A week into a combined U.S.–Israeli campaign that has moved beyond strikes on proxy leaders to targets at the apex of Tehran’s system, Israeli prime minister Benjamin Netanyahu framed the operation as open‑ended: “the war will last as long as it needs to.” He has publicly urged Iranians to rise up and seize control of their country — a rhetorical bridge from military action to political transformation that masks a far riskier strategic calculation.
Netanyahu’s decision to press a “decapitation” strategy against Supreme Leader Ayatollah Ali Khamenei must be understood against the backdrop of his four decades in Israeli politics. A three‑time prime minister and the country’s longest‑serving leader, he has repeatedly rebuilt his political standing in crisis. Today he faces the most fraught moment of his career: a fractious coalition, a prolonged domestic judicial crisis, and the international fallout from the Gaza conflict all sharpen the incentives to use force abroad to consolidate authority at home.
Targeted killings have been a central strand of Israeli strategy for decades, with tangible tactical successes against Hamas and Hezbollah commanders and prior operations against Iranian nuclear scientists and IRGC leaders. In Netanyahu’s view, removing Khamenei would be the logical, if most extreme, extension of that playbook — a decisive act that could end what he characterises as an existential Iranian threat and cement his legacy.
The crucial difference is that the Iranian republic is not a personalist autocracy easily unstitched by removing one man. Iran’s power rests on an institutional architecture — the Revolutionary Guards, clerical networks, constitutionally embedded revolutionary legitimacy and a cadre of hardline elites — that has survived wars, sanctions and repeated leadership shocks. In that system a vacancy at the top is more likely to produce a successor endorsed by the IRGC than a quick collapse or liberal opening.
Netanyahu’s operation has depended on robust backing from the Trump administration: carrier strike groups, basing access and a willingness to share the strategic burden have granted Israel the operational cushion to act. But U.S. support is conditional and politically contested; prolonged escalation or domestic U.S. opposition could leave Israel more exposed. Moreover, neither government has publicly produced incontrovertible evidence that an Iranian nuclear breakout is imminent enough to render such an extraordinary strike the only viable option.
So far Tehran’s response has disproved hopes of a rapid, one‑sided campaign. Iran has launched missile strikes against Israeli territory and U.S. bases in the region, moved to pressure Gulf energy infrastructure and raised the spectre of chokepoint disruption in the Strait of Hormuz. The conflict is diffusing across multiple theatres rather than collapsing into a single decisive encounter, sharpening regional anxieties in states from Saudi Arabia to the UAE and complicating Washington’s diplomatic manoeuvring.
The parallels Western strategists invoke — Iraq in 2003 and Libya in 2011 — offer cautionary lessons. External force can topple regimes but rarely builds stable post‑conflict orders. Unlike Iraq or Libya, Iran lacks a credible exile alternative or an internal coalition capable of stepping into a vacuum and managing reconstruction. Netanyahu’s vision of a post‑Khamenei peace remains a strategic aspiration rather than a practical blueprint.
Domestically, the operation has bolstered Netanyahu’s wartime image and temporarily muted political dissent, reinforcing the immediate political calculus that likely informed his decision. Yet history will judge him by the endgame, not the opening salvo. If the campaign spirals into a protracted, regionwide confrontation or triggers entrenched countermeasures from Tehran, the gamble could redefine his legacy as the leader who steered Israel into an unpredictable and costly war.
The operation thus presents a binary risk: if it achieves the narrow goal of degrading Iran’s immediate capacity to project power and does so without sparking wider conflagration, Netanyahu can claim historic success. If it fails to produce decisive political change or provokes sustained retaliation, the costs for Israel, U.S. regional strategy and Middle East stability will likely be severe and long‑lasting.
