Denmark sent private messages in recent days to President-elect Trump's team expressing willingness to discuss boosting security in Greenland or increasing the U.S. military presence on the island, two sources with knowledge of the issue tell Axios.

Copenhagen has been deliberating over how to respond to statements by US President-elect Donald Trump about his desire to annex Greenland, amid indications that these remarks are not merely jokes. Danish officials have reportedly received signals from Trump's advisors and allies suggesting that he is serious about his plans.

The president-elect’s latest proposal places politicians in Copenhagen and the Greenlandic capital of Nuuk in a great bind.
