An opinion poll indicated that 85% of Greenlanders do not wish their Arctic island - a semi-autonomous Danish territory - to become a part of the United States, with nearly half saying they see interest by U.S. President Donald Trump as a threat. Trump said earlier this month that Greenland was vital to U.S. security and Denmark should give up control of the strategically important island. The survey by pollster Verian, commissioned by the Danish newspaper Berlingske and Greenlandic daily Sermitsiaq, showed only 6% of Greenlanders are in favour of their island becoming part of the U.S., with 9% undecided.
