The Danish government has admitted that initially it did not take Trump seriously, but now they believe its possible that Trump could orchestrate a military invasion of Greenland. As we read in the Kiev Independent:

U.S. President Donald Trump aggressively defended his plans to take over Greenland in a phone call with Danish Prime Minister Mette Frederiksen, the Financial Times (FT) reported on Jan. 24.

In the weeks leading up to his inauguration, Trump publicly floated the idea of a U.S. takeover of Greenland, Canada, and the Panama Canal. In comments to reporters on Jan. 7, he refused to rule out the possibility of using military force to seize Greenland, which he said the U.S. needs for “economic security.”

In a 45-minute call that took place a few days before Trump’s inauguration, Trump grew increasingly aggressive and confrontational when Frederiksen said Greenland was not for sale, senior European officials told FT.

“It was a cold shower,” one official said. “Before, it was hard to take it seriously. But I do think it is serious, and potentially very dangerous.”

Another official described the conversation as “horrendous.”

…

Frederiksen reportedly told Trump that Denmark was willing to deepen cooperation with the U.S. on military bases and mineral extraction, but these offers did not appease him.

“The intent was very clear. They want it. The Danes are now in crisis mode,” one official said.
