Trump’s Greenland Remarks Threaten Denmark’s F-35 Deal and NATO Unity
U.S. President Donald Trump’s controversial comments about acquiring Greenland have sparked a diplomatic rift with Denmark, a vital NATO ally, and cast uncertainty over the future of the F-35 Joint Strike Fighter program, one of the United States’ largest and most complex defense initiatives.
The tensions reached a boiling point after Trump’s reportedly heated 45-minute phone call with Danish Prime Minister Mette Frederiksen, where he dismissed Denmark’s control over the Arctic island as inadequate. Trump went so far as to mock Denmark’s recent efforts to bolster its Arctic presence, ridiculing their deployment of “two dog sled teams” as insufficient to protect Greenland’s strategic value. He claimed that only the United States could secure the island and ensure global freedom, adding, “They [Denmark] can’t. They thought two dog sleds were protection.”
Denmark has been a committed partner in the F-35 Joint Strike Fighter program since 2002. The country has placed orders for 27 F-35 jets to replace its aging F-16 fleet and has actively contributed to the production, development, and sustainment of the program. Its involvement has been seen as a testament to Denmark’s alignment with NATO’s strategic goals and its long-standing defense partnership with the U.S.
However, the escalating feud over Greenland has placed this partnership at risk. Trump’s threats of military action to claim the Arctic island and the possibility of imposing tariffs on Denmark have sent shockwaves through Copenhagen’s defense and diplomatic circles. Danish officials are now grappling with the potential fallout, including the possibility that the U.S. might freeze or cancel Denmark’s F-35 orders—a scenario reminiscent of Turkey’s removal from the program after it acquired Russian S-400 missile systems.
Should Denmark’s participation in the F-35 program be jeopardized, the effects could ripple across the global supply chain. The program’s sustainability relies heavily on contributions from international partners, and any disruption could lead to cost increases, delays, and reduced trust among existing and prospective buyers. Denmark’s exclusion would also signal instability in the program, further complicating efforts to maintain a unified front among NATO allies.
Other nations involved in the F-35 program, such as Italy, Japan, South Korea, and the Netherlands, are reportedly monitoring the situation closely. Meanwhile, potential buyers like Saudi Arabia and Turkey are reconsidering their options and exploring alternative next-generation fighter jets to avoid entanglement in politically sensitive defense programs.
Adding to the uncertainty is criticism of the F-35 from within the U.S. administration and influential figures like Elon Musk, who recently described the aircraft as a flawed design. Musk argued that the F-35’s attempt to serve too many roles has made it overly complex and costly, labeling it a “jack of all trades, master of none.” He also pointed out the growing irrelevance of manned fighter jets in the age of advanced drones, further casting doubt on the program’s long-term viability.
The diplomatic fallout over Greenland comes at a time when NATO is striving to maintain cohesion amidst rising global threats. For Denmark, losing access to the F-35 would not only derail its defense modernization plans but also hinder its ability to fulfill NATO commitments. For the U.S., such actions would raise questions about its reliability as a defense partner and could erode trust within the alliance.
This incident underscores the delicate balance between defense programs and international relations. The F-35 program, already under scrutiny for its high costs and complexity, now finds itself at the center of geopolitical tensions that threaten to undermine its stability and global support.
As NATO grapples with these challenges, the Greenland controversy highlights the need for diplomacy and cooperation in addressing Arctic geopolitics without compromising alliance unity. Whether Trump’s remarks will lead to long-term repercussions for the F-35 program or remain a momentary strain in U.S.-Denmark relations remains to be seen. However, the stakes for both countries—and NATO as a whole—are undeniably high.
