NATO's Strategic Resolve ensures global stability

Global Watch | 2026-04-15

The global security environment is more contested today than at any point since the end of the Cold War and has prompted widespread European rearmament in response to sustained Russian aggression in Ukraine.

Adversaries are increasingly challenging the post-1945 order through rapid nuclear expansion, advanced technologies, and deeper strategic cooperation among revisionist states.

Recent developments, including Russia's nuclear signaling and growing China-Russia coordination, have sharpened the focus on credible deterrence.

In this landscape, NATO remains one of the world's most consequential collective defense alliances, projecting strength and cohesion to deter aggression.

NATO does not directly possess nuclear weapons. Its nuclear deterrent relies primarily on the United States, with additional support from the independent nuclear forces of the United Kingdom and France.

Together with strong conventional forces and nuclear-sharing arrangements, these capabilities form the core of the Alliance's security guarantee.

The nuclear foundation

The United States maintains a full nuclear triad of land-based intercontinental ballistic missiles, submarine-launched ballistic missiles, and strategic bombers.

These forces are undergoing significant modernization, including through the Sentinel ICBM and B-21 Raider programs, and continue to provide the supreme guarantee of NATO security, as the Alliance has repeatedly affirmed.

The United Kingdom's submarine-based deterrent and France's air- and sea-based nuclear forces add further depth and resilience.

NATO Secretary General Mark Rutte underscored the importance of this posture following the Alliance's Steadfast Noon exercise in October 2025, stating: "We need to do this because it helps us make sure that our nuclear deterrent remains as credible, safe, secure, and effective as possible."

Complementing these strategic forces are forward-deployed U.S. tactical weapons in Europe, which allied aircraft would deliver under strict political control. This burden-sharing arrangement reinforces the political cohesion that underpins deterrence.

Several European allies operate dual-capable aircraft that form an integral part of this shared deterrent posture. These aircraft, drawn from multiple nations, undergo regular training and certification to ensure they can execute their assigned nuclear roles if required by the Alliance.

This practical demonstration of collective responsibility not only distributes the operational load but also sends a unified political signal that any threat to one member will be met by the combined resolve of all.

Multi-domain superiority

NATO's strength extends well beyond nuclear capabilities.

The Alliance is investing heavily in integrated air and missile defense, electromagnetic spectrum operations, space resilience, and cyber defense.

These efforts are designed to address a broad range of threats, from hypersonic missiles and anti-satellite weapons to cyberattacks and hybrid tactics. They also help reduce vulnerabilities associated with critical technology supply chains.

Through exercises and ongoing capability development, NATO is working to strengthen its effectiveness across contested domains.

Its Integrated Air and Missile Defense system connects sensors, interceptors, and command networks across member states, creating a layered defensive architecture that complements national capabilities.

Growing cooperation among adversaries adds urgency to these efforts.

The so-called "no-limits" partnership between Russia and China, combined with North Korean troop deployments and Iranian support, has introduced new strategic risks.

This alignment presents challenges for NATO across multiple theaters, from Europe to the Indo-Pacific.

Even so, NATO's greatest asset remains its unity.

With 32 members pursuing higher defense spending and greater interoperability, the Alliance continues to reinforce the credibility of its deterrent posture.

In an increasingly dangerous world, deterrence grounded in modernization and solidarity remains a central element of preserving peace.

As threats evolve, NATO's continued investment in credible capabilities and strategic cohesion will be critical to meeting the challenges of the 21st century.
