Sverre Diesen: The US Security Guarantee Is Effectively Dead

The End of the American Security Umbrella?

For decades, the bedrock of European security has been the unwavering security guarantee from the United States. But, former Chief of Defence Sverre Diesen argues that this guarantee is, for all practical purposes, dead. The core of the issue is simple: a guarantee characterized by uncertainty is no longer a guarantee.

The tension in transatlantic relations has peaked under the Trump administration. While politicians often insist that the US remains committed to its NATO obligations, Diesen suggests this narrative may be driven by a fear of the consequences of admitting the truth. There is a growing concern that admitting the guarantee is gone could develop into a self-fulfilling prophecy.

Pro Tip: When analyzing geopolitical stability, look beyond official diplomatic statements. True security is found in predictable commitments, not in the rhetoric of shifting administrations.

The risk is that the US, as the hegemon of the world order it created, is abandoning its role. This shift potentially transforms the global stage into a state of anarchy, where international norms erode and other powers feel emboldened to act without restraint.

A New Strategic Blueprint for Scandinavia

While all of Europe faces uncertainty, the stakes are significantly higher for Norway, Sweden, and Finland. Due to their geographical position—isolated from the rest of the continent by water and situated on the edge of the Russian landmass—these nations are more dependent on the US than their European neighbors.

Only a superpower with the capability to transport massive military forces across the ocean can effectively provide relief to this region. If American support vanishes, Scandinavia faces a critical strategic crisis.

Did you recognize? Norway, Sweden, and Finland are described as “minor states in Russia’s shadow,” making integrated regional defense a necessity rather than a choice.

The proposed solution is the development of a strong, integrated Scandinavian defense. By creating a collective defense capability that is greater than the sum of its national parts, these countries can achieve a strategic synergy. While this won’t make them entirely independent of allies, it provides a vital layer of security in an unstable environment.

The Technological Revolution in Modern Warfare

The ongoing conflict in Ukraine is not just a territorial struggle; it is the catalyst for a technological revolution. Experts suggest that the changes in warfare emerging from this conflict are as fundamental as the invention of the internal combustion engine or nuclear power.

Are US Security Guarantees Acceptable to Russia?

This revolution is reshaping how nations prepare for future threats. The ability to adapt to these rapid technological shifts will likely determine which powers remain relevant in the coming decades. For Europe, the challenge is whether it can lift its collective defense capability prompt enough to match both Russian aggression and the potential absence of US support.

Understanding the Russian Zero-Sum Game

A recurring mistake in Western diplomacy is the belief that dialogue can change Russia’s perspective on the West. According to Diesen, this is a fundamental misunderstanding of Russian strategic culture.

For Russia, security is viewed as a zero-sum game: “I am safe to the extent that you fear me.” This mindset is rooted in deep historical and cultural differences, where compromise is often perceived as a sign of weakness rather than a diplomatic victory.

The only language that consistently resonates in this framework is firmness. While Russia may accept boundaries when met with strength, they will inevitably test those boundaries again the next time an opportunity arises.

FAQ: The Future of European Security

Can Europe defend itself without the United States?
Technically, yes, but the practical challenge is political. There is significant doubt about whether European nations can agree across borders to establish a defense capability on the same level as the previous US-led system.

Why is Scandinavia more vulnerable than Central Europe?
Because of its geography. Being isolated from the main European landmass means Scandinavia relies on a superpower capable of crossing the ocean to provide large-scale military reinforcement.

What is the “zero-sum game” in Russian strategy?
It is the belief that security is gained only by making the opponent feel insecure. In this view, any gain for the West is seen as a direct loss for Russia.

What do you think? Is a fully integrated Scandinavian defense the answer to US uncertainty, or should Europe focus on a single, unified continental army? Share your thoughts in the comments below or subscribe to our newsletter for more strategic analysis.
