In the months following the death of Ayatollah Ali Khamenei in US-Israeli strikes, his son Mojtaba has assumed the mantle of Supreme Leader — Iran's most consequential seat of power. Now, Israeli reports of his critical illness have prompted Iranian state media to release undated footage of him in apparent good health, a gesture that reveals as much as it conceals. The absence of a timestamp, and of the man himself from public life, reminds us that in systems built around singular authority, the health of one person can become the health of a nation.
