While the Arctic is indeed rich in resources, those resources won't necessarily produce competition unless they are economically viable, politically contested, and legally ambiguous — conditions that do not generally apply to the Arctic Ocean.
For a large offshore oil rig, the time from discovery to first oil can be more than a decade. There are currently no public plans for offshore Arctic oil rigs. The conditions are far too harsh, the costs far too high, and there is no guarantee that petroleum demand will hold into the future. Even if there were, this would hardly be cause for great-power competition. Arctic maritime territorial disputes are largely procedural, unresolved primarily due to political disinterest rather than controversy. This is evident in the resolution of Russia and Norway’s Arctic maritime boundary in 2010 with a treaty dividing the Barent Sea. To the degree that offshore resource deposits will become available as Arctic ice retreats, they are more likely to be economically marginal and legally and politically manageable than cause for a geopolitical maelstrom.
Arctic and non-Arctic countries alike revel in demonstrating Arctic combat capabilities. An Arctic-capable fighting force is a cold weather fighting force. But demonstrating Arctic capabilities does not imply a looming Arctic conflict; it simply allows nations to showcase their potential. Arctic war planning does not inevitably follow from cold weather capability building and signalling. Notably, the United States has not treated Alaska, its more direct point of access to the Arctic, as a locus for sustained militarisation.
Any strategic objectives the United States might seek to advance through Greenland can be achieved within existing mechanisms. Over-the-horizon radar, intelligence collection, and access to Arctic operating areas are all attainable through NATO cooperation, without the political and strategic costs that would accompany unilateral action. Indeed, the United States does not currently operate any major naval bases in Alaska, which offers comparable geographic advantages and direct access to the Arctic via the Pacific and a controlling position of the North West Passage. Through NATO, allies with established Arctic capabilities already act as force multipliers in and around Greenland; this collective advantage would be weakened, not strengthened, by coercive efforts to alter Greenland's sovereignty.
Any marginal strategic gains from annexation would therefore be outweighed by the immense damage such a move would inflict on alliance cohesion, trust, and US credibility — costs that would reverberate far beyond the Arctic. The persistence of annexation rhetoric appears less grounded in strategic necessity than in transactional thinking, a view captured by President Trump’s 2019 characterisation of Greenland as “essentially… a large real estate deal”.
