Initial hopes in the US and Israel that the death of Iran’s Supreme Leader would lead to the collapse of the Islamic Republic have not materialized. Four months after his death, Iran is holding a state funeral for Ayatollah Ali Khamenei, demonstrating the regime’s resilience. Security officials and experts believe this event signals the survival of the Islamic Republic and the rise of a new, more deeply rooted generation of leaders. This new leadership is described as more intransigent and ruthless than its predecessor, having been hardened by recent conflict. The regime, in power since 1979, appears not only to have survived but to have become more formidable. This suggests a significant shift in the political landscape, with analysts warning of a "new Iran" emerging.
