German Chancellor Friedrich Merz has openly endorsed US President Donald Trump's strong criticism of Spain regarding its defense spending obligations to NATO. During a meeting at the White House, Merz highlighted that Spain is the only NATO ally failing to meet the alliance's recommended defense spending target of 5% of GDP. His comments come amidst escalating tensions between the US and Spain over military cooperation and funding for NATO, with concerns that the lack of compliance by Spain could undermine collective security efforts.

President Trump has taken a hard stance, threatening to cut off trade with Spain and labeling the country as a 'terrible' ally due to its reluctance to engage more financially in defense commitments. The Trump administration has expressed frustrations over Spain's previous refusal to allow US military bases for potential strikes, particularly regarding operations in Iran. The issue reflects broader concerns about NATO members not fulfilling their financial responsibilities, which many believe could weaken the alliance in times of geopolitical challenges.

In response, Spanish Prime Minister Pedro Sanchez has dismissed the 5% defense spending target as 'unreasonable,' indicating that Spain has other priorities to fund. The ongoing dialogue between Germany, the US, and Spain underscores the complexities of NATO dynamics, particularly as European nations balance national budgets against the backdrop of collective security pressure from the US, hinting at potential shifts in international relations within the alliance.
