Stephen Saideman, Paterson Chair in International Affairs at the Norman Paterson School of International Affairs, joined us to unpack the key issues likely to shape discussions at the 2025 NATO Summit. Saideman discusses a potential new 3.5% GDP defence spending floor, the growing unreliability of the U.S. as a security partner, and the future viability of NATO’s Article Five without guaranteed American support. He also examines how President Trump’s return to power has impacted alliance cohesion, how Canada and Europe are adjusting their defence strategies, the subsequent European response through rearmament and strategic diversification, and whether NATO can maintain credibility and unity given increasing geopolitical uncertainty.
