Editor's Note: On Sept. 28, Hezbollah confirmed the death of its leader, Hassan Nasrallah; he died in a Sept. 27 Israeli airstrike in Beirut, Reuters reported Sept. 28. He was killed alongside top Islamic Revolutionary Guards Corps Gen. Abbas Nilfourshan, according to Iranian state media. Nasrallah's death is a major political and security blow to the militant group, capping a campaign of assassination against top Hezbollah commanders that began when Hezbollah entered the Gaza War alongside Hamas in October 2023. It will create temporary organizational challenges for the militants and disrupt aspects of its command and control while a successor is chosen and morale across the movement is low, giving Israel a window of opportunity to escalate strikes against Hezbollah across Lebanon in an attempt to force the militant group to exit the Gaza War.
