Iran is meticulously planning Ayatollah Ali Khamenei's funeral to prevent the deadly crowd surges that marred previous burials. Lessons learned from the chaotic funerals of Ayatollah Khomeini and General Qasem Soleimani are shaping extensive security measures, including potential helicopter deployment and cross-border coordination with Iraq. The aim is to ensure Khamenei's final rites are a display of state control, not a repeat of past tragedies.
