The funeral of Hezbollah leader Hassan Nasrallah marks the end of an era for the group, with major geopolitical implications and a potential change in power dynamics in the region. Nasrallah transformed Hezbollah into a formidable political and military power in Lebanon and the wider Middle East. However, since his assassination, the organization has lost key allies and much of its power. The group's new leader, Naim Qassem, lacks Nasrallah's charisma and popularity, leaving a vacuum within the group. With Hezbollah weakened and facing military threats from Israel, rebuilding will be a difficult task.
