Nato countries discussed deploying troops to Greenland in response to Donald Trump threatening to use the US military to seize the Danish island, Report informs via The Telegraph.

Germany was among dozens of European allies understood to have held informal talks over “what Nato troops would do” if the US president followed through on his threats, diplomatic sources told The Telegraph.

Questions were even raised over whether Article 5, the Western military alliance’s mutual defense clause, could be invoked in the event of an American invasion of a fellow Nato member state.

It came after Trump started his second term in the White House openly considering a forcible takeover of Greenland, an autonomous part of Denmark.
