NextFin News - In a stark departure from decades of diplomatic protocol, Danish Prime Minister Mette Frederiksen openly questioned the future of the transatlantic alliance on Tuesday, January 27, 2026. Speaking at a town hall-style meeting in Berlin, Frederiksen admitted she is no longer certain how long the United States will remain a reliable ally to Europe. The comments were made during a high-stakes diplomatic tour of European capitals, including meetings with German Chancellor Friedrich Merz, as Denmark seeks to shore up continental support against renewed American pressure regarding the sovereignty and strategic control of Greenland.
The catalyst for this diplomatic rift is U.S. President Trump’s aggressive reorientation of American foreign policy, which has recently focused on the Arctic. According to The New York Times, U.S. President Trump has mused about using economic or military force to secure ownership of Greenland, later announcing a vague "framework" agreement with NATO Secretary General Mark Rutte without the explicit consent of the Danish government. Frederiksen described the current situation as "awkward and difficult," stating that while she remains "trans-Atlantic in her heart," the erosion of traditional norms suggests that the "old world order is now gone."
This shift in rhetoric from Copenhagen reflects a deeper systemic anxiety permeating European chancelleries. The uncertainty is not merely about a single island but about the predictability of American security guarantees that have underpinned European stability since 1945. Frederiksen’s admission that she "doesn’t know what will happen in the U.S." serves as a public acknowledgment that Europe can no longer take the American security umbrella for granted. This sentiment was echoed by EU diplomats who told Reuters that the Greenland episode has "badly shaken confidence" in the relationship, leading many to view the U.S. President as a figure Europe must now actively stand up to rather than simply follow.
The strategic implications of this fallout are already manifesting in calls for radical military self-reliance. Frederiksen urged European nations to dramatically accelerate their defense spending with the goal of achieving full military independence by 2030. This timeline is considered extraordinarily ambitious by security experts, yet it underscores the perceived urgency of the threat. For Denmark, the pressure is particularly acute due to the 1951 defense treaty that allows the U.S. significant latitude in Greenland. While Frederiksen has not ruled out revising this treaty, she has established a firm "red line" against any transfer of sovereignty, a position that directly clashes with the U.S. President’s stated ambitions.
From an analytical perspective, the Greenland dispute is a microcosm of a broader transition toward a multipolar world where traditional alliances are being replaced by transactional diplomacy. The U.S. President’s focus on Greenland is driven by the island’s vast untapped rare earth minerals and its critical position in Arctic shipping lanes—assets that are becoming central to the 21st-century economy. By framing the issue as a matter of "common security" against Russian and Chinese influence, the U.S. administration is attempting to leverage NATO to achieve bilateral territorial goals. However, this strategy risks alienating the very allies required to contain those rival powers.
Data from recent defense summits suggests that while NATO allies have increased spending—reaching an average of 2.3% of GDP across the bloc in 2025—the psychological shift toward "strategic autonomy" is a newer and more volatile development. If Denmark and its neighbors successfully pivot toward a more independent defense posture, the structural role of the U.S. in Europe will diminish. This could lead to a fragmented security environment where European nations form smaller, more agile coalitions, such as the Nordic-German energy and security partnerships recently highlighted by Frederiksen’s visit with Merz.
Looking forward, the reliability of the U.S. alliance will likely remain a central theme of European politics through 2026. The upcoming forum in Paris, where Frederiksen will meet with French leadership, is expected to further solidify a European front that prioritizes sovereignty over traditional alignment. As the U.S. President continues to use tariffs and unconventional threats as diplomatic tools, the "transatlantic rift" may evolve from a temporary disagreement into a permanent structural separation. For global markets and geopolitical strategists, the primary takeaway is clear: the era of unquestioned American leadership in the West has entered a period of terminal volatility, forcing allies like Denmark to prepare for a future where they must stand alone.
