President Donald Trump has again insisted that the US "needed" Greenland for security reasons and has refused to rule out the use of force to take control of the semi-autonomous Danish territory.
At a meeting in Paris today, European leaders rallied to Greenland's defence - issuing a joint statement saying Greenland belongs to its people, and that they will defend Greenland's territorial integrity.
The BBC's James Waterhouse has been following the story from Paris.
To hell with Trump! To hell with Trump’s henchmen and henchwomen! And to hell with America! Greenland belongs to the Greenlanders. Only the Greenlanders and the Danes can determine its future.
The sooner that we Europeans unite and build an extremely strong military to be able to defend ourselves, the better. America is no longer our ally. Only a fool would consider America as an ally now. — © Mark Alexander
