US President Donald Trump and his officials are actively discussing a potential offer to buy the Danish territory of Greenland, the White House has confirmed.

It is something that's currently being actively discussed by the president and his national security team, White House spokeswoman Karoline Leavitt told reporters on Wednesday.

Both Greenland and Denmark have repeatedly stressed the island was not for sale.

Asked why the Trump administration had previously said it was not ruling out using military force to acquire Greenland, Leavitt replied that all options were always on the table but Trump's first option always has been diplomacy.

Concerns over the future of the territory resurfaced after Trump's unilateral use of military force against Venezuela on Saturday to seize its President Nicolás Maduro. Denmark, a fellow NATO ally, says an attack on its territory would end the military alliance.

The Trump administration claims Greenland is vital to US security due to its strategic location between North America and the Arctic, beneficial for monitoring missile threats and sea traffic.

Beyond security, there is rising interest in Greenland's natural resources like rare earth minerals, uranium, and potential oil reserves becoming more accessible as climate change melts its ice.

US Secretary of State Marco Rubio is set to have talks with Denmark next week.

Historically, Trump expressed interest in purchasing Greenland back in 2019, a move met with dismissal by Danish leadership.

The acquisition of Greenland by the United States is not a new idea, Leavitt emphasized.

She reiterated that Trump believes it serves US interests in deterring Russian and Chinese influence in the Arctic.

On a diplomatic front, European leaders rallied behind Denmark, stating that Greenland belongs to its people, and only Denmark and Greenland can decide on matters concerning their relations.

French Foreign Minister Jean-Noël Barrot conveyed that Rubio had ruled out the possibility of an invasion in recent discussions.

Aaja Chemnitz, a Greenland MP, criticized US assertions regarding any potential acquisition as disrespectful, while residents voiced their indifference to the potential transition from Danish to American oversight.
