U.S. President-elect Donald Trump refused on Tuesday to rule out using military or economic action to pursue acquisition of the Panama Canal and Greenland, part of a broader expansionist agenda he has promoted since winning the Nov. 5 election.

Trump, who takes office on Jan. 20, also floated the idea of turning Canada into a U.S. state, said he would demand far higher defense spending from NATO allies and promised to change the name of the Gulf of Mexico to the Gulf of America.

Still two weeks away from taking office, Trump has begun outlining an aggressive foreign policy with little regard to diplomatic considerations or the concerns of U.S. allies.

Asked at a press conference at his Florida resort whether he could assure the world he would not use military or economic coercion as he tries to gain control of the Panama Canal and Greenland, Trump said, “No, I can’t assure you on either of those two.

But I can say this, we need them for economic security.”

Trump criticized American spending on Canadian goods and military support for Canada, saying the U.S. derives no benefits from doing so, and called the border between the two countries an “artificially drawn line.”

He suggested he would impose tariffs on Denmark if it resists his offer to purchase Greenland, which he said is vital to U.S. national security. Shortly before Trump’s comments, his son Don Jr. arrived in Greenland for a private visit.

Denmark has said Greenland, a self-governing part of its kingdom, is not for sale.

“I don’t think it’s a good way forward to fight each other with financial means when we are close allies and partners,” Denmark’s Prime Minister Mette Frederiksen said late on Tuesday in response to Trump’s comments.

CANADA SAYS: ‘WE WILL NEVER BACK DOWN’

Canada’s minister of foreign affairs, Melanie Joly, said on X, “President-elect Trump’s comments show a complete lack of understanding of what makes Canada a strong country. Our economy is strong. Our people are strong. We will never back down in the face of threats.”

Panamanian authorities did not immediately comment. Panamanian President Jose Raul Mulino has previously rejected the notion of turning the canal back to the U.S., which had owned it before handing over control to Panama in 1999.

Ambassador Daniel Fried, a retired U.S. diplomat now with the Atlantic Council think tank, said Trump’s comments painted a picture of national power as territorial expansion and compared him to a “19th century imperialist.”

Seizing Greenland, Fried said, “would destroy NATO, because it would make us no different than Vladimir Putin,” Russia’s president.

Trump’s promise to rename the Gulf of Mexico echoed his previous vow to revert the name of Denali, the highest mountain peak in North America, to Mount McKinley.

Former President Barack Obama changed the name of the Alaskan mountain in deference to Native Americans.

Mexican Economy Minister Marcelo Ebrard, who is expected to play a key role in looming U.S.-Mexico trade issues, appeared to dismiss Trump’s call to rename the shared body of water later on Tuesday.

“Today I’d tell you if we saw each other in 30 years, the Gulf of Mexico will still be called the Gulf of Mexico,” he said, adding that the Mexican government would not get drawn into the debate.

Typically, the U.S. Board of Geographic Names sets geographic names, though presidents have also renamed geographic features via executive action.
