Nuclear Deterrence: NATO’s Best Defense Against Russia
NATO’s Deterrence Strategy: A Reevaluation of “Moderate Brinksmanship” in a Shifting Geopolitical Landscape
As of July 23, 2025, the geopolitical landscape remains profoundly shaped by the ongoing conflict in Ukraine and the persistent assertive posture of Russia. Three years ago, in his seminal 2022 article, “Russia’s Invasion of Ukraine and NATO’s Nuclear Credibility Crisis,” Tyler Bowen posited that NATO should adopt “moderate brinksmanship tactics” as a crucial strategy to deter further Russian expansion. Now, wiht the benefit of hindsight and a significantly evolved security surroundings, Bowen revisits his analysis to assess the effectiveness of NATO’s deterrence strategy and its implications for the future.
The Foundation of NATO’s Deterrence: Two Pillars Under Scrutiny
In the initial phase of the Biden management, NATO’s deterrence strategy towards Russia was fundamentally built upon two interconnected pillars. The first pillar focused on strengthening conventional military capabilities and readiness. this involved increasing defense spending, enhancing troop deployments along NATO’s eastern flank, conducting more frequent and complex military exercises, and modernizing military equipment. The aim was to present a credible conventional defense that would make any Russian aggression prohibitively costly and unlikely to succeed.
The second pillar centered on maintaining and reinforcing nuclear deterrence. This pillar underscored NATO’s commitment to its nuclear posture, emphasizing the readiness of its nuclear forces and the clarity of its nuclear signaling. The underlying principle was that Russia’s own nuclear arsenal, coupled with NATO’s credible nuclear deterrent, would create a strategic stalemate, preventing any escalation to nuclear conflict. This dual approach sought to deter both conventional and nuclear aggression by demonstrating both the capacity and the will to respond decisively.
Reassessing “Moderate Brinksmanship”: Lessons from the Past Three Years
Bowen’s concept of “moderate brinksmanship” in 2022 was a call for a more proactive and calibrated approach to deterrence. It suggested that NATO should not shy away from demonstrating a willingness to take calculated risks, thereby signaling resolve and raising the perceived cost of Russian aggression without crossing into outright confrontation. This involved a delicate balancing act: projecting strength and commitment while meticulously managing escalation pathways.
The Evolving Russian Threat and NATO’s response
Since 2022, Russia’s actions have continued to test the boundaries of international norms and security. The protracted conflict in Ukraine, coupled with Russia’s persistent nuclear rhetoric and its willingness to engage in hybrid warfare tactics, has presented NATO with a dynamic and ofen unpredictable threat environment. conventional Buildup and Adaptation: NATO has indeed responded by significantly bolstering its conventional forces. The reinforcement of the eastern flank,with increased troop numbers and enhanced capabilities,has been a visible manifestation of this commitment. Exercises like Steadfast Defender have become larger and more complex, simulating large-scale defense scenarios.However, the effectiveness of this conventional buildup is a subject of ongoing debate. While it has undoubtedly raised the threshold for Russian conventional aggression, the sheer scale and duration of the conflict in Ukraine have also exposed the limitations and challenges of sustained conventional deterrence against a steadfast adversary. The logistical strains, the need for continuous resupply, and the political will required to maintain such a posture are significant considerations.
Nuclear signaling and Ambiguity: The nuclear pillar of deterrence has been particularly complex. Russia’s repeated nuclear threats, frequently enough delivered through veiled or explicit statements, have kept the specter of nuclear escalation alive. NATO’s response has largely been to reaffirm its commitment to nuclear deterrence without mirroring Russia’s provocative rhetoric. This has involved maintaining the readiness of its nuclear forces and conducting exercises that implicitly demonstrate its nuclear capabilities. However,the effectiveness of this approach hinges on the clarity of NATO’s signaling and Russia’s interpretation of it. The concept of “moderate brinksmanship” suggests that NATO could have been more explicit in signaling the consequences of russian escalation, thereby creating greater uncertainty for Moscow. The challenge lies in calibrating this signaling to deter without provoking.
Evaluating the Effectiveness of “Moderate Brinksmanship”
Looking back, the effectiveness of NATO’s deterrence strategy, including the potential application of “moderate brinksmanship,” can be assessed through several lenses:
Preventing Direct NATO-Russia Conflict: To a significant extent, NATO’s strategy has succeeded in preventing a direct military confrontation between NATO and Russia. The credible threat of a collective response, backed by both conventional and nuclear capabilities, has likely been a key factor in deterring russia from directly attacking NATO member states.
