Belgium’s foreign ministry has internally characterized the United States under President Donald Trump as “no longer” a reliable ally, according to an internal strategy document dated late 2025. The document, produced by the ministry’s Americas and Caribbean unit, urges Belgian officials to recalibrate their engagement with Washington while avoiding antagonism, and to strengthen ties with the Democratic opposition and emerging bipartisan figures.

The strategy calls for a comprehensive reassessment of Belgium’s and the European Union’s relationship with the US amid what it describes as shifting dynamics in America that threaten several vital Belgian and EU interests. Key concerns highlighted include US-instigated trade tensions with the EU, threats by President Trump to invade parts of European territory, and his support for far-right parties coupled with warnings about Europe’s “civilisational erasure.” These developments have contributed to a widening rift in transatlantic relations, prompting unease within European governments.

While the document emphasizes that engagement with the current US administration remains indispensable, it recommends significantly reinforcing dialogue beyond federal government levels, including increased contacts with Congress and identification of future American political leaders who could influence bilateral relations. The paper also notes that President Trump maintains respect for royal families, an observation followed by recent symbolic gestures, such as Belgium’s King Philippe attending the US-hosted football World Cup in July and Queen Mathilde joining Belgian ministers at the UN General Assembly in New York.

The Belgian foreign ministry spokesperson described the document as an internal working paper not reflective of a finalized policy, underscoring that the transatlantic relationship is evolving and requires careful management to safeguard national interests. The document identifies four principal areas for ongoing cooperation: economic relations, military spending, migration, and combating drug trafficking and organized crime. Among these, it suggests that joint efforts in fighting drug trafficking, organized crime, and terrorism present the most promising opportunities for collaboration.

European leaders have publicly reiterated the importance of their transatlantic alliance, given their reliance on the United States for security and trade partnerships. However, officials acknowledge behind closed doors that rising tensions have compelled a more cautious and diversified diplomatic approach.
