Former U.S. Ambassador to NATO Kurt Volker lauded the 2026 NATO Summit in Ankara, Turkey, as a success, particularly highlighting former President Donald Trump's role in pressuring NATO allies to boost their defense spending. Volker noted a significant shift in attitude among allies, attributing this to Trump's persistent calls for increased contributions, a goal consistent with American presidential objectives since the Eisenhower administration. He described a "victory lap" opportunity for Trump due to these increased commitments.

The summit saw NATO members collectively commit to substantial defense initiatives. Allies pledged €70 billion ($80 billion) in military equipment, training, and assistance to Ukraine for 2026, with a similar package projected for 2027. Additionally, over $50 billion in new defense procurements were announced, alongside commitments to expand manufacturing capacity, accelerate innovation, and remove defense trade barriers among allies. European members and Canada alone increased investments in core defense requirements by over $139 billion in the past year.

A pivotal outcome for Ukraine was the potential for licensed production of Patriot missile interceptors, an idea floated by Trump during his meeting with Ukrainian President Volodymyr Zelenskyy. However, local production of these critical systems is not expected to materialize until at least 2028, leaving Ukraine vulnerable to ballistic missile threats in the short term. Despite this, Ukraine also secured drone deal agreements with Denmark, Estonia, and the Netherlands to deepen defense-industrial cooperation. NATO reaffirmed its unwavering support for Ukraine's freedom and territorial integrity, referencing Kyiv as a contributor to "transatlantic security."

Beyond Ukraine, the summit reinforced NATO's collective defense principle, with leaders reaffirming their "ironclad commitment" to Article 5 of the Washington Treaty. The Ankara Declaration emphasized unity, solidarity, and collective strength as the foundation of peace and security. Allies also agreed to continued investment in advanced military capabilities, including deep precision strikes, integrated air and missile defense, and uncrewed systems. The summit acknowledged Russia as a long-term threat to Euro-Atlantic security and terrorism as a persistent challenge, while also calling on Iran to respect freedom of navigation in the Strait of Hormuz.
