NATO allies including Denmark and Norway should exercise caution in joining aggressive US military operations in the Arctic near Russian submarine bases, according to security experts warning that new American missile defense strategies combined with NATO expansion in the region could trigger dangerous escalation with nuclear-armed Russia.

Nuclear Arms Control Treaty Expires Amid Arctic Tensions

The expiration of the New START treaty between the United States and Russia has created significant concern among Nordic governments as the last remaining nuclear arms control agreement between the superpowers comes to an end. Norwegian Prime Minister Jonas Gahr Støre expressed worries at an Arctic conference in Tromsø last week as the treaty lapsed, eliminating mutual inspections and data exchanges between Washington and Moscow.

Loss of Predictability in Nuclear Arsenal Management

The treaty previously established critical predictability by allowing both nations to inspect each other’s nuclear arsenals and exchange data about weapons stockpiles. Professor Katarzyna Zysk from Norway’s Defense University College explains that without these transparency mechanisms, uncertainty increases about whether either side might expand its nuclear weapons beyond previous limits.

However, immediate changes remain unlikely. Russia’s ongoing war in Ukraine strains its economy, limiting capacity for rapid nuclear expansion despite modernization being a national priority. Experts suggest increasing warhead numbers represents the easiest expansion path, but implementation could take years given Russia’s economic constraints and technical requirements.

Russia’s Nuclear Vulnerability and Submarine Strategy

Russia’s atomic forces are more vulnerable and lower quality compared to American capabilities, according to Professor Tormod Heier from Norway’s Defense University College and Boston University. This military disadvantage makes Russian submarines capable of launching hypersonic missiles with nuclear or conventional warheads the preferred weapons system for Moscow.

The strategic importance of Russian submarine bases near Norway, particularly at Litsafjorden just over two hours from the Norwegian border town of Kirkenes, creates ongoing surveillance challenges. Russian submarines must pass through the Barents Sea and along Norway’s Finnmark coast to reach hiding positions in the Atlantic Ocean, giving Norwegian and NATO forces opportunities to monitor their movements.

Increased NATO Presence Near Russian Bases

American and NATO forces have strengthened their presence near Russian submarine operations, making it increasingly difficult for Russian vessels to slip undetected from the Barents Sea into deeper Atlantic waters. During his previous presidency, Trump pursued a strategy emphasizing unpredictability and advanced operations closer to Russian nuclear submarines, including near the Bear Gap between Svalbard and Hammerfest.

Arctic Sentry Mission Raises Stakes

NATO is currently planning a new Arctic watchdog mission called Arctic Sentry to counter what alliance officials describe as increased Russian military activity and growing Chinese interest in the High North. The mission will incorporate Denmark’s Arctic Endurance exercise in Greenland and Norway’s Cold Response exercise under NATO’s operational umbrella.

At a Wednesday press conference, NATO Secretary General Mark Rutte remained vague about specific mission details but confirmed the expanded Arctic operations respond to strategic threats. The alliance announcement follows recent deployments including Denmark sending over 100 combat soldiers to Greenland in January 2026, with an additional 200 troops arriving as part of Operation Arctic Endurance expected to continue through the year.

Warnings Against Aggressive Patrols

Despite NATO’s expanded presence, security experts caution against overly aggressive military posturing in sensitive Arctic waters. Peter Viggo Jakobsen from Denmark’s Defense Academy warns that NATO must carefully consider how it deploys military assets in the Arctic, particularly regarding aggressive patrols near the Bear Gap between Svalbard and Hammerfest where American forces have previously operated intensively.

Jakobsen uses a vivid analogy to describe the risks of cornering a nuclear power. A snake with nuclear weapons represents an extremely dangerous predator, he explains, so decision makers must consider how hard they want to press Russia into a corner. The expiration of arms control agreements does not immediately change threat assessments overnight, making measured responses more appropriate than dramatic escalations.

The Golden Dome Shield Paradox

Trump’s proposed Golden Dome missile defense system, which he claims requires control of Greenland for optimal effectiveness, could paradoxically create greater instability rather than enhanced security according to Danish military analysts. The concept envisions a multilayered defense capable of intercepting ICBMs, hypersonic missiles, and drones to protect American territory and allies.

Risks of Defensive Superiority

Peter Viggo Jakobsen emphasizes that successful implementation of the Golden Dome shield could produce an extremely dangerous situation rather than the intended security enhancement. If the United States develops the capability to deflect Russian and Chinese attacks while maintaining its own offensive strike capability, the resulting imbalance could tempt Washington to use nuclear weapons without fear of retaliation.

The fundamental stability of nuclear deterrence depends not on arms control treaty rules but on mutual assured destruction. Each nuclear power must know that even after absorbing a first strike, sufficient weapons would survive to deliver a devastating counterstrike. This mutual vulnerability prevents nuclear war more effectively than any treaty provisions or monitoring mechanisms.

Stability Through Mutual Vulnerability

Current nuclear stability relies on Russia, the United States, and China each possessing enough protected weapons to guarantee devastating retaliation even after a surprise attack. This knowledge creates deterrence by making nuclear first strikes suicidal for the attacker regardless of initial advantages.

From a Norwegian or Danish perspective, instability does not arise only from Russian aggression but also from potential American actions, Jakobsen notes. A scenario where Trump’s Golden Dome succeeds in creating one-sided defensive superiority while eliminating mutual vulnerability would fundamentally destabilize the nuclear balance that has prevented great power wars for decades.

Strategic Recommendations for Small NATO Allies

Military strategists recommend that NATO avoid the most provocative operational areas near Russian submarine bastions while maintaining credible deterrence further south. Historical American analyses from the late 1980s, when US forces aggressively operated near the Bear Gap, now acknowledge those operations were mistakes that created excessive risks.

Focus on Southern Chokepoints

Rather than concentrating NATO naval forces near Russian submarine bases in the far north, Jakobsen suggests the alliance should focus surveillance and interdiction efforts on strategic passages further south along the line connecting Greenland, Iceland, and the United Kingdom. This approach maintains effective monitoring of Russian submarine movements without the escalatory risks of operations immediately adjacent to Russian bases.

The United States wants to maintain aggressive patrols near Bear Gap, but the question remains whether NATO as an alliance should operate there or concentrate on controlling southern straits. Pressing too hard against Russian strategic assets in their home waters risks provoking exactly the crisis that deterrence seeks to prevent.

Denmark’s Substantial Contribution

Danish Defense Minister Troels Lund Poulsen announced Wednesday that Denmark expects strong European participation in NATO’s Arctic Sentry mission and will provide a substantial Danish contribution. While specific details remain under development, the minister indicated contributions will likely include aircraft, military personnel, and naval assets from all three service branches.

Defense Chief Michael Hyldgaard will provide military recommendations for Denmark’s specific contributions to the mission. The Danish commitment comes alongside over six billion dollars in investments for Greenland defense, including additional F-35 fighter jets, P-8 maritime patrol aircraft purchases from the United States, and a new Arctic special forces team that began training in October 2025.

American Strategic Priorities

The 2026 US National Defense Strategy explicitly emphasizes guaranteeing military access to Greenland alongside the Panama Canal in what the document describes as key strategic terrain for commercial and defense purposes. This policy framework aligns with increased American activity including NORAD exercises at Pituffik Space Base and proposals for expanded presence under existing defense agreements.

Trump’s January 2026 social media posts showing images with “Greenland US Territory Est 2026” signs alongside threats of European tariffs demonstrate the pressure facing Danish decision makers. American officials have requested information about Greenland’s infrastructure repeatedly since 2025, with some reports indicating requests every six days during peak periods.

European Solidarity and Pushback

French President Emmanuel Macron linked support for Greenland’s integrity to Ukraine in January 2026 social media posts criticizing Trump’s territorial demands. European NATO allies including France, Germany, and Sweden contributed personnel to Denmark’s Arctic operations starting in January, gathering at Nuuk’s Joint Arctic Command to demonstrate solidarity against American pressure.

European leaders have proposed a Line of Deterrence involving frigates and military assets from France, the United Kingdom, Scandinavian countries, and Germany to preemptively support Denmark. These proposals reflect NATO’s internal tensions as alliance members navigate conflicting pressures between maintaining transatlantic unity and resisting what some view as predatory behavior by their most powerful ally.

Long-Term Arctic Security Outlook

The convergence of expired arms control treaties, aggressive American strategic postures, increased NATO presence, and Russian vulnerability creates a volatile situation in the Arctic that requires careful management by all parties. The melting of Arctic ice opens new shipping routes and resource access, intensifying geopolitical competition beyond traditional security concerns.

Infrastructure and Economic Dimensions

The United States announced twenty-five million dollars in upgrades to Pituffik Space Base in January 2026, including runway lighting improvements and a river bridge to enhance operational capabilities. These investments build on a four billion dollar Air Force contract from 2022 and F-35 deployments beginning in 2023 at the facility hosting approximately 200 American troops operating missile early warning systems.

Pituffik’s strategic value extends beyond immediate military applications to broader Arctic infrastructure development as climate change transforms regional accessibility. The base shifted to US Northern Command oversight in June 2025, reflecting elevated priority within American defense planning as commercial and military opportunities expand with retreating ice.

Recommendations for Measured Responses

Security experts emphasize that while Russia’s elimination of arms control transparency creates legitimate concerns, Nordic countries should avoid worst-case assumptions that could become self-fulfilling prophecies. The absence of inspection regimes does not immediately enable Russian nuclear expansion given economic constraints and technical requirements for meaningful arsenal increases.

NATO’s Arctic Sentry mission and planned exercises like the UK-led Lion Protector operation scheduled for September 2026 in Iceland demonstrate alliance commitment to regional security without requiring the most provocative operational postures. Denmark’s substantial investments in Greenland defense capabilities offer pathways to address American security concerns without ceding sovereignty or enabling destabilizing shield technologies.
