Characterized by many as historic, the summit is also expected to extend ongoing backing to Ukraine while advocating for peaceful resolutions. Notably, Spain has voiced dissent regarding the target increase to 3.5% by 2035, with further investments earmarked for defense-related projects. Spanish Economy Minister Carlos Cuerpo asserted that the debate surrounding this target is misguided, emphasizing Madrid’s current goal of achieving 2.1%. In contrast, Belgian Prime Minister Bart de Wever expressed a more optimistic outlook, deeming the 3.5% target a "realistic goal," despite some initial reservations.

As the summit commenced with an elegant dinner hosted by King Willem-Alexander and Queen Maxima, leaders gathered for a brief two and a half-hour dialogue, culminating in a concise communique. Rutte reminded fellow NATO members that they are convening at a particularly "dangerous moment," emphasizing the importance of mutual defense, famously encapsulated in the principle that "an attack on one is an attack on all."

Trump's participation marked his return to a NATO summit for the first time since 2019, following which he was scheduled to meet with Ukrainian President Volodymyr Zelensky. In discussing international conflicts, Trump notably focused more on issues in the Middle East rather than Ukraine's ongoing war. His earlier remarks questioning the foundations of NATO's Article Five, which guarantees mutual defense, drew scrutiny, prompting Rutte to reassure European allies of the solidity of the US commitment to the alliance.

UK Prime Minister Sir Keir Starmer affirmed NATO's ongoing relevance and unity, stating, "We live in a very volatile world..." While the summit has sparked debate regarding defense investments among member states, the overarching narrative revolves around upholding NATO's integrity and promoting collective strength in the face of emerging global challenges.
