Donald Trump and Volodymyr Zelensky are scheduled to meet at the 2026 NATO summit in Turkey, continuing a pattern of direct talks between the two leaders that has defined Ukraine diplomacy for the past year. The meeting comes after what news reports describe as an intense week of Russian attacks on Ukraine, though the summit's formal agenda remains largely undisclosed as of early July.

This gathering extends a chain of substantive encounters that began last September, when Trump and Zelensky first met on the margins of the UN General Assembly in New York. Since then, the two have connected multiple times: U.S. Secretary of the Army Daniel Driscoll visited Kyiv in November, Ukrainian and American officials held talks in Berlin in mid-December, and Trump and Zelensky sat down at Davos on January 22. Before arriving in Turkey, Zelensky also placed six calls to European leaders to coordinate his approach heading into his session with Trump.

Throughout these encounters, one question has remained unresolved: how much territory should Ukraine retain, and on what terms? At Davos, Zelensky acknowledged openly that the territorial issue remained unsettled even after his conversation with Trump, who described the meeting as "good" and called the broader negotiation "an ongoing process." That phrase—progress without closure—captures the state of U.S.-Ukraine diplomacy since Trump returned to office. Nothing in recent reporting suggests the territorial question has moved closer to settlement.

What has shifted is Ukraine's negotiating flexibility. In Berlin in December, Zelensky signaled a willingness to drop Ukraine's long-standing goal of joining NATO, while insisting on what he termed a "dignified peace." This concession marks a significant turn in Kyiv's strategy. For much of the war, NATO membership stood as a core demand. Now Ukraine appears willing to settle for security guarantees negotiated separately—bilateral commitments from the United States, agreements with a coalition of allied nations, or protections woven into NATO structures without formal membership.

Those security guarantees have a documented history. Trump told Zelensky in August 2025 that the United States would help ensure Ukraine's security in any peace agreement ending the war. What such a guarantee would actually look like—whether it takes the form of a binding bilateral pact, a coalition arrangement, or something else—has never been spelled out in public statements. The Turkey summit offers a moment for NATO allies to demand greater specificity.

NATO's institutional role has paralleled Trump's bilateral diplomacy. Secretary General Mark Rutte visited Zelensky in Kyiv shortly before NATO defense ministers met, a visit he confirmed in a February 12 press conference. Two months later, at a speech at the Reagan Institute's Center for Peace Through Strength in Washington, Rutte outlined the alliance's strategic direction ahead of the summit season. Between his Kyiv trip and that speech, Rutte has functioned as a bridge connecting Washington's one-on-one talks with Zelensky to the consensus-building process that NATO's thirty-two member states require.

The real situation is not a single negotiation approaching its climax but rather several overlapping discussions running in parallel. Trump's direct diplomacy with Zelensky has proceeded alongside NATO's broader institutional consultations, and alongside Zelensky's own outreach to European capitals. None of these tracks has yielded a public agreement on territory. What has emerged is evidence of Kyiv's willingness to move on membership—a shift that removes one sticking point from the table even as the harder question, occupied territory, stays in play.

For NATO members watching this unfold, the Turkey summit functions more as a checkpoint than a resolution point—a moment to measure where the bilateral and institutional tracks align and where they still separate. The recent escalation in Russian strikes adds pressure on both Trump and Zelensky to demonstrate forward movement, even if a territorial settlement remains out of reach. Whether that pressure produces anything beyond another statement about an "ongoing process" is what alliance members will be tracking closely.
