Finnish President Alexander Stubb discusses Finland’s concept of sisu—endurance, grit, and resilience—and how it shapes national security, diplomacy, and relations with Russia. In a wide-ranging interview, he outlines the stalled prospects for Ukraine peace talks, the need for stronger military and financial pressure on Russia, and Europe’s coordination with President Trump. Stubb also addresses corruption challenges in Ukraine, canceled Trump-Putin meeting plans, hybrid warfare threats, nuclear risks, and Finland’s comprehensive defense model. He emphasizes patience, unity, and calm strategic action as Europe navigates an increasingly unpredictable security environment.
