Greenland and NATO: A Student's Guide to Strategic Territories and Congressional Oversight

Hook: Students and teachers often need one reliable, classroom-ready place to understand why a remote island like Greenland suddenly dominates headlines and what Congress can do about it. This guide explains, in plain language and with classroom tools, why Greenland matters to the U.S. and NATO in 2026, how congressional oversight works, and how to turn the issue into a rigorous debate or research project.

Executive summary — most important takeaways first

• Strategic location: Greenland sits astride North Atlantic and Arctic approaches that matter for early warning, missile trajectories, and maritime routes.
• Legal status: Greenland is an autonomous country within the Kingdom of Denmark; Denmark controls defense and foreign policy but Greenland exercises growing self-rule (Home Rule 1979; Self-Government Act 2009).
• Congressional power: Congress shapes U.S. policy through funding, hearings, legislation, treaty advice and consent, and oversight tools like subpoenas and reporting requirements.
• 2026 context: Public statements by U.S. officials in late 2025–early 2026 increased attention and prompted intensified oversight and public debate; meanwhile NATO, Russia, and China continue expanding Arctic activity.
• Classroom utility: Greenland offers a compact case study that links geography, international law, Congress’s constitutional powers, alliance politics, and climate-driven change.

Why Greenland matters to U.S. and NATO policy in 2026

Greenland’s importance is practical, not symbolic. In 2026, four strategic trends make Greenland central to policymakers:

1. Geography and military value

Greenland is the world’s largest island and sits between North America, Europe, and the Arctic Ocean. Key military and intelligence assets — most notably U.S. facilities at Pituffik/Thule — provide early warning and space- and missile-tracking capabilities critical to NATO deterrence and U.S. homeland defense. Control of basing and access affects how quickly NATO forces can deploy into the Arctic and North Atlantic.

2. New sea routes and climate change

Arctic warming is opening longer windows for navigation through northern sea routes. Shorter shipping lanes between Europe and Asia change economic calculations and raise the prospect of contested maritime jurisdiction and search-and-rescue responsibilities. Greenland’s coastal position makes it a staging area for both commercial and military activity.

3. Natural resources and economic interest

Melting ice increases access to mineral deposits, rare earth elements, and hydrocarbons. While exploitation is technically and environmentally challenging, the potential value attracts state and commercial interest, which in turn fuels geopolitical competition.

4. Great-power competition

Russia has significantly increased its Arctic military posture, and non-Arctic powers (notably China) have declared strategic interests in polar regions. NATO has responded by moving the Arctic into alliance security planning. Greenland sits at the intersection of these rivalries: it is geographically essential and politically sensitive because it is part of the Kingdom of Denmark but home to an increasingly assertive Greenlandic government.

Legal and political status: who decides?

Understanding Greenland’s legal status is essential for any analysis of U.S. or NATO options.

• Autonomous within the Kingdom of Denmark: Greenland has internal self-government under the 2009 Self-Government Act; Denmark retains responsibility for defense and foreign affairs.
• Greenlandic agency: Greenlandic political leaders exercise growing influence on resource policy and international engagement. Any change in sovereignty or defense posture involves Danish, Greenlandic, and — under some circumstances — NATO consultation.
• Alliances and basing: U.S. basing or NATO operations in Greenland have generally been managed through agreements with Denmark, often coordinated with Greenlandic authorities for local matters (civil support, environmental protections, employment).

Congressional oversight: how the U.S. legislature shapes policy

Congress has multiple tools and constitutional authorities that shape how the United States approaches Greenland and NATO matters. For students, mastering these tools is essential to understanding checks and balances in foreign and defense policy.

Core constitutional and statutory powers

• Power of the purse: Congress funds (or restricts) military activities, basing, and aid through appropriations and the National Defense Authorization Act (NDAA).
• Declare war/authorize force: Article I gives Congress authority to declare war; the War Powers Resolution (1973) is a statutory mechanism for oversight of armed deployments.
• Treaty advice and consent: The Senate approves treaties and can influence binding international commitments.
• Oversight and investigations: Committees hold hearings, issue subpoenas, and require reporting from the executive branch.

Key congressional committees to follow

• Senate: Foreign Relations; Armed Services; Appropriations; Homeland Security and Governmental Affairs.
• House: Foreign Affairs; Armed Services; Appropriations; Oversight and Accountability.

Concrete oversight tools and how they work

Teachers and students can watch for these routine and potent actions:

• Hearings: Committees summon Cabinet officials, military leaders, and experts to testify. Hearing transcripts and video are public and make excellent primary sources for class assignments (see Congress.gov).
• Appropriations language and riders: Congress can include restrictions or reporting requirements in funding bills tied to activities in Greenland or the Arctic.
• Resolutions and non-binding measures: Simple resolutions (H.Res., S.Res.) signal congressional priorities and can pressure administrations even without legal force.
• Subpoenas and investigations: Where necessary, committees can subpoena documents and witnesses to inform legislative or oversight action.

Limits of congressional control

Congress’s power is significant but not absolute. Treaty negotiation and immediate operational control of military forces are normally managed by the executive branch. Congress influences policy through budgets, legislation, and public oversight rather than micromanaging on-the-ground deployments unless it chooses to act decisively through budget cuts or authorizations.

2026 trends and developments you should watch

Recent developments in late 2025 and early 2026 reflect several ongoing trends:

• Heightened public rhetoric: Statements by senior U.S. officials in late 2025–early 2026 raised tensions about possible uses of military force and control of strategic territories, driving congressional hearings and allied diplomatic responses.
• Stronger congressional scrutiny: Lawmakers from both parties increased oversight activity on Arctic policy, tying funding decisions to clearer reporting requirements and strategic reviews.
• NATO adaptation: NATO has continued integrating Arctic considerations into planning and exercises, coordinating more closely with Nordic allies and Denmark.
• Greenlandic agency: Greenlandic leaders pushed for greater say in resource and security decisions; classrooms should examine how local political movements affect international options.

Classroom debate framework — turn the policy issue into active learning

Greenland is ideal for role-play, policy memos, and mock hearings. Below are structured activities you can run in 60–120 minute sessions or as longer projects.

Debate topic suggestions

1. Resolved: The United States should prioritize bilateral basing agreements with Denmark over NATO-led solutions for Arctic defense.
2. Resolved: Congressional funding should include strict environmental and human-rights conditions on any Arctic military expansion.
3. Resolved: Greenlandic self-determination should take precedence over alliance strategic calculations.

90-minute mock congressional hearing (step-by-step)

1. Preparation (15 minutes): Assign roles — Majority/Minority committee chairs, Secretary of Defense, NATO representative, Greenlandic minister, Denmark ambassador, expert witnesses, media.
2. Opening statements (10 minutes): Chairs set the inquiry. Witnesses give two-minute opening remarks.
3. Questioning (45 minutes): Members ask witnesses. Encourage evidence-based questions — cite hearings, DoD or NATO statements, and local laws.
4. Deliberation and vote (10 minutes): Committee considers a non-binding report or recommendation.
5. Debrief (10 minutes): Discuss what changed, how oversight works, and real-world implications.

Research assignments and rubrics

Ask students to write a 1–2 page policy memo advising a member of Congress. Grading rubric should reward:

• Clear statement of the question and recommended action
• Use of primary sources (committee transcripts, DoD/NATO policy, Danish/Greenlandic government statements)
• Cost, legal, and diplomatic implications
• Concise, persuasive writing with cited sources

Primary sources and research tools — where to look

Trustworthy official sources make the best foundation for research and classroom materials. Start with these:

• Congress.gov: Bill text, hearing schedules, committee reports.
• GovInfo.gov: Government publications, committee prints, and federal registers.
• U.S. Department of Defense and Department of State: Official strategy documents and press statements on Arctic policy.
• NATO.int: Alliance statements, communiqués, and initiatives relating to the Arctic and northern flank.
• Danish Ministry of Foreign Affairs and Government of Greenland (Naalakkersuisut): Statements on sovereignty, defense, and resource policy.
• Congressional Research Service (CRS) reports: Detailed, nonpartisan backgrounders available through congressional offices or public repositories.

Practical, actionable steps for students and teachers

Turn interest into credible research and civic engagement with these steps:

1. Set alerts: On Congress.gov and major committee pages for hearings and bills about the Arctic, Greenland, or basing agreements.
2. Collect primary materials: Download hearing transcripts, DoD Arctic strategy documents, and NATO statements. Save statements from the Danish and Greenlandic governments for local perspective.
3. Request documents: Use FOIA.gov to submit Freedom of Information Act requests for U.S. government records; consult your university or public library for help with CRS reports.
4. Contact experts: Invite a congressional staffer, regional specialist, or defense analyst for a Q&A. Prepare focused questions in advance.
5. Create a policy memo: Require students to recommend a specific congressional action (e.g., a reporting requirement in the NDAA) and justify it with cost, legal, and diplomatic analysis.

Case studies: lessons from history and recent practice

Case studies help students link abstract powers with concrete outcomes.

1. Thule Air Base

The U.S. base in northern Greenland is a practical example of how basing, host-nation agreements, and local rights interact. Students should examine the history of U.S.-Danish arrangements and the local impacts on Greenlandic communities.

2. 2019 purchase talk and 2025–2026 rhetoric

In 2019, public discussion about buying Greenland made clear how geopolitical rhetoric can strain alliances. Similar rhetoric surfaced again in late 2025–early 2026, prompting congressional letters and hearings (see committee schedules on Congress.gov). These episodes are useful to study how domestic political statements ripple into international relations and oversight.

Future predictions — what classrooms should track through 2026 and beyond

Based on current trajectories, students should prepare for these likely developments:

• Increasing congressional activity: Expect more hearings, NDAA language, and appropriations conditions tied to Arctic posture and environmental protections.
• Deeper NATO-Arctic cooperation: The alliance is likely to formalize more coordination with Nordic members on exercises, intelligence-sharing, and search-and-rescue capabilities.
• Greenlandic political evolution: Greenland’s domestic politics will increasingly shape the strategic calculus — especially around resource development and local consent for foreign basing or major infrastructure projects.
• Environmental constraints: Climate impacts will make any basing or resource extraction politically and technically more complex, increasing the need for environmental reviews and community engagement.

Teaching note: Treat Greenland as a living case study where geography, law, and democratic oversight intersect. Emphasize evidence, constitutional processes, and the voices of local Greenlandic actors.

Wrap-up: what students and teachers should do next

Greenland is more than a map dot; it is a strategic territory with real diplomatic, military, and environmental implications. For teachers: build one or two activities from this guide into your curriculum this semester. For students: practice drafting a short congressional memo and follow a committee hearing from start to finish. For both: use authoritative sources, prioritize primary documents, and center Greenlandic perspectives in your analysis.

Call to action

Turn interest into impact: run a mock congressional hearing in class, subscribe to official committee feeds on Congress.gov, and assemble a short policy memo for a local representative that summarizes what you learned and asks for greater transparency on Arctic policy.
