丹麦首相梅特·弗雷德里克森访问格陵兰岛，以示对特朗普撤回吞并该岛威胁以及美丹就北极防务问题重启谈判的支持。特朗普曾提议在美国格陵兰岛部署导弹防御系统，但丹麦和格陵兰岛均已排除放弃主权的可能性。双方的讨论可能涉及重新谈判1951年的防务条约，重点将放在安全安排上。 Danish PM Mette Frederiksen visited Greenland to show support amid Trump's reversed threats on acquiring the territory and new US-Denmark talks on Arctic defense. Trump suggested a US missile defense system on Greenland, but Denmark and Greenland have ruled out ceding sovereignty. Discussions may involve renegotiating a 1951 defense pact, with a focus on security arrangements.
