NATO Summit in Ankara Looms as Europe Seeks to Placate Trump Amid Iran War Bitterness and Spending Surge

NATO's 32 heads of state and government are set to gather in Ankara on July 7 and 8 for what Secretary General Mark Rutte has billed as a summit that will demonstrate Europe's seriousness as a defence actor — but which risks being overshadowed by simmering fury over the Iran war, President Trump's renewed complaints about burden-sharing, and unresolved questions about America's long-term commitment to European security. The summit, to be held at Turkey's Presidential Complex and only the second NATO summit hosted by Ankara after Istanbul in 2004, arrives at what the European Policy Centre called a critical moment for Euro-Atlantic security, coming in the fifth year of Russia's full-scale invasion of Ukraine and the immediate aftermath of the first major US-led war in the Middle East since Iraq. Reuters reported on Thursday that Trump took to Truth Social to complain the US was spending money to protect NATO members without receiving any benefit, hours after Rutte arrived in Berlin to marshal European enthusiasm for the gathering.

The transatlantic relationship has suffered two acute shocks in 2026 that will hang over the Ankara proceedings. According to Pakistan Today, the alliance faced crises this year over Trump's demands for ownership of Greenland, an autonomous territory of NATO-member Denmark, and his anger at European allies over their response to the war on Iran. France and Britain deployed forces to the Mediterranean and Red Sea during the conflict but did not participate in combat operations, a restraint that infuriated the Trump administration. The Conference Board noted that the US has also announced troop withdrawals from Europe, cut the forces assigned to NATO's defence plans including an aircraft carrier, refuelling aircraft, fighter jets and drones, and launched a six-month review of its military presence on the continent. Defence Secretary Pete Hegseth has threatened to withhold some US dues to NATO if allies deemed to be free-riding fail to meet spending commitments.

European capitals are hoping that defence spending data will serve as their most effective diplomatic currency in Ankara. Rutte announced last month that NATO's European members and Canada spent $90 billion more on defence in 2025 than the previous year, reaching a total of more than $570 billion. At the Hague summit in 2025, allies agreed to spend 3.5 percent of GDP on core defence items by 2035, up from the previous 2 percent target, with a further 1.5 percent earmarked for broader defence-related investments including cybersecurity. In Ankara, NATO members are expected to sign new contracts worth tens of billions of dollars, though officials from several member states have expressed frustration that industrial production has not scaled at the pace demanded, with some orders still taking years to fulfil. The Trump administration has pressed European governments to take primary responsibility for conventional defence as Washington pivots resources toward the Indo-Pacific.

Turkey's role as host lends the summit a particular strategic texture. The Carnegie Endowment for International Peace noted that Ankara sees the summit as an opportunity to leverage its credentials as a pivotal defence and security actor and retain a leading role in transatlantic security. Turkish Foreign Minister Hakan Fidan has observed that no ally can any longer rely on a single alliance as its sole organising principle, a sentiment echoed by Defence Minister Yasar Guler's argument that the era of absolute reliance on a single alliance is over. The CSIS framed the summit's central challenge as operationalising what it called NATO 3.0 — a more European NATO in which allies assume greater responsibility for their own defence — while keeping the United States committed to the alliance's Article 5 collective defence guarantee. Ukraine's President Volodymyr Zelensky is confirmed to attend, according to Politico, and the status of continued military assistance to Kyiv will be among the summit's most watched deliverables.

For all the emphasis on spending pledges and arms contracts, the summit's ultimate test will be political rather than financial. The Stratfor third-quarter forecast observed that transatlantic tensions are set to dominate the Ankara gathering, noting the compounding pressures of persistent energy-driven inflation, a fragile Middle East truce, and escalating regional pressures from Europe to Africa. European officials told Reuters they cannot be certain of a smooth summit given lingering bitterness over the Iran war and the president's habitual criticism of NATO. As one European diplomat told Reuters, the alliance is alive and kicking but a bit bruised. The deeper question — whether a US-led to a Europe-led NATO transition can be managed without opening a deterrence gap that Russia is eager to exploit — will not be resolved in Ankara, but the summit's tone and deliverables will signal how much runway remains before that question becomes urgent.
