Greenland Wasn't Sold. The Arctic Control Plane Was Rewritten.

Greenland wasn't sold or annexed. The September 22, 2026 U.S.–Denmark–Greenland security agreement expands Pituffik, provides for defense areas at Narsarsuaq and Mestersvig, establishes broad U.S. military access, limits non-NATO military presence and sensitive foreign investments, and seeks continuity even if Greenland becomes independent. Pattern Nexus places the signed treaty inside its earlier Monroe Doctrine and Arctic control-plane coverage—and separates what was signed from what remains to be approved, funded and built.
