Background & Context
Yahya Sinwar, who led Hamas in the Gaza Strip from 2017 until his death in Rafah in October 2024, authored a handwritten document on 24 August 2022. The memo, obtained by the Meir Amit Intelligence and Terrorism Information Center and first published by Channel 12, outlined Hamas’s operational blueprint for a large-scale invasion of Israel and explicitly warned that Israel might “use all means and weapons at its disposal,” including a nuclear bomb.
Core Event: Sinwar’s 2022 Handwritten Plan
The memo detailed a simultaneous breach of the Israel-Gaza fence at 25 junctions, each to be assaulted by a “well-trained squad” of 100 fighters. In total, Sinwar envisioned a force of roughly 10,000 combatants: 2,500 for the border breaches, 2,210 to attack 221 small communities, 1,600 for eight larger towns, 1,200 for Israeli cities, and 2,000 for army bases. The document also instructed that “the goal is to expel the settlers with their vehicles,” giving “priority to children and women,” while men aged 17-50 were to be taken hostage and all phones confiscated.
Data & Statistics
- Planned fighters: ~10,000 (as above).
- Actual invaders (IDF estimate): ~5,600 total, including about 3,500 Hamas fighters, 580 Palestinian Islamic Jihad members, and 1,400 other Gazans.
- Casualties on 7 October 2023: roughly 1,200 Israelis killed, 251 abducted.
- Post-invasion regional attacks: Hezbollah launched rockets and drones the next day; additional Iran-backed groups in Yemen, Iraq and Syria struck later.
- Ceasefire: Fighting in Gaza largely ceased in October 2025 after a U.S.–brokered deal that secured the release of all remaining hostages and saw Israel free nearly 2,000 Palestinian security prisoners.
Official Statements & Responses
The Meir Amit Center described the memo as “a new revelation” that shows Hamas’s awareness of Israel’s “potentially catastrophic” retaliation. Israeli officials have not confirmed possession of nuclear weapons, and Israel remains outside the Nuclear Non-Proliferation Treaty. The document’s release follows a similar Hamas paper disclosed in October 2025 that described plans to broadcast “horrifying images” during the Oct 7 massacre.
Criticism & Opposition
Analysts have characterized Sinwar’s willingness to risk Gaza’s destruction as “irrational” and a rejection of the Mutual Assured Destruction logic that underpinned Cold-War deterrence. Commentators note that Hamas proceeded with the operation despite anticipating a possible Israeli nuclear response, viewing massive regional escalation as an acceptable price for attempting to “bury Israel.”
Conflicting Reports & Gaps
The memo’s force size (?10,000) exceeds the actual number of combatants who crossed the border (?5,600). No public Israeli source has indicated that a nuclear option was seriously considered, leaving Sinwar’s prediction unverified.
Why It Matters
The memo provides rare insight into Hamas’s strategic calculus, revealing a willingness to trigger a regional conflagration even at the cost of Gaza’s survival. It also underscores the importance of understanding non-state actors’ risk assessments, especially when nuclear escalation is invoked, for policymakers monitoring Middle-East stability.
