One hundred days after Hamas gunmen broke out of Gaza to launch the deadliest attack in Israel’s history, tens of thousands of Palestinians have been killed, Gaza lies in ruins and the Middle East is sliding towards a wider, more unpredictable conflict.

For both Israelis and Palestinians, the war has been a trauma that looks likely to last for years, deepening the hostility and mistrust that have stood in the way of peace for more than 75 years.

“No one will win,” said Rebecca Brindza, a spokesperson for families of the 240 Israelis and foreigners seized as hostages during attack on communities around the Gaza Strip that opened the war on Oct. 7.
