What must a government be able to explain before it sends people to war — or decides to leave?
This episode examines a problem that legality alone cannot answer. A military campaign may comply with every applicable rule and still lack a legitimate justification. It may succeed through luck, or fail despite responsible judgment. And an inquiry held years later may identify what went wrong without protecting anyone from the original decision. Retrospective accountability matters, but when it arrives only after the damage is irreversible, it is closer to an autopsy than a justification.
The manuscript develops the idea of a decisional warrant: a structured justification that must exist before coercive power is exercised. A state must identify the decisive premise on which its action depends — not surround the decision with a cloud of interchangeable reasons or invent a new explanation after the original one collapses. That premise must be grounded in the evidence reasonably available at the time, honestly investigated, institutionally attributable, and connected to an achievable political end.
The warrant applies not only to beginning or escalating a war, but also to ending one. Withdrawal and settlement are themselves exercises of power because they determine who will be protected, who will be exposed, and who must live with the consequences. A settlement can provide genuine finality, or it can create immunity: transferring the remaining cost of war onto an abandoned population and then placing that decision beyond challenge. The same standard must therefore govern resort, continuation, and cessation.
Sometimes every available option is compromised. Continuing may be futile or disproportionate, while leaving may betray people who relied upon protection. The manuscript calls this terminal strain. In such cases, choosing the least harmful course does not magically make it legitimate. The actor remains responsible for trying to create better alternatives, limiting the damage, preserving affected people’s agency, explaining the choice, and carrying the unresolved burden rather than exporting it to those least able to resist.
Finally, the episode turns to the archive. Governments are often judged through records they created and controlled themselves. Those records may preserve everything needed to defend the institution while omitting the experiences of the displaced, exposed, or defeated. A legitimate system therefore requires a correction-capable record: an archive that preserves not merely what would justify the decision, but what a genuinely independent body would need to identify error, mitigate continuing harm, provide remedies, and prevent recurrence. Secrecy may sometimes be necessary, but permanent secrecy that places coercive decisions beyond every possible challenge cannot provide full answerability.
The central argument is demanding but simple: coercive power is legitimate only when it remains answerable to the people who must live in the world it creates. Force must answer before it acts, while it continues, when it ends, and for as long as its consequences endure.
