## Answers

### Answer by Ravi Vishwakarma

The [United States](https://www.google.com/search?kgmid=/m/09c7w0&q=Why+did+the+U.S.+and+Israel+attack+Iran,+and+what+sparked+the+escalation?) and [Israel](https://www.google.com/search?kgmid=/m/03spz&q=Why+did+the+U.S.+and+Israel+attack+Iran,+and+what+sparked+the+escalation?) launched a joint military operation against [Iran](https://www.google.com/search?kgmid=/m/03shp&q=Why+did+the+U.S.+and+Israel+attack+Iran,+and+what+sparked+the+escalation?) on **February 28, 2026**, citing a combination of nuclear [security concerns](https://answers.mindstick.com/qa/101717/how-does-india-address-national-security-concerns), proxy threats, and a goal of leadership change.

## Stated Reasons for the Attack

U.S. President Donald Trump and Israeli Prime Minister [Benjamin Netanyahu](https://yourviews.mindstick.com/view/60539/why-benjamin-netanyahu-will-not-resign) identified several key objectives for the offensive, codenamed **Operation Epic Fury** (U.S.) and **Operation Roaring Lion** (Israel):

- **[Nuclear Non-Proliferation](https://answers.mindstick.com/qa/101009/what-does-the-nuclear-non-proliferation-treaty-npt-aim-for)**: The U.S. and Israel claimed Iran had restarted its nuclear weapons programme, with the IAEA flagging uranium enrichment as a matter of "serious concern".
- **Neutralizing Missile Threats**: The allies aimed to destroy Iran's long-range [ballistic missile](https://answers.mindstick.com/qa/34636/which-country-has-successfully-test-fired-naval-strike-ballistic-missile-hormuz-2) capabilities, which they alleged could eventually reach the U.S. mainland.
- **Eliminating Proxy Groups**: The operation targeted Iran's support for regional militant groups, specifically citing the role of Hamas in the October 7, 2023, attacks.
- **Regime Change**: Both leaders explicitly called for the Iranian people to "take over" their government, framing the strikes as an opportunity to topple the existing leadership.

## Factors Sparking the Escalation

Several immediate events in early 2026 served as the catalyst for the conflict: [6]

- **Collapse of Nuclear Talks**: Indirect negotiations mediated by Oman in early February 2026 failed to reach an agreement. While Oman reported a "breakthrough" on February 27, U.S. envoys claimed Iran was still insisting on its right to enrich uranium, leading the U.S. to conclude that diplomacy had been exhausted.
- **Imminent Threat Claims**: The [Trump administration](https://yourviews.mindstick.com/view/81430/why-trump-administration-is-against-aca-in-supreme-court) stated the strikes were "pre-emptive," based on intelligence suggesting Iran was planning an imminent attack on U.S. assets or Israel.
- **Domestic Unrest in Iran**: A deadly crackdown by Iranian security forces on anti-government protesters in January 2026, which reportedly killed thousands, led to increased U.S. threats of military intervention.
- **Regional Pressure**: Reports indicate that the Israeli government and Saudi Crown Prince Mohammed bin Salman repeatedly lobbied the Trump administration to take immediate military action to prevent Iran from growing stronger.

## Immediate Consequences

- **Leadership Casualties**: Initial strikes on Tehran killed Iran's Supreme Leader, **Ayatollah Ali Khamenei**, and several other senior military and government officials.
- **Regional Retaliation**: Iran responded by launching over 170 [ballistic missiles](https://answers.mindstick.com/qa/99129/why-did-north-korea-fire-two-ballistic-missiles-toward-the-east-sea) at Israel and U.S. military bases in Bahrain, Kuwait, Qatar, Jordan, and the UAE.
- **Economic Impact**: Iran announced the closure of the **[Strait of Hormuz](https://yourviews.mindstick.com/view/88520/donald-trump-sends-warships-to-break-iran-s-strait-of-hormuz-blockade)**, a critical chokepoint for 20% of global oil and gas, causing immediate spikes in global energy prices.
