On Wednesday, during a routine operation in Gaza, Israeli soldiers reportedly killed Hamas leader Yahya Sinwar—seemingly stumbling into realizing a major military objective. Despite over a year’s worth of efforts, Israeli soldiers appear to have found Sinwar by accident. After killing three people during a normal operation, they apparently realized that one of the men resembled the Hamas leader. The Israeli military confirmed Sinwar’s death on Thursday.

“I think Netanyahu has zero interest in ending this war and I don’t think he’s motivated to help Biden before the elections.”

Israel and the United States have been trying to find and kill Sinwar since last October. Prime Minister Benjamin Netanyahu has cast his death as one of the main reasons for Israel’s unceasing bombardment of Gaza, saying a main war objective is “eliminating” Hamas leadership. 

With this objective met, Sinwar’s death could present a chance to end what has become a regional war. Vice President Kamala Harris said after the killing that Sinwar’s death gave “us an opportunity to finally end the war in Gaza.” But it seems unlikely that Israeli and American leaders will fully press in this moment.

A former Biden administration official said they do believe that Sinwar’s death will be viewed by the administration as “somewhat of an opportunity to secure an end to the conflict,” particularly ahead of the elections as they try to win back votes that they “certainly have lost.” The problem, the former official explained, is that “I think Netanyahu has zero interest in ending this war and I don’t think he’s motivated to help Biden before the elections.”

The next move from Israel’s government, at the moment, is unclear. On Thursday, Netanyahu stated that “the mission ahead of us has not been completed.” In an initial statement Benny Gantz, a centrist member of Netanyahu’s war cabinet, said that while Sinwar’s death is a vital goal it would not mean the end of the war in Gaza.

Sinwar was killed just over a year after he orchestrated the October 7 attack in which Hamas killed nearly 1,200 Israelis. In response, the Israeli military has leveled Gaza, killing at least 42,000 Palestinians, according to the local health ministry. (The full death toll is feared to be more than double that number, according to some public health experts.) 

Sinwar’s death comes at a time when ceasefire talks to end the war in Gaza have effectively fallen apart and the conflict has expanded throughout the region.

Israel recently launched a major invasion of Lebanon, where more than 2,000 people have now been killed. And Israel is on the verge of striking Iran in response to the ballistic missiles it launched against Israel on October 1. Iran’s decision to strike Israel came after a series of increasingly aggressive Israeli escalations in Lebanon—including extensive bombardment of residential areas in Beirut—that seemed all but guaranteed to provoke an Iranian retaliation. Hezbollah officials supported multiple ceasefire offers in early October, none of which Netanyahu accepted. (The US is not currently pushing publicly for a ceasefire between Hezbollah and Israel.)

The Biden administration could use Sinwar’s death as leverage to push for an end to what is now a regional war. This would build on a letter the United States recently sent to Israel that gave Israel 30 days to allow in more humanitarian aid to Gaza, or face potential restrictions on US weapons exports to Israel. “I don’t think [the Israeli government] will be responsive to the letter,” the former Biden official said. “I don’t think they take our threat seriously. I don’t think the US government would withhold weapons. I think this is a signal that won’t be followed through on.” (Human rights groups, according to a report in Politico, voiced similar concerns that “rules don’t apply” to Israel.)

Israel has now killed the top leaders of both Hamas and Hezbollah: Hezbollah secretary-general Hassan Nasrallah was killed in an Israeli airstrike on September 27, and in July, Israeli is widely understood to have assassinated Hamas’ political chief Ismail Haniyeh in Tehran. (Haniyeh, who was Hamas’ key ceasefire negotiator, was considered to be more moderate than Sinwar.) 

Israel has reduced much of Gaza to rubble following one of the most intense aerial bombardment campaigns in modern history. The IDF has dropped at least 75,000 tons of bombs on the territory, killed at least one out of every 55 people in Gaza, and has cut off nearly all humanitarian aid. Its actions in Gaza have reportedly violated international human rights law and—along with Hamas’ actions on October 7—constitute potential war crimes in the view of the chief prosecutor of the International Criminal Court. A case in the International Court of Justice asserting Israel is actively committing a genocide is proceeding as well.

Both Iran and Hezbollah, which is closely aligned with Iran, have signaled they would like to avoid a full-scale war with Israel that could potentially further involve the United States. The question remains whether the Biden administration is willing to use its extensive leverage as Israel’s primary weapons supplier to force an end to the conflict.
