执意拿下格陵兰岛？从增兵到吞并，美国摆在桌面上的三个选项

Core Viewpoint - The U.S. government is exploring various options regarding Greenland, including increasing military presence and potentially acquiring the territory, despite Denmark's reluctance [1][5]. Group 1: Current Options - Denmark prefers to enhance U.S. presence in Greenland under the existing defense agreement from 1951, which previously allowed for around 15,000 U.S. troops during WWII, but has since dwindled to fewer than 200 at the Pituffik space base [2]. - Danish officials have frequently offered opportunities for the U.S. to establish more military bases on the island, but responses have been lukewarm [2]. - There is a possibility of a new defense agreement that could include more bases or even the transformation of bases into U.S. territory, similar to the UK's military bases in Cyprus [2]. Group 2: Independence and Its Implications - A majority of Greenlanders support independence from Copenhagen, especially if economic conditions improve, but only 6% favor becoming part of the U.S., with 85% opposing it [3]. - Some U.S. officials view Greenland's independence as a challenge and an opportunity, suggesting that the U.S. should provide a security umbrella to prevent potential threats from Russia [3]. - The Compact of Free Association (COFA) has supporters in Greenland, but many are cautious about exchanging one dependency for another [4]. Group 3: Concerns Over Military Action - Danish officials are taking Trump's refusal to rule out military action seriously, acknowledging that a military invasion could be straightforward due to the limited Danish military presence on the island [5]. - Danish Prime Minister Mette Frederiksen has expressed concerns that any U.S. military action would have significant repercussions for NATO and post-WWII European security [5]. - There are fears that Trump's interest in Greenland may stem from a desire for territorial expansion, reflecting his background as a real estate mogul [5][6].
