Why Iran is failing to defend itself as the supreme leader succession hits a wall

Why Iran is failing to defend itself as the supreme leader succession hits a wall

The myth of the Iranian "fortress" just evaporated. In the early hours of February 28, 2026, a combined U.S. and Israeli strike force didn't just rattle the windows in Tehran; they essentially dismantled the regime’s ability to see or hit back. For years, we’ve heard about the S-300 batteries and the "Axis of Resistance" deterrence. But when the Tomahawks and F-35s actually showed up, the response was more of a whimper than a roar.

U.S. officials are now being blunt. Iran can barely defend its own airspace. While Tehran managed to lob a few hundred missiles toward Israel and regional bases in a frantic retaliatory "opening salvo," the success rate was abysmal. Interception rates in places like the UAE and Qatar have topped 90%. If you’re the Islamic Revolutionary Guard Corps (IRGC), those aren't just bad numbers. They’re a death sentence for your strategic relevance.

This isn't just about broken hardware. The strikes did something far more permanent: they decapitated the leadership at the worst possible moment. Supreme Leader Ali Khamenei is dead. His defense minister is dead. The head of the IRGC is dead. Now, the people left behind are fighting over the crown while the house is literally on fire.

The air defense illusion falls apart

We've been told for a decade that Iran’s multi-layered defense was a "no-go" zone for Western jets. That was a lie. Or at least, it’s a lie now. The Israeli Air Force reportedly flew 200 jets over Western Iran with near-total impunity. They weren't just dodging missiles; they were hunting them.

The U.S. and Israel used a "decapitation first" strategy that targeted the command-and-control hubs before the first Iranian radar could even warm up. When you take out the brain, the arms just flail.

  • The Russian factor failed: Even the new "Verba" MANPADS and the few Mi-28 helicopters Russia scrambled to send earlier this year did nothing against high-altitude B-2 bombers.
  • TEL hunting is real: Unlike the failures of the Gulf War, 2026 tech—specifically MQ-9 Reapers loitering over Tehran—has made it impossible for Iran to hide its mobile missile launchers (TELs).
  • The numbers are staggering: The Israeli Air Force claims to have destroyed over 300 launchers in the first week.

If you're sitting in the Pentagon, the assessment is simple. Iran's theater ballistic missile launches dropped by 86% within the first 48 hours of the conflict. They aren't "saving" their missiles for a rainy day. They’re losing them before they can get the caps off.

Succession is stuck in a loop

While the military is failing, the political side is a mess. Usually, the Assembly of Experts—an 88-member group of clerics—is supposed to pick a new Supreme Leader "as soon as possible." But "as soon as possible" doesn't account for your meeting hall being bombed.

The first emergency session in Tehran was cut short when the building itself was struck. They tried to move the meeting to Qom. Then they tried an online session. But the real problem isn't the location; it’s the candidate.

The IRGC is pushing hard for Mojtaba Khamenei, the late leader's son. It’s a move for stability, but it’s blowing up in their faces.

  1. Hereditary rule is a hard sell: The 1979 Revolution was built on overthrowing a monarchy. Turning the Supreme Leader position into a family hand-me-down feels like a betrayal to many old-guard clerics.
  2. Security concerns: Israeli Defense Minister Israel Katz didn't mince words. He stated that whoever is picked next is just the next target on the list.
  3. The Larijani factor: While the IRGC wants Mojtaba, an interim council led by Ali Larijani is trying to keep the lights on. It’s a power struggle happening while the country’s infrastructure is being systematically picked apart.

Honestly, the delay in picking a leader isn't just about "respect for the dead." It’s about fear. No one wants to be the one to put on the robe if it comes with a laser-guided bullseye.

Why the "Axis of Resistance" is silent

For years, the threat was that if you touched Tehran, the region would burn. Hezbollah, the Houthis, and various militias in Iraq were the "insurance policy." That policy just bounced.

Hezbollah is currently being shredded in Lebanon. The IDF has reportedly hit over 320 targets in just the last few days. The Houthis are still firing, but they’re isolated. The "ring of fire" that Iran spent billions to build around Israel has turned into a series of disconnected campfires.

Without a central "brain" in Tehran providing real-time intelligence and satellite data (which the U.S. and Israel have successfully jammed or destroyed), these groups are fighting blind. They’re local nuisances now, not a strategic threat to the existence of the Israeli state.

What actually happens next

If you're watching this unfold, don't expect a sudden democratic uprising to fix everything by Tuesday. The IRGC still has 1.2 million boots on the ground, including the Basij militia. They’re currently using those boots to stomp on any protests in the 31 provinces where people are trying to take advantage of the chaos.

The U.S. goal isn't just "regime change" in the 2003 Iraq sense. It’s "strategic neutering." They’re moving from hitting missile sites to destroying the internal security apparatus—the stuff the regime uses to stay in power.

You should expect the following:

  • Continued Air Supremacy: US Reapers will continue to circle Tehran and Shiraz, providing "targeting as a service" to any assets in the region.
  • The "Venezuela" Scenario: Trump has hinted at a scenario where the mid-level bureaucracy stays, but the top-tier "fanatics" are cleared out.
  • Naval Blockade: The Strait of Hormuz isn't officially closed, but with the Iranian Navy basically at the bottom of the Persian Gulf, the U.S. Fifth Fleet is the only one making the rules now.

The Iranian regime is currently a ghost ship. The crew is fighting over who gets to be captain while the hull is full of holes and the engines are dead. If they don't pick a leader and find a way to stop the bleeding, there won't be a country left to lead.

Stop waiting for a "grand bargain" or a diplomatic reset. That door closed when the first Tomahawk hit the Tehran compound. Now, it’s just a matter of how much of the old guard is left to surrender when the smoke finally clears. You need to keep an eye on the Assembly of Experts' next "online" move; that's where the final collapse will likely be televised.
