Donald Trump will not be able to force Greenland to change ownership, a former top adviser to the US president has told the BBC. IBM's vice chairman Gary Cohn, who advised Trump on the economy in his first term, said "Greenland will stay Greenland" and linked the need for access to critical minerals to his former boss's plans for the territory.

"I no longer feel an obligation to think purely of Peace," the president wrote in an extraordinary message to the Norwegian prime minister.

The president said he no longer needs to think “purely of Peace” after not winning the Nobel Peace Prize in a letter to the Norwegian Prime Minister.

He said he no longer thought "purely of Peace" as the row over the island threatened to reignite a trade war with Europe.

Seth Meyers has credited President Donald Trump’s obsession with Greenland to a “desperate craving” for trophies in a scathing late-night monologue. “America’s been through a lot over the years, but the one thing we’ve mercifully never had to deal with was a president who had a boner for winning awards,” Meyers said.

Trump, who has called himself the "President of Peace" wrote saying he was no longer feeling an "obligation to think purely of Peace."

President Donald Trump threatens steep tariffs on European nations unless Denmark sells Greenland to the U.S., citing national defense and security.
