WASHINGTON / OTTAWA — U.S. President Donald Trump has reiterated that the United States will “be there” for North Atlantic Treaty Organization (NATO), even as his administration’s statements on Greenland have unsettled allies and raised concerns across the transatlantic alliance.
In a public statement, President Trump emphasized that NATO’s strength depends heavily on U.S. participation, arguing that adversaries such as Russia and China would not fear the alliance without American leadership. He also renewed criticism of NATO members for what he described as historically insufficient defence spending, crediting U.S. pressure for recent increases by allied nations.
The remarks come amid renewed attention on Greenland, a self-governing territory of the Kingdom of Denmark, after the White House confirmed that a range of options for acquiring the Arctic territory are being discussed. While diplomacy was described as the preferred path, the administration did not rule out the potential use of military force, citing U.S. national security interests in the Arctic.
The comments have prompted strong reactions from NATO allies. Several European leaders, along with Canada, have publicly affirmed that Greenland’s future must be determined solely by the people of Greenland and Denmark, stressing respect for sovereignty and international law. The possibility of coercive action within NATO has been described by analysts as unprecedented and deeply destabilizing for the alliance.
Canada has taken a clear position in support of Danish-Greenlandic sovereignty. Prime Minister Mark Carney stated that decisions regarding Greenland rest exclusively with Denmark and Greenland, underscoring Canada’s commitment to NATO unity and Arctic stability. Canadian officials have also signalled an expanded diplomatic and security presence in the Arctic region.
Foreign policy experts warn that any unilateral action against a NATO member’s territory would fundamentally undermine the alliance, whose core principle is collective defence. They argue that maintaining alliance cohesion is critical at a time of heightened global instability and growing competition in the Arctic.
Despite the controversy, U.S. officials maintain that President Trump’s longstanding preference is to pursue any Greenland-related objectives through negotiation and deal-making rather than force. Talks with Danish leaders are expected to continue in the coming weeks.
As discussions unfold, NATO partners are watching closely, viewing the situation as a critical test of alliance solidarity, respect for sovereignty, and the future balance of power in the Arctic region.
