonic missiles, to name a few. More menacingly, authoritarian regimes are increasingly assertive. The burdens within our traditional alliances are shifting, and middle powers such as Canada are seeking greater strategic autonomy through partnerships amongst the like-minded. We must meet both the realities of a changing climate and that new geopolitical landscape.
