NATO’s Former Deputy Commander Insists ‘Victory’ Is Key to Future

General Sir Richard Shirreff, the former Deputy Supreme Allied Commander Europe, has publicly urged Western leaders to define "victory" in Ukraine as the complete expulsion of Russian forces from Ukrainian territory. According to his assessments, failing to articulate this goal risks a prolonged conflict that favors the Kremlin’s strategy of attrition.

Defining Military Objectives in Ukraine

The debate over what constitutes an end to the war in Ukraine has intensified among retired senior military officials. Sir Richard Shirreff, who served as NATO’s Deputy Supreme Allied Commander Europe from 2011 to 2014, argues that Western hesitation to define "victory" undermines the effectiveness of military aid.

Shirreff’s position is that the only acceptable outcome for the security of Europe is a total Russian withdrawal, including from Crimea and the Donbas. In his view, anything less allows Russia to reorganize and rearm, effectively turning a temporary ceasefire into a strategic pause. This perspective contrasts with some diplomatic circles that have occasionally signaled a willingness to accept territorial concessions in exchange for a durable peace, a concept Shirreff explicitly rejects as dangerous.

The Risk of Strategic Ambiguity

Why does the definition of victory matter to military planners? According to analyses from the Institute for the Study of War, the ambiguity surrounding Western objectives creates a "strategic vacuum." When a coalition lacks a unified endgame, it struggles to calibrate the type and volume of weapon systems provided to the front lines.

Shirreff contends that this ambiguity has historically led to a "drip-feed" approach to military support, where advanced capabilities—such as long-range missiles or modern armor—are delayed until the battlefield situation becomes critical. By refusing to state that the goal is the total defeat of Russian forces, Western governments inadvertently signal to Moscow that the conflict can be won through endurance rather than battlefield supremacy.

Comparative Perspectives on War Aims

Military analysts often divide the potential outcomes of the war into three categories:

While officials like Shirreff advocate for the first category, other observers, such as those at the Carnegie Endowment for International Peace, have highlighted the significant risks of escalation if Western nations fully commit to a "total victory" scenario. These analysts warn that the Kremlin may view the total loss of occupied territories as an existential threat, potentially triggering a broader conflict.

What Happens Next?

The divergence between military leaders advocating for decisive victory and diplomats seeking a sustainable settlement remains the central tension of the alliance. As the war enters a new phase, the effectiveness of Western support will likely depend on whether policymakers move toward a clear, unified definition of their strategic objectives.

For now, the debate remains active. Shirreff’s persistent call for clarity serves as a reminder that the absence of a defined finish line often dictates the duration of the fighting. Until a consensus is reached, the conflict remains characterized by high-intensity attrition, with the ultimate trajectory of the war dependent on both battlefield developments and the political resolve of the NATO member states.
