US President Donald Trump on Tuesday reiterated his claim that Greenland should be under US control, saying the island "should be controlled by the United States, not by Denmark." Speaking to reporters on the sidelines of the NATO summit, Trump argued that Greenland is strategically important to the United States. He said he does not intend to let Greenland be threatened by those countries. Greenland is a self-governing territory within the Kingdom of Denmark, a NATO ally. Trump has repeatedly expressed interest in bringing the island under US control, a proposal that has been rejected by Danish and Greenlandic leaders.
