Prime Minister Keir Starmer confronted Donald Trump over the weekend about plans to impose tariffs on European NATO members, declaring such actions inappropriate in the context of alliance security cooperation. The British leader’s forceful stance came during intensive diplomatic consultations aimed at presenting unified European opposition to American pressure over Greenland.
Trump’s controversial proposal targets eight European countries, including the United Kingdom, with sanctions related to their military presence in Greenland amid US territorial ambitions. Starmer conducted multiple high-level calls on Sunday, engaging with Danish leadership, European Union officials, and NATO command to coordinate a collective response to the unprecedented situation.
According to official summaries, Starmer consistently emphasized across all conversations that northern regional security serves all NATO allies’ interests in maintaining Euro-Atlantic stability. His position that punishing military partners economically for pursuing shared defense objectives violates basic alliance principles represents a direct repudiation of Trump’s transactional approach to security relationships.
The eight European nations facing tariff threats issued a joint declaration warning that Trump’s actions undermine the foundation of transatlantic partnership and risk triggering escalating tensions. Under the proposed schedule, 10% tariffs would take effect on February 1st, potentially rising to 25% by June 1st absent a deal meeting American demands regarding Greenland.
Starmer’s planned Monday press conference will articulate British concerns about the tariff threat without announcing reciprocal economic measures. Government strategists believe the Prime Minister’s surprisingly positive personal relationship with Trump, which has previously helped Britain navigate trade disputes favorably, might provide a pathway to de-escalating the current crisis through behind-the-scenes diplomacy.
