Yahya Sinwar
Leader of Hamas in Gaza; architect of October 7
"We have been waiting for this for years. The time has come to say: enough."
Biography
The most consequential and most ruthless figure in Hamas's history, Sinwar spent 22 years in Israeli prisons — released in a 2011 prisoner exchange — and emerged with a plan for an attack that would shatter the status quo. He reportedly ordered the October 7 attack even knowing it would result in catastrophic harm to Gaza's civilian population, calculating that Israel's response would destroy the normalization process with Arab states and force the Palestinian cause back onto the global agenda. He moved through Gaza's tunnels for a year as Israeli forces hunted him, and was killed by a chance infantry patrol in October 2024.

During his 22 years in Israeli prison, he learned Hebrew fluently, became a skilled chess player, wrote a novel, and was treated for a brain tumor by Israeli doctors — an act of humanity he reportedly referenced in planning October 7.
Key Battles
October 7 Attack
Hamas / Palestinian Factions victoryOctober 7, 2023 · 1,500 total casualties
The most deadly attack on Jewish people since the Holocaust. The failure of Israel's surveillance and barrier system — considered state-of-the-art — was a catastrophic intelligence failure. The attack triggered Israel's declaration of war, the largest military mobilization since 1973, and a military campaign that would reshape Gaza entirely.
Battle of Khan Younis
Israel / IDF victoryDecember 2023 – April 2024 · 20,000 total casualties
Khan Younis was the operational center of Hamas's military command. The battle's intensity and civilian cost drove the ICJ's emergency orders demanding Israel ensure humanitarian access. The hostage crisis became increasingly acute as families of the remaining captives held mass protests in Tel Aviv.
Rafah Offensive
Israel / IDF victoryMay 7, 2024 – October 2024 · 25,000 total casualties
The Rafah offensive achieved the stated military objective of destroying Hamas's last organized military formations and killing its senior leadership. But it also produced the war's most devastating humanitarian conditions, with aid effectively blocked for months. The killing of Sinwar removed Hamas's mastermind but did not end the conflict or produce a hostage deal.
