The world's leading military powers are recalibrating their defense doctrines, moving away from assumptions of swift, decisive operations and toward strategies designed for extended, inconclusive confrontations. Defense establishments across NATO member states, China, and Russia have been updating war-gaming assumptions, procurement priorities, and alliance frameworks to reflect this evolving reality.
The End of the "Short War" Assumption
For much of the post-Cold War era, major military planners operated under a doctrine shaped by rapid dominance — the idea that technological superiority and precision strikes could bring conflicts to a quick resolution. The wars in Iraq and Afghanistan, followed by Russia's prolonged campaign in Ukraine, have significantly eroded confidence in that model.
Defense ministries across Europe and North America have begun restructuring their logistics chains, industrial production capacity, and reserve force systems to sustain operations over months or years rather than days or weeks. The European Union has formally acknowledged the need to rebuild defense industrial capacity that atrophied after the Cold War ended.
China and the Long-Horizon Approach
China's defense planning has long incorporated assumptions of prolonged engagement. Military doctrine published by the People's Liberation Army emphasizes multi-domain operations and the capacity to absorb and outlast an adversary rather than defeat them rapidly. Recent increases in naval construction and strategic stockpiling reflect a posture calibrated for endurance rather than speed.
Russia's Recalibration
Russia's experience in Ukraine has forced a significant revision of its own military assumptions. After early operational setbacks, Russian forces shifted toward a war of attrition — a model that prioritizes mass, industrial output, and territorial pressure over rapid maneuver warfare. Western intelligence assessments have noted substantial increases in Russian munitions production since the conflict began.
Implications for Alliance Structures
The shift in strategic thinking is reshaping alliance commitments. NATO members have faced growing pressure to raise defense spending and pre-position equipment and supplies rather than rely on rapid reinforcement. In the Indo-Pacific, the United States has been deepening logistics arrangements with regional partners, reflecting similar concerns about sustaining operations far from home bases.
Remaining Questions
Whether democratic governments can sustain public and political support for long-term defense investments — without the immediacy of active conflict — remains an open question. How smaller states position themselves between competing great-power blocs in a prolonged-competition environment is also unresolved.
