B9 + Nordic Allies Summit Bucharest: 'NATO 3.0' Framing Adopted — Rutte Proposes 0.25% GDP Ukraine Military Pledge; Russia Designated 'Most Significant Threat'

On May 13, 2026, NATO Secretary General Mark Rutte attended the B9 + Nordic Allies Summit at Cotroceni Palace in Bucharest, Romania — hosted by President Nicusor Dan alongside Polish President Karol Nawrocki, Ukrainian President Zelensky, and allied delegations from Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Romania, Slovakia, and the Nordic states (Finland, Sweden, Norway, Denmark). The summit produced a joint declaration that marks a doctrinal shift in how allied nations describe the alliance's structural evolution. The declaration designated Russia 'the most significant and direct long-term threat' to the alliance — stronger language than previous NATO documents — and implicitly endorsed what analysts are describing as 'NATO 3.0': a framework acknowledging that European allies will take primary responsibility for European conventional defence, with the United States providing the nuclear deterrence umbrella and intelligence backstop. This is the first formal multi-nation summit document to codify the doctrinal recalibration driven by Trump's conditionality, the Germany troop withdrawal, and the Iran war rift. The summit's most operationally significant outcome was Rutte's formal proposal for all NATO members to commit 0.25% of GDP annually to Ukraine military assistance — a binding commitment designed to insulate Kyiv from US political volatility. At 2025 NATO aggregate GDP, this would yield approximately $143 billion per year: more than five times current US bilateral military aid levels and nearly six times the EU's existing €25B annual military assistance baseline. The proposal is expected to be debated at Helsingborg (May 21–22) and formalized at Ankara (July 7–8). Some internal resistance from southern allies (Spain, Italy) has been noted. In joint press statements with Romanian President Dan and Polish President Nawrocki, Rutte declared: 'We need a stronger Europe in a stronger NATO.' Ukrainian President Zelensky used the Bucharest platform to press for accelerated weapons deliveries, particularly long-range systems, and to push back against ceasefire proposals that would freeze the territorial status quo. The summit came 4 days after Rasmussen's 'disintegrating' declaration (May 9), 1 day after the EU FAC Defence emergency session (May 12), and 8 days before the Helsingborg emergency ministerial (May 21–22).
