Conservative radio host Erick Erickson did not mince words while blasting President Donald Trump’s demands to acquire Greenland.
Trump embarked on an overnight social media spree early Tuesday, sharing private messages from French President Emmanuel Macron, posting a fake image of U.S. control over the Arctic territory and claiming that there was “no going back” on his desire to seize the semi-autonomous island, which falls under the boundaries of Denmark, a NATO ally.
However, the president did signal some signs of diplomacy, going on to say at one point that he will meet with “various parties” about Greenland on the sidelines of the World Economic Forum this week in Davos, Switzerland.
Trump’s hope to acquire the territory — renewed after the successful U.S. military operation in Venezuela — has been met with fierce resistance from local officials and world leaders, with some NATO countries deploying troops to Greenland in defiance of the president’s threats. Trump has insisted that ownership is necessary for national security.
Erickson, a former Republican lawmaker who has supported Trump during both of his presidential campaigns, is now joining the opposition efforts. In a post on Substack titled “Insane Impulse Control Issues,” he blasted what he characterized as “some level of insanity” from the president over Greenland on Tuesday, arguing that he “simply has no impulse control.”
“There is no Trump Derangement Syndrome here except from his most ardent supporters who feel compelled to justify, explain, and defend every single thing Trump does, no matter how crazy,” Erickson wrote.
Erickson pointed to how Trump linked his stance on annexing Greenland to how he did not receive the 2025 Nobel Peace Prize in a letter sent to Norwegian Prime Minister Jonas Gahr Støre on Sunday.
According to several outlets, the letter stated, in part: “Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace, although it will always be predominant, but can now think about what is good and proper for the United States of America.”
Erickson called the messaging “nuts,” adding that “It’s Donald Trump at his worst.”
“It is belittling jacka--ery to a friend and ally,” he said. “It is unbecoming of the President of the United States. But some will undoubtedly defend it, dismiss it, or try to excuse it all away.”
Erickson did acknowledge, however, that he agreed with Trump about the “strategic importance” of Greenland, which the president has maintained that the United States must own to deter Russia or China from occupying it in the future.
“But this is counterproductive to accomplishing the security goal he wants,” Erickson wrote. “The Europeans cannot now be seen to be bullied into giving up 840,000 square miles of territory to an unhinged and obsessive eighty-year-old.”
He then delivered a blunt warning to the White House and the GOP, arguing that Trump’s behavior is “beneath the dignity of the Presidency and is shameful.”
“Trump’s obsession with Greenland risks driving the Europeans away from the United States and perhaps even into the arms of China, as Canada and Mexico are moving,” Erickson said. “That would break up NATO, have Europeans demand we get our troops out of Europe, and isolate the United States from our allies and the world.”
A handful of world leaders have already taken aim at Trump’s warnings during the economic forum on Tuesday.
While Canadian Prime Minister Mark Carney said that his country “strongly opposes” U.S. tariffs over Greenland, Macron, without mentioning Trump by name, warned against a “shift towards a world without rules, where international law is trampled under foot and where the only law that seems to matter is that of the strongest.”
