Welcome to the Winter 2025–26 issue of Parameters, which consists of an In Focus special commentary, two forums (Indo-Pacific Deterrence and Considerations for Modern Warfare), and the new Strategic Competition Corner.

In this Corner, Dr. Antulio J. Echevarria II, professor of strategic competition at the US Army War College, critiques the essential concepts underpinning US doctrine concerning intrastate strategic competition. In this, his inaugural contribution, Dr. Echevarria discusses the shortfalls in the Joint concept of interstate strategic competition, namely, its failure to capture the true nature of that competition. A more extensive reading of the scholarly literature on strategic rivalry suggests the nature of strategic competition should be reframed to align more closely with the nature of war.

In this episode, Antulio J. Echevarria II discusses how NATO might better leverage risk to strengthen the alliance’s extended deterrence. Can NATO increase the risks and costs of war for an adversary without unduly raising the alliance’s own? Can the alliance strengthen the credibility of NATO’s extended deterrence through a proxy strategy of “waging war without going to war”?
