US President Donald Trump has ridiculed Denmark’s attempts to defend Greenland with additional patrols including two extra dog sleds as he insisted America would take control of the strategically crucial Arctic island.

President Trump told Denmark’s leader he wanted to take over Greenland, European officials say. Denmark has asked its E.U. allies not to inflame the situation until Mr. Trump’s intentions are clearer.

The Financial Times reports that Trump threatened Denmark's prime minister in a "horrendous" 45-minute phone call. From the reportage, you get the impression that Mette Frederiksen hadn't considered the possibility Trump was serious about Greenland and wasn't briefed on how to address the subject.
