Pathway A: Expand Basing Moderate Viability

Conditions Status
TL;DR The Bottom Line

Expanded basing is the only legally straightforward path. It builds on the existing 1951 Defense Agreement and requires the fewest consents. Purchase/cession and independence-first are theoretically possible but require a cascade of approvals that current political realities make implausible. Coercion is not a "pathway" at all - it's a violation that produces illegitimate outcomes. Any serious strategy focuses on Lane A.

A

Expand Basing and Defense Cooperation

Legally Straightforward

Current Status: Pituffik Space Base

The US already has a significant presence in Greenland. Pituffik Space Base (formerly Thule Air Base) is the US military's northernmost installation, located 750 miles north of the Arctic Circle. It hosts the 821st Space Base Group and operates critical early-warning radar systems for missile defense and space surveillance.

  • Established 1951 under the bilateral US-Denmark defense agreement
  • Primary mission: ballistic missile early warning and space surveillance
  • Hosts Space Force's 12th Space Warning Squadron
  • Deep-water port at Thule enables year-round resupply
  • Approximately 600 personnel (mix of military, civilian, contractors)

The 1951 Defense Agreement Structure

The current US presence operates under the 1951 "Agreement Between the United States and Denmark Concerning the Defense of Greenland." This treaty was negotiated during the early Cold War when Denmark joined NATO.

  • Bilateral treaty between US and Denmark (Greenland had minimal autonomy in 1951)
  • Defense areas designated where US can operate without Danish permission for each action
  • Cost-sharing arrangements for infrastructure and operations
  • Status of Forces provisions covering jurisdiction over US personnel
  • Amendment process allows expansion through diplomatic negotiation

What Expansion Would Require

Expanding US presence beyond Pituffik - additional bases, new capabilities, or broader operational authority - requires amending the 1951 agreement or negotiating supplementary arrangements.

  • New defense areas for additional installations
  • Enhanced access rights for air, sea, and potentially submarine operations
  • Updated cost-sharing for new infrastructure investment
  • Technology agreements for advanced radar, communications, or missile defense
  • Environmental protocols (increasingly important given Arctic sensitivity)

Step-by-Step Process

  • 1 US initiates diplomatic discussions with Danish Ministry of Foreign Affairs
  • 2 Denmark consults with Greenland Self-Government (required under 2009 Act for foreign policy affecting Greenland)
  • 3 Technical negotiations on scope, locations, capabilities, and costs
  • 4 Draft agreement circulated for review by both governments
  • 5 Danish Parliament (Folketing) approval if treaty amendment required
  • 6 US executive agreement (if within presidential authority) or Senate ratification (if treaty-level)
  • 7 US House appropriations for any new spending
  • 8 Implementation and construction

What Could Break It

  • Danish domestic politics: Coalition government collapse or election that brings anti-expansion parties to power
  • Greenlandic opposition: Strong public resistance forces Denmark to decline (political reality even if not legal veto)
  • US coercion backfire: Threatening rhetoric hardens positions and makes cooperation impossible
  • Environmental concerns: Climate activists or indigenous rights groups create significant obstacles
  • Russian/Chinese countermoves: Geopolitical complications that change Denmark's calculus
B

Purchase or Cession Treaty

Legally Contestable

Historical Precedent

The US has acquired territory through purchase before. These precedents are often cited but occurred in fundamentally different legal and political contexts.

  • Louisiana Purchase (1803): $15 million from France. No indigenous consultation. Pre-dates modern self-determination law.
  • Alaska Purchase (1867): $7.2 million from Russia. Indigenous Alaskans not consulted. Russia's claim was itself disputed.
  • US Virgin Islands (1917): $25 million from Denmark. No plebiscite in the islands. WWI urgency.
  • Proposed Greenland purchases (1867, 1946): Both rejected by Denmark.

Why the 21st Century Is Different

Modern international law has evolved dramatically since the Alaska purchase. Key developments make a simple purchase transaction legally and politically implausible.

  • UN Charter (1945): Established self-determination as a fundamental principle
  • Decolonization era (1960s-70s): UN Resolution 1514 declared colonial peoples have right to determine their status
  • Greenland Self-Government Act (2009): Denmark explicitly recognized Greenland's right to independence
  • Indigenous rights frameworks: UN Declaration on Rights of Indigenous Peoples (2007)
  • Greenlandic identity: 56,000 people with distinct culture, language, and political institutions

Modern Self-Determination Requirements

Any transfer of sovereignty over a populated territory in the modern era requires the consent of the population. This is not merely a policy preference - it is a jus cogens norm (peremptory rule) of international law.

  • Referendum required: Greenlandic voters must approve any change in status
  • Free and fair process: No coercion, adequate information, genuine choice
  • International observation: Likely UN or OSCE monitoring to ensure legitimacy
  • Transition negotiations: Terms must protect minority rights, property, citizenship

Treaty Process Walkthrough

  • 1 Greenland Self-Government initiates process (or responds to external proposal)
  • 2 Greenlandic referendum on principle of transferring sovereignty to US
  • 3 If approved, Greenland Parliament authorizes negotiations
  • 4 Denmark-Greenland joint position developed for negotiations with US
  • 5 Trilateral negotiations on terms: governance, citizenship, financial arrangements, military
  • 6 Draft treaty finalized
  • 7 Second Greenland referendum on specific treaty terms
  • 8 Danish Parliament (Folketing) approval to cede territory
  • 9 US Senate ratification (2/3 majority required)
  • 10 US House passes implementing legislation and appropriations
  • 11 Formal transfer ceremony and implementation

What Could Break It

  • Greenland votes no: Polls consistently show majority oppose US acquisition
  • Denmark refuses to negotiate: Current and foreseeable governments categorically oppose
  • US Senate fails 2/3 threshold: 67 votes is a high bar for controversial treaty
  • International backlash: EU and NATO allies pressure Denmark to refuse
  • Price too high: Greenland might demand compensation Denmark/US unwilling to pay
  • Process takes too long: Political conditions change during multi-year negotiation
C

Independence First, Then Association

Legally Contestable

Self-Government Act 2009: The Independence Provision

Denmark's Self-Government Act explicitly provides a pathway for Greenland to become independent. This is not a theoretical possibility - it's a statutory right.

  • Section 21: "Decision regarding Greenland's independence shall be taken by the people of Greenland"
  • Binding referendum: If Greenlanders vote for independence, Denmark must negotiate separation
  • Financial implications: Independence would end Danish block grant (approximately 3.5 billion DKK annually)
  • No Danish veto: Denmark cannot refuse if Greenlanders vote for independence

The Marshall Islands / Palau Model

The US has existing relationships with former trust territories that achieved independence but maintain close ties through "Compacts of Free Association." This model could apply to an independent Greenland.

  • Republic of the Marshall Islands: Independent since 1986, Compact provides defense, funding, visa-free travel
  • Republic of Palau: Independent since 1994, similar compact structure
  • Federated States of Micronesia: Third compact partner
  • Key features: US provides defense and funding; associate states control domestic policy; citizens can live/work in US

Free Association Options for Greenland

An independent Greenland could negotiate various levels of association with the United States, from defense partnership to full integration as a compact state.

  • Defense agreement: US provides security guarantee, maintains bases, Greenland remains fully sovereign
  • Compact of Free Association: More integrated - US controls defense and foreign policy in exchange for funding
  • Commonwealth status: Similar to Puerto Rico - US citizens, internal self-governance, but not statehood
  • Full statehood: Requires separate Congressional process after acquisition

Timeline and Steps

  • 1 Greenland Parliament (Inatsisartut) calls independence referendum
  • 2 Referendum passes (simple majority assumed)
  • 3 Denmark-Greenland negotiations on separation terms (2-5 years)
  • 4 Greenland establishes independent government structures
  • 5 International recognition (UN admission, bilateral relations)
  • 6 Independent Greenland opens negotiations with US on association
  • 7 Compact or treaty negotiated
  • 8 Greenland referendum on association terms
  • 9 US Congressional approval (treaty ratification or compact legislation)
  • 10 Implementation

Estimated timeline: 10-15 years minimum from initial referendum to association with US.

What Could Break It

  • Independence referendum fails: Greenlanders may prefer Danish connection over uncertainty
  • Economic viability concerns: Loss of Danish subsidy creates financial crisis
  • Independent Greenland chooses differently: May prefer EU association, Nordic partnership, or true neutrality
  • China or others offer better terms: Independent Greenland could shop for partners
  • US overreach during process: Heavy-handed approach alienates Greenlandic opinion
  • Domestic US opposition: Congress may not want to take on new territorial responsibilities
D

Coercion or Unilateral Action

Legally Toxic

Why It Fails Under International Law

Coercion is not a "pathway" - it is a violation. Any attempt to acquire Greenland through threats, force, or pressure that bypasses consent produces outcomes that are legally void and permanently illegitimate.

  • UN Charter Article 2(4): "All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state"
  • Jus cogens violation: The prohibition on aggressive force is a peremptory norm - no treaty or agreement can override it
  • Self-determination: Coerced populations do not lose their right to determine their status
  • No prescription: Unlike some legal violations, aggressive acquisition of territory cannot become legitimate through time

Vienna Convention on Coerced Treaties

Even if Denmark or Greenland signed documents under pressure, those documents would be legally void from the beginning.

  • Article 51: "The expression of a State's consent to be bound by a treaty which has been procured by the coercion of its representative through acts or threats directed against him shall be without any legal effect"
  • Article 52: "A treaty is void if its conclusion has been procured by the threat or use of force in violation of the principles of international law embodied in the Charter of the United Nations"
  • No ratification cure: Coerced treaties cannot be "cured" by subsequent parliamentary approval

Practical Enforcement Problems

Beyond legal invalidity, coerced acquisition creates permanent practical problems that undermine any benefit.

  • Perpetual resistance: Population that didn't consent continues to oppose
  • International isolation: Other states refuse to recognize acquisition
  • Economic sanctions: Trading partners may impose costs
  • Alliance collapse: NATO allies lose trust in US commitments
  • Domestic opposition: Many Americans would oppose holding unwilling territory
  • Resource curse: Local population can sabotage resource extraction

Why Any Outcome Is Illegitimate

The fundamental problem with coercion is not that it's difficult - it's that it cannot produce legitimate control even if "successful."

  • No stable title: Other states and future US administrations can challenge the acquisition
  • Moral stain: US would join Russia (Crimea), Iraq (Kuwait), and other aggressors
  • Precedent destruction: Undermines the rules-based order the US built and benefits from
  • Self-defeating: Arctic security is better served by willing allies than resentful subjects

Why This "Pathway" Cannot Succeed

  • NATO Article 5 paradox: Attacking Danish territory could theoretically trigger collective defense - against the US
  • Article 4 consultations: Denmark can invoke consultations when security threatened by an ally
  • EU solidarity: Greenland's association with EU means European involvement
  • UN Security Council: Allies could seek UNSC action (US could veto, but at massive diplomatic cost)
  • Congressional opposition: Many in Congress would refuse to appropriate funds for illegally-held territory
  • Judicial challenges: US courts could find executive action unconstitutional

Pathway Comparison

Factor
A: Expand Basing Straightforward
B: Purchase/Cession Contestable
C: Independence First Contestable
D: Coercion Toxic
Greenland referendum required? No Yes (2x) Yes (2x) Bypassed
Denmark must consent? Yes Yes To independence Bypassed
US Senate 2/3 required? Maybe Yes Likely Bypassed
US House appropriations? Yes Yes Yes Uncertain
Timeline 1-3 years 5-10 years 10-15 years N/A
Probability of success Moderate Very Low Low Zero (void)
UN Charter compliant? Yes Yes Yes No
NATO compatible? Yes Yes Uncertain No
Outcome if "successful" Expanded access Full sovereignty Association Illegitimate
Key Takeaways
  • Basing expansion is the only realistic near-term option - it builds on existing agreements and requires the fewest consent hurdles
  • Full acquisition requires Greenlandic consent - this is non-negotiable under modern international law
  • The 21st century is not 1867 - self-determination norms make simple purchase transactions impossible
  • Coercion is self-defeating - even if "successful," it produces illegitimate outcomes that cannot be stabilized
  • Any serious strategy focuses on winning hearts and minds - making the US an attractive partner, not a threatening presence
