For decades, the relationship between the United States and Iran has been characterized by mistrust, proxy conflicts, and diplomatic deadlocks. However, the events of the last few years—and specifically the last 24 hours—have pushed this historic rivalry into uncharted and highly volatile territory.
Following months of soaring tensions, stalled negotiations, and internal unrest within Iran, the United States and Israel launched massive, coordinated military strikes against Iran on February 28, 2026. With Iranian state television officially confirming the death of 86-year-old Supreme Leader Ayatollah Ali Khamenei in a sombre 5:00 a.m. broadcast on March 1 and declaring 40 days of national mourning, the Middle East is facing an unprecedented paradigm shift.
Here is a comprehensive breakdown of how we got here, the current state of the conflict, and what it means for the world.
The Road to Ruin: From the JCPOA to the 12-Day War
The modern animosity between Washington and Tehran spans over four decades, but the current escalation traces its roots to the collapse of the 2015 Iran nuclear deal (JCPOA). Following the U.S. withdrawal from the agreement in 2018 during Donald Trump’s first presidential term, the U.S. implemented a “maximum pressure” sanctions campaign. In response, Iran incrementally expanded its enriched uranium stockpiles and curtailed international inspections.
Diplomatic efforts briefly flickered back to life in early 2025. U.S. Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi engaged in indirect, Omani-mediated talks aimed at reaching a new nuclear agreement. President Trump set a 60-day deadline for Tehran to agree to terms that included a permanent end to uranium enrichment and a halt to support for regional proxy groups.
When the deadline passed without a breakthrough, Israel and the U.S. initiated what became known as the “12-Day War” (June 13–24, 2025). Sparked by Israel’s Operation Rising Lion, the precision strikes devastated Iranian nuclear infrastructure—including the Natanz facility—and assassinated top military commanders, such as IRGC Chief Gen. Hossein Salami and Armed Forces Chief Maj. Gen. Mohammad Bagheri. Iran retaliated with an unprecedented barrage of nearly 900 ballistic missiles and 1,000 armed drones.
While the conflict officially ended in a U.S. and Qatari-mediated ceasefire on June 24, it served as a brutal turning point. The war deeply humiliated the Iranian regime, exposing glaring vulnerabilities in its air defense networks and shattering any remaining illusions of a peaceful diplomatic off-ramp.
Internal Collapse: The Iranian Protests of 2025–2026
As external pressure mounted in the aftermath of the 12-Day War, Iran began to fracture from within. By late December 2025, Iran’s economy was in freefall, with the rial plunging against the U.S. dollar and basic living costs soaring. This economic collapse triggered nationwide anti-government protests that quickly escalated into a direct, existential challenge to the Islamic Republic’s clerical rule.
The Iranian government responded with a brutal crackdown, arresting tens of thousands and imposing widespread, weeks-long internet blackouts. By January 2026, regime security forces had killed thousands of Iranian protesters in the streets. As the death toll climbed, President Trump openly encouraged the Iranian populace, bypassing diplomatic norms to incite a revolution. He issued statements urging protesters to “take over your government” and assured them that “help is on the way”. He even offered “complete immunity” to members of the paramilitary Islamic Revolutionary Guard Corps (IRGC) if they laid down their arms, warning them they would face “certain death” otherwise.
The February 28 Escalation: “Operation Epic Fury”
Despite a brief resumption of indirect nuclear talks in Geneva and Oman in February 2026, the diplomatic window slammed shut. Fueled by weeks of heavy, behind-the-scenes lobbying from Israeli Prime Minister Benjamin Netanyahu and Saudi Crown Prince Mohammed bin Salman, the U.S. and Israel initiated a massive military campaign against Iran on February 28, 2026, dubbed “Operation Epic Fury” by President Trump.
Unlike the targeted strikes of 2025, this operation was explicitly designed with sweeping objectives, notably executed by the U.S. without seeking congressional approval. President Trump stated that the U.S.-led operation sought to completely eliminate Iran’s nuclear and missile programs, annihilate its navy, and effectively topple the regime.
Key developments of the February 28–March 1 strikes include:
- Decapitation Strikes: Israel and the U.S. deliberately targeted the entire upper echelon of Iranian leadership. Munitions leveled Khamenei’s compound in Tehran, and his body was reportedly pulled from the rubble. State media outlets later confirmed that several members of Khamenei’s family, including his daughter and granddaughter, were also killed. Prime Minister Netanyahu announced, “There are many signs that this tyrant is no longer,” while Trump took to Truth Social to call Khamenei “one of the most evil people in History”.
- Military Infrastructure: The Israel Defense Forces (IDF) and U.S. Air Force targeted hundreds of military sites. The focus was heavily on government ministries, defense and intelligence headquarters in Tehran, missile launchers in western Iran, and naval assets like the IRGC frigate Jamaran to blunt Tehran’s retaliatory capabilities.
- Call for Regime Change: In a video address announcing the commencement of major combat operations, President Trump directly called on the Iranian people to overthrow the government, telling them: “When we are finished, take over your government. It will be yours to take. This will be probably your only chance for generations”.
- Iran’s Retaliation: Tehran responded almost immediately. The Iranian Red Crescent reported over 200 casualties and 700 injured in the initial waves of strikes. In response, Iran launched waves of ballistic missiles (including Emad and Ghadr missiles) at Israel, and targeted U.S. military facilities across the Persian Gulf, including bases in Bahrain, Iraq, Saudi Arabia, Qatar, and the UAE.
What Happens Next?
As of March 1, 2026, the situation remains incredibly fluid and dangerous. The U.S. and Israeli strategy relies heavily on the hope that the decapitation of Iran’s leadership will empower the ongoing domestic uprising to successfully overthrow the Islamic Republic.
However, regime change from thousands of miles away is a high-risk gamble. The immediate questions facing the international community are profound:
- Will the Iranian Regime Collapse? With the confirmed death of the 86-year-old Khamenei, a massive power vacuum has opened. Khamenei reportedly had a shortlist of successors, heavily rumored to include his son. It remains to be seen if the IRGC will double down on violently suppressing the protests or if the regime will fracture from within. Figures like Reza Pahlavi, son of the overthrown Shah, have already publicly declared that the Islamic Republic has “effectively come to an end”.
- Regional War: Iran’s heavily armed Axis of Resistance—including Hezbollah in Lebanon, the Houthis in Yemen, and militias in Iraq and Syria—is likely to activate fully. The security environment has deteriorated so rapidly that U.S. Secretary of State Marco Rubio abruptly canceled a planned trip to Israel.
- Global Economic & Travel Impact: With missiles flying across the Persian Gulf—a vital artery for global energy supplies—global markets and oil prices are bracing for severe shocks. Commercial aviation has been paralyzed; aviation regulators worldwide, such as India’s DGCA, have issued urgent advisories ordering airlines to avoid the airspace of 11 Middle Eastern countries, effectively turning the region into a no-fly zone.
Conclusion
The USA vs. Iran conflict has evolved from a shadow war of proxy battles and cyberattacks into a direct, existential military confrontation. The strikes of February 2026 mark the definitive end of an era of diplomacy and the violent beginning of a new, unpredictable chapter in the Middle East. Whether this leads to the birth of a new Iran or a devastating regional war is a question that will be answered in the critical days and weeks to come.
