Trump renews push for Greenland, claims massive oil, gas and mineral exploration is imminent

US President Donald Trump has renewed his campaign to highlight Greenland's strategic and economic importance, claiming that extensive oil, gas and mineral exploration is poised to begin on the Arctic island. In a post on Truth Social on Tuesday, Trump described Greenland's natural resources as vast and its geographical position as critical to the defence of the United States and Europe.

“Massive Oil, Gas, and Mineral Exploration is getting ready to begin in our new and beautiful Greenland!” Trump wrote, asserting that the territory possesses substantial, easily accessible oil reserves and offers unmatched military advantages.

His latest remarks bring renewed attention to Washington's longstanding interest in Greenland, an autonomous territory within the Kingdom of Denmark, and the debate over its natural resources, environmental policies and role in Arctic security.

Greenland's strategic value in Arctic defence

Trump's latest comments revive an issue that has shaped his approach to the Arctic since his first presidency. In 2019, he floated the idea of purchasing Greenland from Denmark, but the proposal was swiftly rejected by Danish and Greenlandic leaders.

Since returning to the White House, Trump has repeatedly argued that Greenland is essential to US national security because of its position between North America and Europe. In his latest post, he said the island offered unmatched “time, location, and sightline” for identifying and intercepting potential threats before they could reach the US mainland.

“Any future attack on the United States will have to come across Greenland,” Trump wrote, claiming American defences would be able to intercept drones, missiles and other weapons from the strategically positioned territory. He also described Greenland's importance to the defence of North America and Europe as “second to none”.

Greenland already hosts the US military's Pituffik Space Base, formerly known as Thule Air Base. The installation plays a key role in missile warning, space surveillance and Arctic operations and is considered a cornerstone of America's northern defence network.

Trump's renewed emphasis on the island's military value follows his repeated efforts to bring the territory under American control, which have strained relations with Denmark and Greenland. The United States already maintains a military presence there under existing agreements with Denmark, but Trump's broader ambitions have fuelled debate over sovereignty and Arctic security.

Oil and mineral ambitions face practical and environmental hurdles

Greenland is believed to contain substantial deposits of rare earth elements, zinc, iron ore, graphite and other minerals considered important for advanced manufacturing and clean-energy technologies. These resources have attracted interest from governments and private companies seeking to diversify supplies and reduce dependence on China, which dominates much of the global rare earth supply chain.

However, the prospects for large-scale extraction remain uncertain. Much of Greenland's mineral wealth lies in remote areas with limited infrastructure and challenging Arctic conditions. Harsh weather, difficult geology and high operating costs can make exploration and extraction expensive, despite the potential value of the deposits.

There is also a significant regulatory obstacle to Trump's oil and gas ambitions. Greenland decided in 2021 to stop issuing new oil and gas exploration licences, citing environmental and climate concerns as well as limited commercial prospects. Existing licences, however, remain valid under the applicable rules.

Trump has not provided details of the proposed exploration, including the companies involved, the locations concerned, the timeline or the regulatory approvals required. His announcement therefore does not establish that large-scale drilling or mining operations have received the necessary authorisations or are ready to begin.

Greenland remains a self-governing territory within the Kingdom of Denmark, with authority over its natural resources. Any major expansion of exploration would need to account for its regulatory framework and environmental requirements.

Trump's latest statement underscores the growing overlap between resource competition and military strategy in the Arctic. While he has presented Greenland as both an economic opportunity and a vital defensive outpost, the scale and feasibility of the proposed exploration remain unclear.
