If Trump Targets Iran’s Supreme Leader, Will the Region Break — or Harden?

The stakes and the precedent

The idea that a single strike could topple Iran is seductive — but wrong. Iran is a regional power, a major oil producer and a geographic bridge from the Caspian to the Strait of Hormuz. It is also one of the world's few theocratic states, where clerical authority is embedded in multiple institutions. The 2020 U.S. strike that killed Qasem Soleimani showed the shock value of decapitation strikes; but will killing Ayatollah Ali Khamenei (哈梅内伊) — or attempting to — produce the same, or something far darker? It has been reported that U.S. intelligence tracked Khamenei’s movements closely in recent months, and reportedly some Western outlets claim detailed surveillance preceded any contemplated action. Those reports remain unverified.

Who wants what — and why

Israel’s hostility toward Iran is existential in tone. Jerusalem fears not just missiles or drones, but the political signal of Tehran crossing a nuclear threshold. Prime Minister Benjamin Netanyahu’s push for military pressure has domestic roots: his fragile coalition and legal troubles make decisive external victories politically valuable. Washington’s calculus is different. President Donald Trump has shown a preference for dramatic, rapid actions that can be executed by executive order — the Soleimani strike is the clearest example — but he also faces a base sceptical of open-ended wars and a domestic legal-political environment that limits sustained engagement. Sanctions and trade policy are tools short of invasion, but they cannot easily rewrite Iran’s internal bargaining among clerics, the Revolutionary Guard, political families and state institutions.

What would actually change

Iran is not Iraq in 2003 or Libya in 2011. Its power is distributed across a complex web: clergy, elected institutions, the Islamic Revolutionary Guard Corps, and decentralized local networks. Removing one leader would be traumatic, but not necessarily regime-ending. In a crisis, the IRGC’s political influence typically rises and security-tied succession mechanisms harden; the result is often more nationalist, securitized policymaking rather than liberal opening. The longer any conflict lasts, the more Iran’s internal politics tilt toward the hardliners who can marshal force and patronage.

So how will the world change? A strike might deliver a short-term shock and dramatic headlines. But strategic realities — geography, oil chokepoints, sanctions regimes and resilient Iranian state structures — mean the likely outcome is prolonged regional tension, greater IRGC sway in Tehran and higher risk of proxy escalation across the Levant, the Gulf and beyond. Quick wins are possible. Lasting solutions are not.
