The killing of Hezbollah leader Hassan Nasrallah marks a significant blow to the Lebanese Shia movement, following a series of Israeli attacks on its leadership and communications network. Analysts question Hezbollah’s ability to maintain its political power and resist a potential Israeli invasion. Since Lebanon’s civil war ended in 1990, Hezbollah has dominated Shia politics, gaining power and becoming a polarizing force. Accusations of involvement in political assassinations and internal conflicts have marred its reputation. Hezbollah’s support for Syrian President Bashar al-Assad during the uprising further complicated its standing.
