伊朗伊斯兰共和国在将近半个世纪里，在多次入侵、内乱、领袖遭到袭击等危机中仍然存续，关键在于其有意设计的制度结构。该结构把国家权力分散在总统、教士体系与伊斯兰革命卫队之间，并在最高领袖Ali Khamenei的指挥下运作。表面上的权力分散并未削弱其核心统摄，反而在持续的冲突环境中强化了伊朗政权的韧性；在近年，动员、镇压与再分配资源的能力体现出其长期适应性。

作为核心枢纽的Ali Khamenei今年86岁，在位近四十年。他于1989年接替Ayatollah Ruhollah Khomeini成为最高领袖，后来集中掌握军队总司令、司法和关键国家机构任免权，其中包括由强硬派主导的Guardian Council（负责筛选所有公职候选人）。今年，伊朗面临1979年以来最激烈、死亡人数达上千人的抗议浪潮；在10月7日地区战争爆发后，伊朗战略伙伴体系和军事顾问层遭重创，但体制仍通过“strategic patience”叙事在对外强硬、对内控场之间维持平衡，并通过对异见的管理化竞争延长其统治生命线。

过去十年改革派势力明显后退。改革派可参与政治，但必须不触碰核心利益与Ali Khamenei的最高地位；Masoud Pezeshkian作为二十年来首位改革派总统，实际上是体系内的“管理性缓冲”，其忠诚度明显高于变革性议程。另一方面，Mohammad Bagher Ghalibaf与革命卫队代表了保守强硬技术官僚路线，后者在经济、核计划与黎巴嫩、叙利亚、伊拉克、也门等外部代理网络中具有决定性影响力。即使美国袭击可能压制部分军事设施，分析者认为伊斯兰革命卫队并不因此弱化，反而可能在危机中抬升；除非出现更大不稳定性，否则长期缺乏统一可信的反对力量（包括在海外的Reza Pahlavi动员）仍会限制政权更替空间。

Iran’s Islamic Republic has lasted nearly half a century despite invasions, internal revolts, and repeated attacks on its leadership, mainly because it was built as a deliberately fragmented structure. Power is distributed among the president, the clerical establishment, and the Revolutionary Guard, but all operate under the authority of Supreme Leader Ali Khamenei. This institutional design has turned fragmentation into durability: under prolonged pressure, the system has repeatedly adapted rather than collapsed, combining coercion, managed political opening, and elite bargaining to sustain continuity.

Khamenei, 86, has ruled for almost four decades after succeeding Ayatollah Ruhollah Khomeini in 1989, and now occupies extraordinary authority across major state levers, including commander of the armed forces and control of judicial and institutional appointments such as the Guardian Council, which screens all public candidates. This year’s unrest, the deadliest and most violent since 1979, was contained through a crackdown that killed thousands. Even after the 2023–2026 regional shock after October 7 disrupted his proxy network and killed key military advisers, the leadership frame of “strategic patience” persisted: combine external resistance with internal pressure management.

Reformists have weakened sharply over the last decade. They can participate, but only within strict red lines that protect the clerical core and Khamenei’s primacy. Masoud Pezeshkian, the first reformist president in two decades, is widely viewed as a managed concession and loyalty signal rather than a system-level reset. Hardliners, embodied by figures like Mohammad Bagher Ghalibaf and the Revolutionary Guard, have continued consolidating control over economy, nuclear policy, and regional armed networks in Lebanon, Syria, Iraq, and Yemen. Even if U.S. strikes damage military sites, the regime’s structure may protect or even strengthen the Guard; meanwhile a fragmented opposition, including exiled Reza Pahlavi, remains too disunited to convert unrest into a credible transfer of power.
