TEL AVIV, Israel — Israel's killing of Yahya Sinwar, Hamas' top leader and the mastermind of the group's Oct. 7 attack, is a dramatic turning point in the brutal yearlong war that it touched off.
Sinwar's killing on Wednesday decapitates the Palestinian militant group that was already reeling from months of assassinations up and down its ranks, and it is a potent symbolic achievement for Israel in its battle to destroy Hamas.
Israelis and Palestinians have just marked a year since the deadliest fighting in their decades-old conflict erupted, and Sinwar's killing could set the stage for how the remainder of the war plays out, or even prompt its conclusion — depending on how Israel and Hamas choose to proceed.
Sinwar's death could serve as an off-ramp for Israel toward ending the war
Sinwar, who was appointed head of Hamas after its previous leader was killed in a blast in July blamed on Israel, spent years building up Hamas' military strength and is believed to have devised the Oct. 7, 2023, attack. After that assault, when Hamas-led militants killed some 1,200 people and abducted about 250 others, Israel pledged to destroy Hamas and kill each one of its leaders.
With Sinwar at the top of that wanted list, his death is a major achievement for Israel. Analysts say Sinwar's killing has presented Israel, which has struggled to articulate an exit strategy from Gaza, with an off-ramp to end the war.
''This would really be the cherry on the icing of the cake for Israel,'' said Nomi Bar-Yaacov, an associate fellow of the International Security Program at the Chatham House think tank in London. ''It should be easier to reach a deal.''
With the architect of the Oct. 7 attacks eliminated, Prime Minister Benjamin Netanyahu could now tell Israelis that one of the war's aims has been reached. Politically, that might allow him to be more flexible on a cease-fire deal that ends the war in exchange for hostages — a condition he has so far refused to accept, at least in part, critics say, because it could threaten his rule.
