Sri Lanka, April 9 -- US President Donald Trump bashed NATO and appeared to renew his threats over Greenland after a closed-door meeting with alliance chief Mark Rutte, during which he was expected to discuss possibly leaving the pivotal security bloc.

Trump's outrage at NATO allies over their failure to join in his war against Iran had prompted fears he would seek to pull the United States out of the nearly eight-decade-old alliance.

"REMEMBER GREENLAND, THAT BIG, POORLY RUN, PIECE OF ICE!!!" he added, without any further explanation....
