What Washington Can Already Do in Greenland Without Asking

Washington is celebrating a Greenland agreement that Copenhagen still describes as awaiting signature. President Donald Trump announced on September 18 that the United States had secured “permanent control over security” following months of threats over the island’s status. Denmark’s official announcement, updated September 20, says Greenland, Denmark and the United States are expected to sign during the United Nations General Assembly, with entry into force subject to necessary parliamentary procedures. That gap matters when the claim is authority to act without asking. (investing.com¹)

As of September 21, I could not locate a published signed instrument or operative annexes establishing the new permissions. The official announcement supplies neither those provisions nor a detailed implementation timetable. It establishes a prospective agreement, rather than proof that Washington has already acquired enforceable new powers. The immediate question is therefore narrower than Trump’s announcement suggests: which decisions would cease to require Danish or Greenlandic approval? (english.stm.dk²)

There is reason to take the possibility of a substantial change seriously. Reuters reported an unnamed State Department official’s description of permanent access, basing and overflight rights, restrictions on non-NATO bases and sensitive investments, and an agreement that would survive Greenlandic independence. PolitiFact also reported officials describing permanent rights to establish military bases. These are accounts of proposed commitments, however, not published clauses showing their boundaries. (internazionale.it³)

I would reject the claim that permanent American security control has been established. I would also reject the comforting assumption that preserving Danish sovereignty makes any expansion harmless. A government can retain its territory while signing away important future choices. The distinction to investigate is between consenting to an American presence now and retaining the power to refuse its expansion later.

The starting point is the 1951 Greenland Defense Agreement, the NATO-related framework for American military access. Article II already authorizes construction, equipment, personnel and internal security within agreed American-operated defense areas. It preserves Danish sovereignty, Danish authorities’ freedom of movement and cooperative Danish use. Crucially, selecting defense areas requires agreement between the two governments. Washington’s freedom inside an authorized area does not amount to freedom to choose any new location. (avalon.law.yale.edu⁵)

That geographic boundary survived the 2004 Igaliku amendment, signed with Greenlandic participation. Article 1 identifies Thule as the sole defense area and expressly preserves the 1951 procedure for establishing others. Article 3 requires Washington to consult and inform Denmark, including Greenland’s government, before significant changes to military operations or facilities. It does not expressly require a new approval vote for every such change. (govinfo.gov⁶)

This is where loose descriptions become misleading. Basing rights are permissions to station forces and operate facilities; their scope depends on the activities and territory authorized. A promise of additional buildings could describe work already permitted inside an existing area. Permission to designate additional territory unilaterally would be a much larger concession. I would need the site provisions and any maps before treating those two propositions as equivalent. The existing texts make that distinction consequential. (avalon.law.yale.edu⁵)

Movement rights are already extensive, too. Article V permits American aircraft to overfly and land throughout Greenland, except as mutually restricted. Movement between defense areas operates under mutually agreed rules. Specified surveys, including engineering surveys for selecting defense areas, require agreement with Danish authorities. The 2004 amendment adds consultation and information for exceptional planned military landings outside airports, protecting environmental and hunting interests. Thus, access across the island is broader than permission to establish installations across it. (avalon.law.yale.edu⁵)

The practical comparison must separate three things: (1) activities already authorized, (2) changes requiring advance consultation, and (3) new territory requiring agreement. Calling all three “control” conceals the decision that matters. Equally, saying Washington must always ask permission would invent a host-government veto that the consultation provisions do not expressly provide. I read the existing framework as granting considerable operational discretion within negotiated boundaries. (avalon.law.yale.edu⁵)

Greenland’s government in Nuuk occupies a distinct position. Self-government gives it legislative and executive authority over transferred domestic fields, while defense and security remain responsibilities of the Danish Realm. Copenhagen must notify Nuuk ahead of negotiations on international agreements particularly important to Greenland and submit them for comments before conclusion or termination. If Denmark concludes one without Greenlandic consent, it must, to the widest extent possible, have no effect for Greenland. That qualified protection is stronger than optional courtesy, but weaker than an unqualified veto. (stm.dk⁷)

Nuuk’s participation at signature would therefore matter enormously without answering every operational question afterward. Greenlandic authorities are also bound by international obligations applying to Greenland and binding on the Realm. My inference is that genuine initial consent could authorize activities that a later Greenlandic government could not simply block. An agreement’s recognition of self-determination needs to be read alongside its substantive commitments, rather than treated as a substitute for them. (stm.dk⁷)

The reported restrictions on outsiders deserve separate scrutiny. A binding ban on non-NATO bases or particular investments could narrow future Greenlandic choices even if American construction rights barely changed. Reuters attributes those restrictions, and survival after independence, to an unnamed American official. Such provisions could be significant concessions. But excluding another country does not by itself give Washington authority to select military sites, issue mining permits or govern Greenland’s economy. Those would require separate textual support. (internazionale.it³)

Nor should anyone promise that existing American access can be canceled at will. Article XIII of the 1951 agreement requires mutual consent for amendments; Article XIV ties its duration to that of the North Atlantic Treaty. There is no ordinary notice-and-exit clause in that text. Long duration, by itself, would therefore be a poor measure of what Washington has newly gained. (avalon.law.yale.edu⁵)

Enforcement is another unresolved distinction. The 2004 amendment routes unresolved disputes through committee or diplomatic consultation, without expressly imposing automatic suspension. It also supersedes the original agreement’s jurisdiction provisions with corresponding NATO rules governing visiting forces. Operational freedom should not be mistaken for comprehensive American jurisdiction. (govinfo.gov⁶)

I would judge the new agreement by the approvals it removes, the territory it opens and the means it leaves for restricting or ending added rights. The public record currently establishes extensive existing access and a pending agreement; it does not supply the signed provisions needed to verify permanent control. Copenhagen’s sovereignty assurances cannot resolve that omission, and Washington’s victory announcement cannot fill it. Until the operative text is public, the defensible conclusion is bounded American access with potentially important changes still unverified, not a completed transfer of Greenland’s security decisions to Washington.
