H.R. McMaster’s Dereliction of Duty is less a history of Vietnam than a study in how governments slide into war without disciplined alignment between objectives, assumptions, and accountability. Viewed through that framework, current talk of military action against Iran reveals familiar vulnerabilities.
The most immediate concern is the gap between rhetoric and operational clarity. Terms like “deterrence” and “credibility” describe aspirations, not end states. A strategy requires specificity: what precise condition would constitute success, how long must it endure, and what level of force is necessary to secure it? When military deployments expand while objectives remain elastic, posture begins to substitute for policy. That is how incremental escalation acquires its own logic.
Equally troubling is the treatment of uncertainty. Coercive strategies depend on assumptions about an adversary’s red lines and tolerance for risk. If those assumptions are optimistic, escalation can outrun intention. McMaster warned that intelligence filtered through preference produces fragile plans. Any serious approach to Iran must incorporate worst-case retaliation scenarios and regional spillover into the decision calculus, rather than treating them as unlikely contingencies.
The integrity of the advisory process is also decisive. Durable decisions survive structured dissent. Senior military and intelligence leaders should be required to present best-, expected-, and worst-case pathways before force is used. Apparent consensus may signal agreement—or suppressed disagreement. Strategic resilience depends on knowing which.
Finally, accountability and termination must be addressed before initiation. Congress should be engaged in a way that clarifies national ownership, and the public should understand the potential duration and cost. Most importantly, leaders must define how a conflict would end. Without explicit termination criteria, credibility and sunk costs tend to drive escalation long after original objectives blur.
McMaster’s lesson is not restraint at all costs. It is alignment at all costs. When ends, means, intelligence, authority, and exit conditions are forced into coherence before action, strategy is possible. When they are deferred, drift replaces design—and drift is how limited wars become lasting ones.
