Outgoing Dutch Prime Minister Mark Rutte on Thursday clinched the race to become the next head of NATO after sole challenger Romanian President Klaus Iohannis pulled out.
The veteran politician, 57, is expected to be formally named by NATO's 32 nations in the coming days and should take over when current chief Jens Stoltenberg's term ends on October 1 after a decade in charge.
Rutte will come in at a perilous moment for the Western allies as Russia's war in Ukraine drags on and Donald Trump battles to reclaim the presidency in the United States come November.
After staking his claim for the job last year following the collapse of his coalition, staunch Ukraine backer Rutte quickly won the support of heavyweights the United States, Britain, France and Germany.
But he had to use all the diplomatic skills gleaned during almost 14 years in charge of the Netherlands to win over hold-outs led by Türkiye and Hungary.
Rutte overcame Turkish reticence with an April visit to Istanbul, before finally sealing a deal with Hungary's Viktor Orban at a European Union summit this week.
That left the last sticking point as Iohannis, whose surprise bid had ruffled feathers among allies banking on a smooth appointment for Rutte ahead of a NATO summit in Washington next month.
Diplomat and officials at NATO said a meeting of alliance ambassadors would likely be convened next week to approve Rutte's appointment.
As it announced Iohannis's decision, Romania's supreme defense council said it would donate one of the country's two operational Patriot systems to Ukraine, responding to pleas from Kyiv to its allies for more air defense assistance.
Ukrainian President Volodymyr Zelenskiy said Romania's decision "will bolster our air shield and help us better protect our people and critical infrastructure from Russian air terror".
The supreme council, which is chaired by Iohannis, said the president had informed NATO last week of his decision to withdraw and Romania would now support Rutte's candidacy.
Under Rutte, the Netherlands has in recent years ramped up defense spending above NATO's target of 2% of GDP. It is providing F-16 fighter jets, artillery, drones and ammunition to Kyiv as well as investing heavily in its own military.
