LONDON — European diplomacy has undergone a radical transformation in its approach to dealing with President Donald Trump, shifting from appeasement tactics to firm opposition. The catalyst for this dramatic change emerged when Trump renewed demands for U.S. acquisition of Greenland, a semi-autonomous territory under Denmark’s sovereignty and NATO ally.
The previously accommodating European leaders have abandoned their flattering approaches and royal treatment diplomacy. Instead, they’ve established clear boundaries against what they perceive as Trump’s disregard for international norms and territorial sovereignty. British Prime Minister Keir Starmer declared that ‘Britain will not yield’ on supporting Greenland’s sovereignty, while Norwegian Prime Minister Jonas Gahr Støre emphasized that ‘threats have no place among allies.’
This diplomatic hardening occurred during the World Economic Forum in Davos, Switzerland, where multiple European nations collectively rejected Trump’s demands regarding Greenland and his proposed ‘Board of Peace’ initiative. Danish Prime Minister Mette Frederiksen noted the significance of European unity: ‘When Europe is not divided, when we stand together and when we are clear and strong also in our willingness to stand up for ourselves, then the results will show.’
Trump responded to the resistance with economic threats, proposing a 10% import tariff on goods from eight European nations—Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands and Finland—with potential escalation to 25% if no Greenland purchase agreement materialized by June 1.
Political analysts observe that European leaders have undergone a significant learning curve in dealing with Trump’s transactional approach to international relations. Mark Shanahan, University of Surrey associate professor of political engagement, noted: ‘In Trump’s first term, Europe didn’t know what to expect and tried to deal with him using the old rules of diplomacy… It’s very hard for other leaders who deal with each other through the niceties of a rules-based system.’
Despite initially standing firm, Trump eventually backtracked on his most aggressive demands, canceling threats of using ‘force’ for Greenland’s acquisition and announcing a framework agreement that would make tariff threats unnecessary. However, European leaders maintained their position, with Frederiksen reiterating: ‘We cannot negotiate on our sovereignty.’
The confrontation signals a potential fundamental shift in transatlantic relations, with Canada’s Mark Carney suggesting that the alliance has experienced a ‘rupture’ rather than a transition, requiring European countries to build collective power against what he characterized as ‘bully’ behavior.
