ANKARA – 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.
