TEHRAN, Oct 18* — Israel has dealt a significant blow to Hamas by reportedly killing its chief, Yahya Sinwar, who was behind the October 7 attacks. However, it remains uncertain if his death will hasten the end of the ongoing Gaza war.

Sinwar, 61, had been a key target since the attacks and was described by Israeli officials as a “dead man walking.” His death follows the killing of Hamas political leader Ismail Haniyeh in Tehran, leaving the group facing a leadership crisis.

Israeli Prime Minister Benjamin Netanyahu warned that the conflict is not over and offered terms for Hamas militants to surrender or release hostages taken on October 7. Analysts suggest that Sinwar's death could shift the balance within Hamas, which has been marked by a preference for military solutions over political negotiations.

The conflict has resulted in significant casualties, with the Hamas attack killing over 1,200 people in Israel, while Israeli military actions in Gaza have claimed around 42,438 lives, mostly civilians. Despite Sinwar’s death being celebrated in Israel, experts warn that Hamas will not simply vanish without a viable alternative.

There are hopes that this event may reopen negotiations for a ceasefire and the release of hostages, with pressure mounting on Israel to reach a deal. However, uncertainties remain regarding Gaza's future governance and security arrangements. Critics argue that Netanyahu lacks a comprehensive post-war strategy, though some believe he may leverage Sinwar's death to declare a victory.

The dynamics may shift if Sinwar’s potential successor holds different views, but concerns persist that a replacement like his brother Mohammed Sinwar could maintain a hardline stance.
