Yahya Sinwar was the late leader of Hamas and the architect of the attacks of October 7th 2023 on Israel. Under Sinwar and his brother Muhammad, Hamas's Gazan branch dominated the movement. Muhammad Sinwar, the military chief, was confirmed dead on June 8th 2025 after his body was found in a tunnel beneath the European Hospital in Khan Younis.
Hamas continues to be guided by Sinwar's hardline approach. Since the war, the group has filled its ranks by istimzaj (consultation) rather than election, favouring continuity over reform. "Sinwar's ghost still rules," according to a Gazan observer. "The war did nothing to change them."
The function of the expert is not to be more right than other people, but to be wrong for more sophisticated reasons.
