Human-rights lawyers hope to close some gaps in international law, whether by new agreements (some call for a special tribunal to prosecute Russia for aggression) or by existing courts extending their remit. They also want new curbs on ai and autonomous weapons. But they cannot hold back states bent on violence. Arrest warrants limit leaders’ international travel. But don’t expect to see Mr Putin in the dock.

So what is the point of the court battles? Lawyers offer three answers: to impose a reputational and perhaps economic cost on those who spill blood wantonly; to strengthen the negotiating hand of their victims in future diplomatic talks; and, at a minimum, to establish a credible historical record of atrocities. Confronted with an “epidemic of inhumanity”, Mr Khan has argued, the world must “cling to the law” more tightly. The unspoken danger is that, should he and others fail to curb the horrors, the law will collapse and there will be little left to hold onto.
