Denmark on Wednesday dismissed U.S. President Donald Trump's vow to take over Greenland "one way or the other" in a speech to Congress.

"That won't happen," Danish Defense Minister Trouls Lund Poulsen told public broadcaster DR, adding that "the direction that Greenland wants to take will be decided by Greenlanders". He noted that Trump had also expressed support for the people of the autonomous Danish island to determine their own future.
