觊觎格陵兰岛，美国欲补齐在西半球关键拼图 |国际识局

Core Viewpoint - The recent interest of the Trump administration in acquiring Greenland is framed within the context of U.S. Arctic strategy, North Atlantic security, and competition for critical resources, highlighting a structural strategic demand in the current geopolitical environment [3][4]. Group 1: Strategic Importance of Greenland - Greenland's geographical position is crucial for U.S. military and security interests, particularly its location over the Greenland-Iceland-United Kingdom (GIUK) gap, which has historically been a key defense line against Soviet naval forces during the Cold War [4][6]. - The GIUK gap has regained importance due to the resurgence of great power competition and increased military activities in the Arctic, making Greenland's strategic position more significant [4][6]. Group 2: Military Presence and Historical Context - The U.S. has a long-standing military presence in Greenland, dating back to World War II, and has maintained military operations there under a defense agreement with Denmark since 1951 [6]. - The U.S. military's reliance on Greenland includes critical facilities like the Thule Air Base, which plays a vital role in missile warning and defense systems [6]. Group 3: Resource Competition - Greenland is believed to possess significant mineral resources, particularly rare earth elements, with estimates of around 1.5 million tons, making it a target for U.S. interests amid growing concerns over supply chain vulnerabilities [7]. - The U.S. government's focus on securing rare earth resources reflects a shift in perspective, viewing these materials as a national security issue rather than merely an economic one [7]. Group 4: Historical Precedents for Territorial Acquisition - The U.S. has a historical precedent for acquiring territory through purchase, such as the Louisiana Purchase in 1803 and the acquisition of Alaska in 1867, which were significant for U.S. expansion [8][9]. - The notion of purchasing territory has been part of U.S. expansionist strategy, although contemporary international law and principles of self-determination complicate such actions today [9][11]. Group 5: International Law and Self-Determination - The issue of Greenland's status is not merely a bilateral matter between the U.S. and Denmark but involves historical contexts, self-determination rights, and international law principles [11]. - Recent polls indicate that a majority of Greenlanders prefer independence from Denmark, with a significant opposition to joining the U.S., highlighting the complexities of any potential territorial transaction [11].
