Denmark deployed soldiers to both Iraq and Afghanistan when America launched the Global War on Terrorism. Fifty of their soldiers never came home. Now the United States refuses to rule out military action to seize Greenland from the NATO ally.

This agreement is very generous, it's very open,” one foreign policy expert said. “The U.S. would be able to achieve almost any security goal that you can imagine under that agreement.”

The rhetoric follows a dramatic U.S. raid in Venezuela and revives Trump’s long-standing focus on Greenland, transforming diplomatic discussions into fears of coercion. But U.S. military posture there remains unchanged.

Veteran diplomat tells CBS News Denmark "ready to cooperate" on Greenland, and he expects U.S. to abandon "anachronistic approach of colonialism" post-Trump.

Marco Rubio said he'd be meeting with Denmark after the White House said it was looking at options to acquire Greenland, including military action.

Denmark ‘s Ministry of Defense has announced that it will respond with military force if the US carries out an invasion of Greenland, vowing to “shoot first and ask questions later.”

Sadly, for us, based on key indicators of conventional military preparedness, the answer appears to be Denmark. Despite its small size and population (six million, as opposed to Canada’s 41 million), and generous social benefits, Denmark has more modern and technologically advanced ships, aircraft, tanks and air defence systems.

The leaders of Canada, France, Germany, Italy, Poland, Spain and the U.K. joined Denmark’s Prime Minister Mette Frederiksen on Tuesday in defending Greenland’s sovereignty in the wake of Trump’s comments about Greenland, which is part of the NATO military alliance.

As the US escalates talk about gaining control of Danish-controlled Greenland, a Cold War-era directive has drawn attention. It stipulates that Denmark's troops must immediately engage with foreign troops attacking Danish territory,
