NATO leaders unveiled arms deals worth tens of billions of dollars in Turkey on Tuesday, driving home the message that they are heeding US calls to spend more to defend Europe even as President Donald Trump said he felt let down and renewed his push to control Greenland.
Leaders were convening for a summit in the capital Ankara, hoping to project unity after another bruising year, in which the Iran war once again exposed cracks in the alliance that has underpinned Western security since the end of World War Two.
In a meeting with President Tayyip Erdogan, Trump said he might have boycotted the NATO summit altogether had it not been for his warm relations with the Turkish leader, and did not rule out further troop withdrawals from Europe.
"Well, we're going to see. I was very disappointed with NATO," he said, singling out Britain, France, Germany and Italy for not doing enough to support the US war on Iran.
Trump added that "we weren't treated well" by the allies, even as he reiterated that he did not want or need their help.
"Before I asked, they said they wouldn't be there, and we've invested trillions of dollars in NATO," Trump said.
Trump said he had spoken to Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskiy before the summit about ending the war that started in February 2022 when Russia invaded its neighbor.
"I think they both want to make a deal. It's too bad it took so long ... Something's going to come out," Trump said.
While sharply criticizing longstanding allies, Trump announced Washington would lift sanctions on Turkey that were imposed in 2020 over Ankara's purchase of Russian air defense missiles. He also expressed a willingness to sell Turkey F-35 fighter jets.
The move would be a major gesture to Erdogan and remove a longstanding irritant in bilateral ties.
Rutte wants a defence industry revolution
NATO members have repeatedly tried to show Trump that they are stepping up.
NATO Secretary General Mark Rutte said on Monday that Europeans had made "staggering" increases in defense spending.
Before Trump's arrival, Rutte trumpeted a series of initiatives and deals at a defense industry forum, and called for a defense industry "revolution" across the alliance, warning over Russia's massive military spending as well as China, North Korea and Iran.
"We don't have the luxury of time. We need capabilities now to ensure we remain ready. The security situation demands it," Rutte said. "The hum of machinery must become a roar."
The deals, estimated to be worth at least $50 billion according to one NATO official, included European countries buying surveillance drones from US company Northrop Grumman NOC.N, and NATO buying planes from Sweden's Saab.
Saab shares at one point rose more than 5% as investors bet on the company benefiting from European rearmament. Morgan Stanley upgraded the stock.
Separately, the British government said in a statement that 12 European nations, including the UK, France and Germany, will spend more than $50 billion over the next 10 years to develop long-range precision weapons to strengthen NATO's defense capabilities.
Starmer will unveil the UK-led initiative in Ankara on Wednesday, and the countries are set to release a joint statement with additional details.
Europe's defense sector has often been criticized as fragmented and saddled with red tape and rivalries between companies and countries. That has left Europe more reliant on purchases of US weapons.
Weak economic growth and the need to maintain generous state welfare provisions have also made defense spending a tougher sell in Europe.
Iran war prompted Trump to revive criticism of NATO
Tensions within NATO, already strained over Ukraine and Trump's desire to wrest Greenland from fellow NATO member Denmark, have deepened since the US attacked Iran in February. Trump has repeatedly criticized NATO members for insufficient support in the conflict, threatening to quit the alliance.
On Tuesday, he renewed his push to wrest Greenland from Denmark.
"That should be controlled by the United States, not by Denmark," he said.
"That's what hurt my relationship with NATO, because Greenland doesn't help Denmark. Denmark doesn't spend money to really help Greenland, but it's an important part for the United States."
Speaking at the summit, Denmark's Prime Minister Mette Frederiksen said she expected allies to respect her country's sovereignty and accept that Greenland is not for sale.
European officials insist they largely honored commitments to let the US use their airspace and bases, despite not having been consulted about a deeply unpopular war that roiled their economies.
The US has also announced troop withdrawals from Europe and launched a six-month review of its military presence there.
European officials had said they were braced for a repeat of some of Trump’s recent criticism and could not be sure of a positive outcome, in part due to Trump's volatile relationship with some leaders, most recently seen in a feud with Italian Prime Minister Giorgia Meloni.
NATO members are expected to reaffirm support for Ukraine, with Zelenskiy urgently calling for more air defense supplies.
Underscoring the stakes, Russia hammered the Kyiv region with missiles and drones on Monday, killing at least 28 people and exposing Ukraine's critical shortage of US-made air-defense interceptors.
Summit declaration affirms commitment to collective defense
The 32 NATO leaders met for a dinner on Tuesday evening, but the main session of their summit takes place on Wednesday.
Ambassadors from all NATO members have approved a summit declaration that affirms an “ironclad commitment” to collective defense. But the declaration will only be issued after it has been endorsed by the leaders.
The Trump administration has pressed Europeans to boost defense spending and take on primary responsibility for the conventional defense of Europe as it seeks to shift its military focus to the Indo-Pacific.
The US has also announced troop withdrawals from Europe, cut the forces it assigns to NATO’s defense plans - including an aircraft carrier, refueling aircraft, fighter jets and drones - and launched a six-month review of its military presence on the continent.
European leaders say they are working to take on more responsibility for the continent’s security but want a predictable and orderly transition to avoid any gaps in their defenses that could be exploited by Russia.
