The Pentagon is negotiating with Denmark for access to three additional military sites in Greenland, marking the first U.S. expansion there in decades. General Gregory M. Guillot, head of U.S. Northern Command, revealed the plans during a congressional hearing, citing Greenland's growing strategic importance amid increasing Arctic threats.

Two of the proposed locations - Narsarsuaq and Kangerlussuaq - were previously American bases during World War II and the Cold War. Narsarsuaq offers a deepwater port while Kangerlussuaq has a long runway capable of handling large aircraft. The military is eyeing these sites for special operations forces and maritime capabilities.

Denmark faces a diplomatic dilemma as it balances its 1951 defense agreement with the U.S. against President Trump's persistent interest in acquiring Greenland. While Greenlandic residents express unease about expanded American presence, the 1951 pact gives the U.S. significant leverage. Scholars note that while Denmark could theoretically refuse, doing so risks the U.S. framing Greenland's control as a security threat.
