Trump has escalated from inflammatory rhetoric to explicit threats against a NATO ally and its autonomous territory, Greenland. These threats now include economic coercion, alliance pressure, and refusal to rule out the use of force. Congress must intervene immediately. Denmark has begun reinforcing its military presence in Greenland in response to U.S. threats—an extraordinary and alarming development between allies. Allowing a president to threaten a NATO ally with force or economic punishment based on personal grievance places the United States on a path toward isolation, instability, and long-term loss of credibility. I encourage Congress to act immediately by: 1. Publicly repudiating any attempt to seize or coerce control over Greenland. 2. Passing legislation or a War Powers resolution prohibiting the use of U.S. forces against Denmark or Greenland without explicit congressional authorization. 3. Blocking funding for any military, intelligence, or economic action intended to pressure Denmark or Greenland. 4. Holding immediate oversight hearings on the President’s conduct, decision-making, and fitness with respect to foreign policy and national security. 5. Reaffirming U.S. commitments to NATO and the post–World War II rules-based international order. Silence now is acquiescence. Congress is the last Constitutional guardrail. It must act. YOU must act.
