US senators have introduced bipartisan legislation aimed at safeguarding NATO unity amid rising tensions over Greenland. The bill would prevent US government funds from being used to seize, occupy or otherwise assert control over the territory of any NATO member state. This is a response to repeated statements by Donald Trump suggesting that Greenland, a self-governing territory of Denmark, should come under US control, even by force. Many believe that such rhetoric threatens NATO’s core principle of collective defence and undermines trust among allies. European leaders, particularly in Denmark and Greenland, have firmly rejected any suggestion of US control, emphasising their commitment to NATO, Danish sovereignty and the EU. On 16 January, with the territory’s strategic location and natural resources drawing global attention, Marco Rubio is due to meet the foreign ministers of Denmark and Greenland in Washington, and a bipartisan group of US lawmakers will be in Denmark for talks.
