US Vice President JD Vance said European leaders should “take the President of the United States seriously” when asked about Washington’s stance on Greenland. Vance said Greenland is critical for missile defense and warned that if Europe fails to address security concerns, the US may act, without specifying how. He added that diplomatic talks with Denmark and Greenland are expected soon. European leaders, including Denmark and Greenland’s prime minister, have rejected any US move to annex the island.
