On February 28, 2026, the United States and Israel launched a massive military operation against Iran. But why? The answer involves decades of tension, failed diplomacy, nuclear ambitions, and a web of regional proxy conflicts that finally reached a breaking point.
The Nuclear Trigger
At the heart of the decision to strike was Iran’s nuclear program. Despite years of international negotiations, sanctions, and the Joint Comprehensive Plan of Action (JCPOA) signed in 2015, Iran had steadily advanced its uranium enrichment capabilities.
By early 2026, Western intelligence agencies concluded that Iran had enriched enough uranium to weapons-grade levels to construct multiple nuclear devices. For Israel, a nuclear-armed Iran represented an existential threat — one that its leadership had repeatedly stated it would not allow to materialize.
The Proxy War Network
Iran’s influence extended far beyond its borders through a sophisticated network of proxy forces:
- Hezbollah in Lebanon — armed with an estimated 150,000 rockets aimed at Israel
- Hamas and Islamic Jihad in Gaza — responsible for the October 2023 attacks
- Houthi rebels in Yemen — disrupting Red Sea shipping since 2023
- Shia militias in Iraq and Syria — regularly targeting US forces
These proxy forces had been increasingly active, creating a multi-front security challenge that both the US and Israel deemed unsustainable.
Failed Diplomacy
The diplomatic track had effectively collapsed. The US withdrawal from the JCPOA under President Trump’s first term in 2018 was never reversed. Subsequent negotiations stalled repeatedly, with both sides accusing the other of bad faith.
By 2025, back-channel communications between Washington and Tehran had broken down entirely. Regional allies like Saudi Arabia and the UAE, once advocates for diplomatic engagement, had shifted toward supporting a more confrontational approach.
The Intelligence Assessment
According to reports, a combination of signals intelligence, satellite imagery, and human intelligence provided what US and Israeli officials described as a “closing window” of opportunity. The assessment indicated that Iran was weeks, not months, from achieving nuclear weapons capability.
The Decision
The joint US-Israeli decision to strike was made at the highest levels. The operation was planned to be swift and decisive — targeting not just nuclear facilities but the entire Iranian military command structure, in an attempt to prevent an effective retaliatory response.
Whether this calculation proves correct remains to be seen, as Iran’s retaliatory strikes against Gulf states and Israeli targets have demonstrated significant remaining military capability.
Historical Context
The 2026 strikes echo several historical precedents: Israel’s 1981 bombing of Iraq’s Osirak reactor, its 2007 strike on Syria’s Al-Kibar facility, and the US assassination of Iranian General Qasem Soleimani in 2020. Each of these operations was justified on similar grounds — the elimination of perceived existential threats before they could materialize.
