President Trump used a NATO summit to renew calls for U.S. acquisition of Greenland and directly criticized Spain, according to Defense News. The remarks mark a sharp departure from traditional alliance diplomacy, with Trump framing Greenland as a strategic necessity while accusing Spain of inadequate defense spending.

The move signals a potential shift in U.S. force posture and Arctic strategy, as Greenland hosts a key U.S. air base and sits astride emerging shipping routes. Analysts suggest Trump's demand could test NATO cohesion by prioritizing bilateral land grabs over collective defense commitments.

Spain's response has been notably understated. The office of Prime Minister Pedro Sanchez said it was treating Trump's statements as "business as usual," adding that bilateral relations benefited both nations. Other NATO allies have remained publicly silent, though diplomatic sources indicate growing unease.

The financial implications of any Greenland acquisition remain unclear, as no formal offer or negotiation process has been disclosed. Trump's defense spending critique of Spain, however, aligns with long-standing U.S. pressure on NATO members to meet the 2% GDP target.

Critics argue the Greenland demand risks alienating Denmark, a key NATO member, and could distract from pressing alliance priorities such as Ukraine aid. The White House did not immediately clarify whether the comments were negotiating tactics or official policy.
