Since February 28, at least 4,564 people have been wounded in Israel by Iranian missile strikes, according to Israel's Ministry of Health. Fourteen have been killed directly. The Dimona and Arad strikes on Saturday — which injured 180 people near Israel's nuclear research facility — penetrated Israeli air defenses at two locations simultaneously. Iran has fired 400 missiles at Israel. The Israeli Air Force claims a 92% interception rate. The 8% that got through have killed people, destroyed buildings, and raised a question that defense analysts are now addressing openly: did Israel underestimate Iranian military capabilities?
The Scale of Iran's Arsenal
Defense analysts describe Iran's missile program as the Middle East's largest and most varied. It was developed over decades specifically because Iran lacks a modern air force — missiles are the country's primary means of projecting force beyond its borders.
The arsenal includes multiple tiers, each designed for different operational purposes:
The critical detail: Former Iranian Supreme Leader Ali Khamenei had previously limited Iran's missile range to 2,200km. He removed that cap after Israel's 12-day war on Iran in June 2025. That decision — made months before the current war — means Iran entered this conflict with its missile program unconstrained for the first time in its history.
Why the Israeli Public Hasn't Felt War Like This Before
Al Jazeera's analysis identifies a structural point that is worth stating clearly: Israel has regularly waged military campaigns in Gaza, the West Bank, Lebanon, and Syria. In all of those campaigns, the opponents used rudimentary rockets — unguided projectiles with limited range and minimal payload. Iron Dome was designed to intercept those rockets and has done so with high success rates.
Iran is a categorically different adversary. Its missiles are guided, carry warheads weighing hundreds of kilograms, and can be fitted with cluster munitions that disperse 20–80 bomblets per missile. Intercepting the delivery vehicle does not stop the bomblets already released.
The result: even with a 92% interception rate, the 8% that penetrates delivers significant destructive force. The 4,564 wounded figure — which represents casualties across multiple cities over 23 days — is unprecedented in Israeli modern military history for a state-on-state conflict.
The Dimona Question
Saturday's strikes near Dimona are the most strategically significant because of what sits 13km away: the Shimon Peres Negev Nuclear Research Center — Israel's undeclared nuclear weapons facility.
Israeli firefighters confirmed that "interceptors were launched that failed to hit the threats, resulting in two direct hits by ballistic missiles with warheads weighing hundreds of kilograms" at both Arad and Dimona simultaneously. This dual failure — two locations, same time — suggests either saturation (Iran fired enough missiles to overwhelm local batteries) or a trajectory/speed profile that defeated the interception systems.
Hundreds of people have been evacuated from both strategic towns. Netanyahu described it as a "very difficult evening in the battle for our future." The IAEA confirmed no radiation release at the nuclear facility — the missiles hit civilian areas in the towns, not the facility itself. But the proximity is the point: Iran demonstrated it can land warheads within 13km of Israel's most sensitive installation.
The June 2025 War: The Precedent Nobody Talks About
The current war is not the first US-Israeli military operation against Iran. In June 2025, Israel launched a 12-day war on Iran that included strikes on Iran's three main nuclear facilities. The US joined for one day of strikes. The IAEA says that 12-day war did more damage to Iran's nuclear program than the current 23-day war has.
But the June war also taught Iran specific lessons:
- Khamenei removed the 2,200km missile range cap afterward — explicitly enabling longer-range systems
- Iran reportedly used cluster munitions for the first time during the June war (Amnesty International condemned this)
- Iran hardened and dispersed its nuclear materials between June and February — making the current strikes less effective (per IAEA's Grossi)
- Israeli air defense vulnerabilities exposed in June were not fully addressed before the current war began
The pattern: Israel struck Iran. Iran adapted. Israel struck again. Iran was more prepared. The current war's results — "relatively marginal" nuclear damage (IAEA), 4,564 wounded Israelis, air defense failures near the nuclear facility — reflect an adversary that learned from the first round.
The Miscalculation Question
Whether Israel "miscalculated" depends on what it expected. If the expectation was that air strikes would degrade Iran's nuclear program to the point of elimination — the IAEA says that hasn't happened. If the expectation was that Iranian retaliation would be limited and manageable — 4,564 wounded and air defense failures at Dimona suggest it was more than expected. If the expectation was a short operation — Netanyahu's own statement about a "very difficult evening" and the IDF's description of Lebanon operations as "prolonged" suggest the timeline has expanded beyond original planning.
What is not in dispute: Israel entered this war with the most sophisticated layered missile defense system in the world — Iron Dome, David's Sling, and Arrow-3. That system is performing at a claimed 92% interception rate. And it is not enough to prevent significant casualties and strategic strikes near nuclear infrastructure.
Iran's missile program was built specifically for this scenario — decades of investment in guided missiles precisely because Iran cannot compete with Israeli and American air power. The war is testing whether investment in offense (Iran) or defense (Israel) produces better outcomes when both are operating at full capacity. Twenty-three days in, the answer is not cleanly in either side's favor.
4,564 wounded in 23 days. 92% isn't 100%. The 8% matters.
