Sinwar's October 7th Gamble - Did It Pay Off?

Conflict Tracker

The Middle East Yahya Sinwar grew up in Gaza’s Khan Younis refugee camp, the son of displaced parents. His childhood unfolded amid deprivation and, from 1967, Israeli occupation. Gaza became the centre of his worldview: a homeland whose confinement he was determined to break, but which seemed destined to remain an eternal prison.

By 2023, he saw the regional order moving against him. Arab governments were building relationships with Israel through the Abraham Accords, while Saudi normalisation threatened to deepen Hamas’ isolation. The fear was that Palestine would become a question the region had learned to live without resolving.

Yet Sinwar also saw an opportunity. Closer relationships with Iran, Hezbollah and other armed groups appeared to offer the military weight needed to interrupt that trajectory. His gamble combined fear of marginalisation with confidence that a major attack could ignite a confrontation Israel would struggle to contain.

On October 7, Hamas and other militants attacked southern Israel, killing civilians and soldiers and taking hostages. The border had been breached. Sinwar’s larger calculation now depended on what followed: whether his partners would turn a Hamas offensive into a sustained regional war.

They entered the fighting, but each did so according to its own interests. Shared opposition to Israel did not erase differences over how much to risk, when to escalate or what to preserve. The alliance could open additional fronts without providing the protection Sinwar expected.

As Israel’s campaign devastated Gaza and degraded Hamas, that gap became increasingly consequential. Hezbollah’s intervention brought severe losses to its leadership and military capabilities, weakening the organisation that had represented one of Israel’s most formidable neighbouring adversaries.

Assad’s subsequent collapse had multiple causes, but its strategic consequences extended beyond Syria. Iran lost an important state partner, while the routes and relationships through which it sustained regional influence became harder to maintain. The network Sinwar had regarded as strategic depth was itself becoming exposed.

Iran remains standing, but battered. Its survival does not automatically restore deterrence or rebuild its partners. Its longer-term position depends on resources, domestic stability and the ability to sustain influence under continued pressure.

Sinwar did not live to see the full consequences. In October 2024, a drone filmed him wounded inside a ruined building, throwing a stick towards it shortly before his death.

By October 2026, he had disrupted the regional order he feared, but at a catastrophic cost to Gaza and to the alliance he expected would protect it.

One unresolved question hangs over the beginning of that story. Reports allege Netanyahu received advance warnings of a possible assault, which he denies. If warnings reached him, why did they fail to produce an effective response? The evidence does not establish that he wanted or deliberately permitted the attack. But it leaves open whether Sinwar’s gamble met an Israeli leadership blindsided by his intention, or one that had been warned and gravely underestimated what was coming. The more disturbing possibility… that warnings were deliberately ignored to obtain a casus belli for war in Gaza as some on the fringe have argued.
