2019年，时任美国总统唐纳德·特朗普公开表示有意购买格陵兰岛，引发国际舆论哗然。尽管这一提议被丹麦和格陵兰当地政府断然拒绝，但其背后的逻辑与话术值得深入分析。首先，从地缘战略角度看，格陵兰位于北极圈内，随着全球变暖导致冰层融化，该地区蕴藏的丰富矿产资源、潜在航道以及军事价值日益凸显。特朗普政府强调‘美国优先’，试图通过扩大在北极的影响力来抗衡中俄在该区域的活动。其次，特朗普惯用‘交易艺术’式话术，将国家间关系简化为商业买卖，声称‘买下格陵兰比打仗便宜’，以此塑造自己务实、精明的谈判者形象。此外，此举也带有转移国内政治注意力的意图，在弹劾风波和选举压力下，制造外交话题以巩固基本盘。虽然购岛提议看似荒诞，却精准体现了特朗普‘以夸张言论推动议程’的沟通策略——即使目标无法实现，也能主导舆论焦点，强化其‘打破常规’的政治人设。
In 2019, then-U.S. President Donald Trump publicly expressed interest in purchasing Greenland, sparking international astonishment. Although the proposal was swiftly rejected by both Denmark and Greenland’s local government, the underlying logic and rhetoric warrant closer examination. Strategically, Greenland lies within the Arctic Circle, and as climate change accelerates ice melt, the region’s vast mineral resources, emerging shipping routes, and military significance are growing. Trump’s ‘America First’ doctrine sought to expand U.S. influence in the Arctic to counter Russian and Chinese activities there. Rhetorically, Trump employed his signature ‘art of the deal’ approach, framing international relations as commercial transactions—claiming it would be ‘cheaper to buy Greenland than to go to war’—to project an image of a shrewd, pragmatic negotiator. The move also served as a distraction from domestic political turmoil, including impeachment proceedings and election pressures, by generating foreign policy headlines to rally his base. While the purchase idea appeared far-fetched, it perfectly illustrated Trump’s communication tactic: using provocative statements to dominate media cycles and reinforce his anti-establishment persona—even if the stated goal was never realistically attainable.
