Does the US have the right to take over Greenland?

The geopolitical landscape witnessed a remarkable development when former President Donald Trump publicly expressed interest in acquiring Greenland, sparking intense debate about territorial sovereignty and international law. This proposition, while unprecedented in modern diplomacy, raises fundamental questions about the legal frameworks governing territorial transfers between nations.

Greenland, while geographically massive, operates under a unique political arrangement as an autonomous territory within the Kingdom of Denmark. The island gained self-governing status in 2009, controlling most domestic affairs, while Denmark retains responsibility for foreign policy, security, and financial matters. This complex relationship creates a multifaceted decision-making process that would require involvement from both Greenland’s Parliament (Inatsisartut) and the Danish government for any territorial transfer to occur.

From an international law perspective, the concept of acquiring territory through purchase or annexation without consent violates fundamental principles of sovereignty established by the United Nations Charter. The 1933 Montevideo Convention on the Rights and Duties of States further reinforces that territorial integrity cannot be compromised through coercion or non-consensual arrangements. Historical precedents like the 1867 Alaska Purchase and the 1917 acquisition of the Danish West Indies (now U.S. Virgin Islands) involved mutually agreed-upon treaties between sovereign nations, establishing a legal framework that would be necessary for any potential transfer of Greenland.

The strategic significance of Greenland cannot be overstated, with its geographic position offering substantial advantages for Arctic military presence and climate research capabilities. However, any discussion of acquisition faces formidable practical obstacles, including the political will of Greenland’s population, which has demonstrated strong resistance to such proposals. The economic considerations alone—including the territory’s extensive mineral resources and fishing rights—would necessitate complex negotiations that extend far beyond simple financial valuation.

This proposition ultimately serves as a case study in the limitations of power within the contemporary international system, demonstrating that even global superpowers must operate within established legal and diplomatic frameworks when considering territorial changes.
