Iran retaliated against United States and Israeli strikes on February 28, 2026, by launching missile and drone attacks targeting Israel and United States-allied states in the Gulf region, effectively closing the Strait of Hormuz during the conflict
What's happening
Iran fought two of the world's most powerful armies in this escalating confrontation that began on February 28, 2026.
Where the evidence points
Most of Iran's 1,850+ missiles and 3,700+ drones were successfully intercepted by Israeli, U.S., and allied air defenses. Despite the massive volume of fire, Iranian weapons caused limited military damage to intended targets, though some strikes reached civilian or secondary targets. The primary effect was psychological and political rather than operational.
Key drivers
- Conducting 100 waves of strikes undermines claims that air defenses stopped most weapons; repeated massive attacks imply prior waves failed to achieve military objectives.
Evidence on this has been independently challenged and assessed.
Key questions
▸
Will the Strait of Hormuz closure persist, or will shipping resume within months?
Evidence is contested — competing explanations remain open
Because of the gravity of this event, statements about competing explanations are held to a stricter standard of proof.
Ranks compare these explanations against each other; the parenthetical is how likely each one is on its own.
Weighing the available reporting, these explanations rank by evidence:
Most likely: Shipping resumes within a year through ceasefire deal (possible)
Less likely: Iran keeps strait closed for over a year as negotiating leverage (possible)
Best case for Iran keeps strait closed for over a year as negotiating leverage
For: Iran keeps strait closed for over a year as negotiating leverage
- The Strait of Hormuz is blocked to maritime traffic, initiated by the escalation of the conflict between Iran and the Israel-USA coalition from 28 February 2026 and continuing as of June 2026. Closure persisting through June 2026 directly supports the year-long leverage plan over scenarios requiring reopening within months. 1 source, unnamed sources
- Iran mined the central corridor of the Strait of Hormuz on 28 February 2026 after US and Israeli attacks. Mining the central corridor on 28 February establishes a concrete closure mechanism coinciding with the retaliation strike, directly supporting Iran's intent to maintain leverage through sustained blockade. 1 source, unnamed officials

Challenging evidence
- Iran conducted at least 100 waves of decisive retaliatory strikes against sensitive and strategic American and Israeli targets throughout the region. Conducting 100 waves of strikes undermines claims that air defenses stopped most weapons; repeated massive attacks imply prior waves failed to achieve military objectives. 1 source, editorial
- Iranian fighter pilots are believed to have launched a small number of air strikes during the February-March 2026 war, reportedly including a successful bombing of US Camp Buehring in Kuwait using conventional unguided bombs. A successful Iranian bombing of a U.S. base in Kuwait contradicts the hypothesis that air defenses stopped most Iranian weapons, suggesting at least some attacks penetrated defenses. 1 source, multiple independent
- Iran has launched multiple strikes on the Diego Garcia joint US-UK military base since the start of the US-Israel-Iran war in late February 2026. If Iranian missiles reached Diego Garcia and struck it, air defenses did not stop most incoming weapons; successful strikes contradict the intercept-rate hypothesis. 1 source, editorial

Challenging evidence
- Iran conducted strikes against multiple neighboring countries including civilian targets in non-participating states and Oman since February 28, 2026. Striking non-participating civilian states contradicts a narrowly calibrated power-limitation campaign and suggests Iran perceives an existential threat rather than a contained conflict. 1 source, editorial
Less likely: U.S. and Israel aim to overthrow Iran's government (unlikely)
Least likely: Intentions are unclear and may be changing as the conflict unfolds (very unlikely)
Best case for Intentions are unclear and may be changing as the conflict unfolds
For: Intentions are unclear and may be changing as the conflict unfolds
- Iran staged at least 100 waves of retaliatory strikes against sensitive American and Israeli targets across the region after Ayatollah Khamenei's assassination on February 28, 2026. A killing of the supreme leader that triggers 100+ retaliatory waves exemplifies an action-reaction spiral where neither side's original intentions remain static—the assassination itself shifts the conflict's trajectory and forces reactive decisions. 1 source, named source

Most likely: Iran is wildly overstating drone kills (possible)
For: Iran is wildly overstating drone kills
- Since the war began on February 28, 2026, Iran has downed approximately 30 US MQ-9 Reaper drones. Iran's official claim of 30 drones directly substantiates the wildly-overstating hypothesis by providing the very inflated figure critics expect from a state with motive and history of exaggeration. 1 source, editorial

- Iran conducted at least 100 retaliatory strikes against American and Israeli targets following the February 28, 2026 military action. The claim of 100+ retaliatory strikes directly supports this account—such a massive, sustained barrage makes Iran's 30-drone claim mechanically plausible where overstatement would be less likely. 1 source, unnamed sources

- Iran staged at least 100 waves of retaliatory strikes against sensitive American and Israeli targets across the region after Ayatollah Khamenei's assassination on February 28, 2026. The scale of sustained attacks (100+ waves) makes a 10-20 drone loss range plausible without requiring Iran's full 30-claim to be true, settling the middle ground between wild exaggeration and accuracy. 1 source, named source

- Iran closed the Strait of Hormuz to nearly all shipping in response to the US-Israel military campaign launched on 28 February 2026. Iran demonstrably closed the strait to nearly all shipping in response to February 28 strikes—the exact condition this hypothesis requires for an oil crisis. 1 source, multiple independent
- Iran responded by attacking Israel and United States-allied states in the Gulf and effectively closed the Strait of Hormuz. Iran's attack and effective strait closure match the blockade premise underlying the price-doubling scenario. 1 source, multiple independent
- Iran attacked regional energy infrastructure and nearly closed the Strait of Hormuz. Energy infrastructure damage and near-total strait closure directly support the conditions for an oil-price crisis. 1 source, unnamed sources
- The Strait of Hormuz is blocked to maritime traffic, initiated by the escalation of the conflict between Iran and the Israel-USA coalition from 28 February 2026 and continuing as of June 2026. Strait blockade confirmed as continuing through June 2026 matches the sustained closure this hypothesis requires for a genuine supply shock. 1 source, unnamed sources

- Iran conducted retaliatory attacks on Israel that resulted in halting most shipping traffic through the Strait of Hormuz. Iran halted most shipping, contradicting the Navy-clears-strait scenario that requires allied navies to gradually reopen lanes. 1 source, multiple independent
- Iran closed the Strait of Hormuz to nearly all shipping in response to the US-Israel military campaign launched on 28 February 2026. Iran's demonstrated closure to nearly all shipping conflicts with the hypothesis that navies can rapidly restore meaningful traffic flow. 1 source, multiple independent
- Iran responded by attacking Israel and United States-allied states in the Gulf and effectively closed the Strait of Hormuz. Iran's effective closure stands against the hypothesis that allied navies will overcome Iranian resistance and reopen lanes. 1 source, multiple independent
- Iran attacked regional energy infrastructure and nearly closed the Strait of Hormuz. Near-total strait closure and infrastructure damage conflict with the Navy-clearing scenario's assumption of rapid lane reopening. 1 source, unnamed sources
- The Strait of Hormuz is blocked to maritime traffic, initiated by the escalation of the conflict between Iran and the Israel-USA coalition from 28 February 2026 and continuing as of June 2026. Blockade persisting into June 2026 directly contradicts the hypothesis that navies clear the strait and prevent prolonged closure. 1 source, unnamed sources
Least likely: Partial blockade persists: steady high energy costs (very unlikely)
Best case for Partial blockade persists: steady high energy costs

For: Partial blockade persists: steady high energy costs
- Iran conducted retaliatory attacks on Israel that resulted in halting most shipping traffic through the Strait of Hormuz. Iran halting most shipping through retaliatory attacks matches the partial-blockade scenario where Iranian forces degrade but aren't fully overcome. 1 source, multiple independent
- Iran closed the Strait of Hormuz to nearly all shipping in response to the US-Israel military campaign launched on 28 February 2026. Iran's near-total strait closure aligns with the partial-blockade hypothesis that Iran maintains enough capability to prevent normal traffic. 1 source, multiple independent
- Iran retaliated against the 28 February 2026 strikes with missile and drone attacks targeting Israel and United States allies in the Gulf region. Retaliatory missile and drone attacks confirm Iran's military capability to maintain blockade pressure as the partial-blockade scenario posits. 1 source, multiple independent
- Iran responded by attacking Israel and United States-allied states in the Gulf and effectively closed the Strait of Hormuz. Iran's effective strait closure and attacks match the partial-blockade hypothesis where Iranian forces persist despite allied opposition. 1 source, multiple independent
- Iran responded to the February 28, 2026 bombing with missile and drone attacks against Israel and across the region. Iran's sustained attack capability matches the partial-blockade scenario where Iranian forces prevent normal traffic through continued military threat. 1 source, multiple witnesses
