Curtis M ScaparrottiEdit
Curtis M. Scaparrotti is a retired United States Army general who held several of the U.S. military’s most consequential commands, culminating in service as the NATO Supreme Allied Commander Europe (SACEUR). His career spans assignments in Europe and the Korean peninsula, where he helped shape the posture of American forces and allied defenses at a moment of renewed great-power competition. As a senior commander, Scaparrotti emphasized readiness, interoperability with allies, and a robust deterrent posture designed to preserve peace through credible consequences.
A career Army officer, Scaparrotti’s ascent through the ranks included leadership positions in both the European theater and the Korean theater. He is widely associated with holding joint commands that linked U.S. forces with allied capabilities in Europe and the Asia-Pacific region, and with steering the alliance’s approach to deterrence in the face of Russian aggression and a rising China. In NATO, he led efforts to strengthen the alliance’s defense and deterrence posture, integrate modernization across member militaries, and ensure that European security remained a shared responsibility of allied nations and the United States. His leadership period coincided with evolving threats that demanded a more capable, ready, and interoperable coalition under the umbrella of NATO.
Career
Scaparrotti’s career in uniform spanned several decades and theaters, reflecting a pattern common to leaders who ascend to the highest levels of joint command. He held senior positions in both the United States Forces Korea and in European command structures, culminating in the role of the head of the U.S. European Command as well as the NATO post that oversees operations across the continent. In those capacities he oversaw planning, training, and operations designed to deter aggression, defend allies, and deter adversaries by credible capability and readiness. His work in Europe was marked by a push to modernize alliance forces, improve interoperability among diverse national militaries, and sustain a forward posture capable of responding to a range of contingencies. In Korea, he was involved in directing a complex alliance command structure that remains central to the defense of the Korean Peninsula and to deterring a possible conflict on the peninsula.
As SACEUR, Scaparrotti was responsible for NATO’s operational command and for guiding alliance strategy in a security environment characterized by renewed Russian assertiveness, cyber and space contest, and rapid technological change. In that role, he emphasized three linked priorities: reliable deterrence to prevent conflict, strong alliance cohesion to ensure that allies meet shared commitments, and readiness and modernization to keep pace with evolving threats. He supported deepened interoperability among allied forces and the integration of new capabilities—such as cyber operations, air and missile defense, and advanced intelligence, surveillance, and reconnaissance—to maintain deterrence while maintaining the credibility of the alliance.
Policy and defense priorities associated with Scaparrotti’s leadership reflected a flexible, force-projection-centric approach. He argued for a defense investment path that prioritized mobilization and readiness, the maintenance of a credible nuclear posture as a stabilizing factor in European security, and a robust, multilayered approach to deterrence that integrated conventional forces with alliance-wide resilience and rapid-response capabilities. He also underscored the importance of sustaining a strong transatlantic bond, ensuring that the United States and its allies share risk and responsibility in deterring aggression and maintaining a balance of power favorable to liberal democracies.
Deterrence, alliance, and modernization
From a strategic perspective, Scaparrotti’s work reflected a long-standing view that secure peace rests on credible deterrence backed by capable allies. He argued that deterrence is strengthened not only by forward-deployed forces but also by regular exercises, interoperability with partner militaries, and sustained modernization across services. His approach presupposed that a stable peace follows from adversaries recognizing that aggression would be met with a coordinated, capable, and multinational response. In the European theater this meant reinforcing the NATO alliance with a capable, integrated set of forces and ready interoperability with member states, while in Asia it meant reinforcing the deterrent value of the U.S.–ROK alliance and allied partnerships that can respond to aggression or coercion in the region.
Key policy themes associated with his leadership include - strengthening deterrence through forward presence and readiness across the Atlantic and in the Pacific, linked to a credible and multi-domain posture; - modernizing alliance forces to address contemporary threats, including cyber and space domains alongside more traditional domains of warfare; - sustaining a robust nuclear posture as a foundational element of strategic stability in Europe; and - reinforcing a durable and capable transatlantic bond that can deter, deter, and if necessary, defeat aggression.
These priorities were advanced through close collaboration with allied leaders and U.S. policymakers, and they were intended to translate into more capable and tenable defense postures for Europe and Asia alike.

Controversies and debates
As with any figure who holds high command responsibilities during a period of geopolitical tension, Scaparrotti’s record has been the subject of debate. Supporters on the security side of the spectrum argue that his emphasis on deterrence, allied unity, and readiness reflected prudent prudence in an era of reassertive great-power competition. They contend that credible deterrence—anchored by robust allied forces, modernization, and a strong U.S. commitment to the security of Europe and the Asia-Pacific—helps prevent conflicts by signaling to potential aggressors that aggression would be met with a decisive and coordinated response from a coalition of capable states. Advocates emphasize that preserving peace through strength makes diplomacy more effective, because adversaries know the costs of miscalculation.
Critics have pointed to the risks associated with heavy forward deployments and the potential for escalation in a volatile regional environment. Some critics argue that an assertive posture can provoke unnecessary tensions with nations such as Russia and China or heighten regional flashpoints. From this perspective, diplomacy, arms-control diplomacy, and confidence-building measures should accompany any deterrent footprint to reduce the chances of miscalculation. Proponents of a more restrained approach argue that resources could be better allocated to domestic priorities or to non-military tools of competition, such as economic resilience and diplomacy. Those criticisms, however, are often framed as calls to retreat from the deterrence architecture that many conservatives believe has preserved stability in Europe and deterred conflict since World War II.
In the debate over alliance strategy, Scaparrotti’s record is also read through the lens of budgetary and political pressures. Critics may contest the trade-offs involved in sustaining high levels of defense spending, manpower, and modernization programs while pursuing other domestic and international goals. Proponents maintain that for a global system built on liberal norms and open societies, maintaining credible alliances and modern forces is essential to deterring autocratic revisionism and securing a favorable balance of power that protects freedoms at home and abroad. The discussion often centers on how best to balance deterrence with diplomatic engagement, how to allocate limited resources, and how to manage the alliance’s responsibilities in a changing security environment.
Legacy and impact
Scaparrotti’s leadership is associated with reinforcing the credibility of the United States and its allies as a deterrent to aggression in two of the globe’s most consequential theaters. His work helped sustain a robust alliance framework in Europe, encouraged interoperability amongNATO members, and supported a defense posture designed to deter adversaries while preserving strategic stability. By prioritizing readiness, alliance cohesion, and modernization, his tenure contributed to a security architecture intended to deter aggression and maintain a peace that upholds the security interests of the United States and its partners.
