President Trump announced a major deal with Denmark Friday evening over America’s role in Greenland. In a Truth Social post, the president wrote that the deal “gives the United States permanent control over security . . . in Greenland.” The president added that “no U.S. adversary can EVER . . . have a military presence in Greenland, or make sensitive investments in Greenland” without approval from the United States. This is an incredibly important deal because Communist China was moving aggressively to establish a foothold on the strategic island.
