U.S. President Donald Trump has reignited tensions with NATO allies, questioned the alliance’s reliability, and announced a new security-oriented framework concerning Greenland during meetings at the World Economic Forum in Davos, officials and media reports said.
The remarks and announcements come amid renewed transatlantic strain following Trump’s criticism of NATO’s past military role, his suggestion that the alliance could be used to secure the U.S. southern border, and ongoing negotiations over Arctic security cooperation.
NATO reliability questioned
In an interview with Fox News on Thursday, January 22, Trump said he was “not sure” NATO members would come to the United States’ defence if it were under threat.
He also claimed that NATO allies deployed to Afghanistan “stayed a little back, a little off the front lines,” casting doubt on their combat contributions during the two-decade-long war.
The comments prompted swift backlash in Britain. UK Social Care Minister Stephen Kinnock described the remarks as “deeply disappointing” and “plainly wrong,” noting that 457 British service members were killed during the Afghanistan conflict.
Emily Thornberry, chair of the UK Parliament’s Foreign Affairs Select Committee, called the comments an “absolute insult” to allied forces, stressing that NATO’s Article 5 collective defence clause has been invoked only once — after the September 11 attacks on the United States.
Several British lawmakers with military backgrounds echoed the criticism, saying the remarks dismissed the sacrifices made by allied troops.
Greenland ‘framework’ announced
Despite the controversy, Trump announced what he described as a diplomatic breakthrough following a meeting in Davos with NATO Secretary-General Mark Rutte.
In a post on Truth Social, Trump said the two leaders had agreed on a “framework of a future deal” regarding Greenland and broader Arctic security cooperation. As part of the understanding, Trump said he would suspend previously threatened tariffs of between 10% and 15% on European allies, which had been due to take effect on February 1.
Trump has previously suggested purchasing Greenland outright. However, officials familiar with the discussions said the new framework focuses on security coordination in the Arctic rather than territorial acquisition.
The talks reportedly centre on preventing Russia and China from establishing military or economic footholds in the region and include preliminary discussions on a proposed “Golden Dome” missile defence system.
No formal agreement has been signed, and negotiations are expected to continue in the coming weeks.
Article 5 and border proposal
Further controversy followed on January 23 after Trump suggested on social media that the United States should have “tested” NATO by invoking Article 5 to help secure the U.S. southern border.
Trump argued that NATO forces could have been deployed to counter what he described as “invasions of illegal immigrants,” allowing U.S. Border Patrol agents to be reassigned elsewhere.
European officials and international law experts dismissed the idea, noting that Article 5 applies only to external armed attacks against member states and does not cover domestic law enforcement or immigration enforcement.
Military service record revisited
Trump’s criticism of allied military performance also prompted renewed attention to his own military record.
UK Liberal Democrat leader Sir Ed Davey noted that Trump received five deferments during the Vietnam War — four for educational reasons and one for a medical diagnosis of bone spurs — an issue that has long been a point of political debate.
Afghanistan war casualties
Official figures from the NATO-led Afghanistan mission between 2001 and 2021 highlight the scale of allied involvement:
Country | Fatalities
United States | 2,461
United Kingdom | 457
Canada | 158
France | 90
Denmark | 44 (highest per capita)
Trump’s renewed questioning of NATO’s commitments, alongside the unveiling of a new Arctic security framework, signals a complex recalibration of U.S.-European relations.
While the Greenland initiative suggests continued scope for cooperation, the president’s remarks have reopened sensitive debates over alliance trust, shared military sacrifice and the future scope of NATO’s mission.
European leaders are seeking further clarification on the Greenland framework, while pressing Washington for assurances on its long-term commitment to the alliance.
