Urgent Concern Regarding Reports of U.S. Military Planning Involving Greenland

I am writing as a deeply concerned constituent regarding recent reporting and statements surrounding the United States’ posture toward Greenland, an autonomous territory of the Kingdom of Denmark and a long-standing NATO ally. On multiple occasions, Senator Chuck Grassley and others have assured constituents that President Donald Trump would never invade Greenland and that such concerns were unfounded. However, recent reporting indicates that President Trump has asked for plans exploring the use of military force to seize or control Greenland. These reports have been serious enough to alarm U.S. allies and prompt defensive discussions within NATO. This contradiction between public assurances and reported actions is deeply troubling. Any suggestion of using military force against the territory of a NATO ally is reckless, destabilizing, and fundamentally incompatible with U.S. treaty obligations, constitutional norms, and international law. Greenland’s status is not a matter for unilateral U.S. action. Decisions about its future belong to the people of Greenland and Denmark—not the U.S. executive branch acting through coercion or military threat. Even entertaining invasion planning sends a dangerous signal to the world. It undermines NATO unity, emboldens authoritarian regimes, weakens American credibility, and risks unnecessary escalation in the Arctic at a time when cooperation—not confrontation—is essential for global stability. I urge you to take immediate action by: Publicly and unequivocally rejecting any use or threat of military force against Greenland or any NATO ally. Demanding transparency from the administration regarding any military planning or directives related to Greenland. Reasserting Congress’s sole constitutional authority to declare war and preventing executive overreach. Supporting diplomatic engagement and cooperation with Denmark, Greenland, and NATO partners rather than coercion. The American people deserve honesty from their leaders, and our allies deserve assurance that the United States will honor its commitments. Silence or ambiguity in the face of such reports risks normalizing behavior that would have been unthinkable under any previous administration. I expect my representative to act decisively to prevent an unnecessary and dangerous crisis and to uphold the Constitution, international law, and our alliance obligations. Thank you for your attention to this urgent matter.
