Several senior Hezbollah commanders have been killed in Israeli strikes in recent weeks, including the group’s overall leader, Hassan Nasrallah, in Beirut on Friday.

His death marks a major moment in recent Middle East history, but the long-term consequences are uncertain. It raises a key question: Do “decapitation strikes” killing the leaders of terrorist groups cripple them?

Hezbollah confirmed his death, making him the seventh senior Hezbollah leader slain in Israeli strikes in a little over a week. They include founding members who had evaded death or detention for decades.
