How Successful is US Seems to be after Khamenei’s assassination? A critical review of Iranian Capability & Ground Reality   

The assassination of Iran’s Supreme Leader Ayatollah Ali Khamenei on February 28, 2026, in a joint US-Israeli airstrike has dramatically escalated tensions across the Middle East. While the operation dubbed as ‘Epic Fury’ by US forces and involving CIA intelligence-guided precision strikes, achieved a major tactical success by eliminating the 86-year-old leader alongside other high-ranking officials, it has introduced significant strategic uncertainties for Washington and its allies. This analysis evaluates key claims from circulating narratives about Iran’s military resilience, succession planning, regime stability, and regional repercussions, drawing on verified reporting from sources like CENTCOM, the Institute for the Study of War (ISW), Al Jazeera, Defence Chronicle and others.

Iran’s military capabilities remain substantial despite heavy degradation from ongoing strikes. Pre-conflict estimates placed Iran’s ballistic missile inventory at around 3,000 units, with several hundred capable of long-range strikes. The IRGC Aerospace Force has been a primary target, with US and Israeli forces destroying numerous launchers, storage sites (eg- Imam Ali Missile Base and Bid Ganeh facility), and production elements. Drone assets, including Shahed-series models, have proven resilient in evading some defences and inflicting damage regionally, though manufacturing sites like those in Esfahan have been hit. IRGC personnel numbers hover around 190,000 to 600,000 (including reserves), supported by the Basit paramilitary network for internal security rather than frontline elite operations. Recent CENTCOM statements indicate over 1,250 targets struck in the initial days, including air defences, command centres, and naval assets, significantly blunting coordinated large-scale responses.

Succession mechanisms appear robust and pre-planned. Iran’s constitution provides for an interim leadership council (comprising the president, judiciary head, and a cleric) while the Assembly of Experts selects a new Supreme Leader. Analyst Iman Jalali (US based) has highlighted Iran’s ‘layered contingency plan,’ with multiple backups for key positions and devolved authority enabling regional commanders to act independently. This structure, designed for exactly such decapitation scenarios, suggests continuity under potentially harder-line figures influenced by the IRGC, rather than immediate collapse or moderation. Realising the threat like the present one, Iranian authorities had planned 4+ formula, much in advance. As per this formula, they had named four persons as those taking the charge one after the other in case of assassination of the person, whose substitute is he. This was made for every important key position in the whole government, so we can realise that they would have done the same in case of Khamenei. Only fact is that they are not declaring about who will be Khamenei’s successor, possibly due to threat of him being killed or as part of some larger strategy.    

Regime change via external intervention faces steep hurdles. No credible assessments indicate US plans for a ground invasion requiring hundreds of thousands of troops, an approach echoing past quagmires in Vietnam, Iraq and Afghanistan. Public opinion in the US shows wariness, with polls reflecting disapproval of escalation amid reported casualties. While some analysts note that assassinations can rally loyalists through martyrdom symbolism, evoking vows of revenge from Iranian officials, the response in Iran has been polarized: state-orchestrated mourning contrasts with celebratory protests in some areas and exile communities, reflecting deep societal divisions from prior crackdowns. US had thought that after the elimination of Khamenei, people opposing him and his government will come on streets and will make the IRG very difficult to tackle the situation. They thought that there will be a complete chaos on Iranian streets leading to internal war and weakening of the nation but it doesn’t seem to happen in near future.

Regionally, the strikes risk blowback against US partners. Iran has already launched retaliatory missile and drone barrages across multiple countries, including Gulf states hosting American bases. Hardliners may exploit the event to intensify proxy actions against Saudi Arabia, the UAE, and others perceived as aligned with Washington.

Ultimately, Khamenei’s elimination disrupts command structures and degrades capabilities in the short term, but Iran’s institutional depth, proxy networks, and asymmetric tools ensure prolonged challenges. The operation underscores tactical gains but highlights the limits of airpower alone in achieving lasting strategic shifts without broader political follow-through. As strikes continue, the path forward demands careful calibration to avoid unintended escalation in an already volatile theatre.

          The aim of this study is only to examine the situation and in no way to glorify Iran and its capabilities. I strongly believe that Iran is also our enemy because despite the pact with us for Chabar port, it had always been vocal in support of Islamic forces, which want to destroy India and change the regime here but this is also very important that every Adversary should be well examined on every aspect and we should be aware of what the developments in the middle- east or Iranian region are.
