Keir Starmer confronted Donald Trump over plans to impose tariffs on NATO members as leverage for Greenland, declaring such economic pressure fundamentally inappropriate. The British Prime Minister’s weekend intervention came during intensive consultations with European officials aimed at presenting unified resistance to American territorial demands.
Trump’s controversial proposal targets eight European nations, including Britain, with sanctions related to their military deployment to Greenland in defense of Danish sovereignty. Starmer engaged in multiple Sunday calls with Danish leadership, EU officials, and NATO command to coordinate a collective European response to Washington’s aggressive stance.
Throughout his diplomatic outreach, Starmer emphasized that northern security cooperation serves shared NATO interests in protecting Euro-Atlantic stability. His position that punishing allies economically for defending collective security and territorial integrity violates basic alliance principles represents a direct challenge to Trump’s approach.
European countries facing tariff threats issued a joint declaration warning that Trump’s actions damage transatlantic partnership and risk triggering dangerous escalation. The tariff proposal involves 10% duties commencing February 1st, with potential increases to 25% by June 1st unless Denmark agrees to sell Greenland to satisfy American objectives.
Starmer plans to use Monday’s press conference to articulate British opposition clearly while avoiding announcements of reciprocal economic measures. Officials hope the Prime Minister’s surprisingly cordial personal relationship with Trump, which has previously yielded some trade advantages, might provide diplomatic space for resolving the crisis through private negotiations.
