Donald Trump said Friday his administration will take action on Greenland “whether they like it or not,” further escalating his rhetoric as he pushes to acquire the Danish territory for the U.S.

The comments came during a meeting with oil executives to discuss the prospect of doing business in Venezuela. Less than a week earlier, the U.S. military invaded the oil-rich South American nation and captured its leader, Nicolás Maduro.

Denmark and its European allies in NATO – the military alliance co-founded by the U.S. – have pushed back, reiterating that Greenland is not for sale. But the Trump administration nevertheless says it is currently weighing a range of options on Greenland, including utilizing the U.S. military or cutting a deal to purchase it from Denmark.
