In the span of a single weekend, the geopolitical architecture of the Middle East was shattered. On February 28, 2026, the United States and Israel launched a sweeping, coordinated assault on Iran — codenamed Operation Roaring Lion by Tel Aviv and Operation Epic Fury by the Pentagon — targeting the country’s top leadership, military command structure, and nuclear infrastructure. The strikes killed Supreme Leader Ali Khamenei, who had ruled Iran for over three decades, along with senior military commanders and members of his family. Iran confirmed his death on March 1 and declared 40 days of mourning. The Islamic Republic, battered but unbroken, has since vowed to fight on — declaring itself “standing against evil.”

What follows is a comprehensive examination of how this conflict erupted, where it stands today, and what it means for the world at large.

How It Came to This: The Road to War

The conflict did not erupt in a vacuum. Since the Hamas attacks of October 7, 2023, and the ensuing Gaza war, Iran-backed proxies across the region — Hezbollah in Lebanon, the Houthis in Yemen, militias in Iraq — had been systematically degraded by Israeli military action. A brief direct Israeli-Iranian exchange of strikes in 2024 was followed by a more significant confrontation in 2025, during which the US launched Operation Midnight Hammer targeting Iran’s nuclear facilities.

By late 2025, massive anti-government protests had erupted inside Iran, driven by economic collapse, a freefall in the rial, and widespread public fury. The Iranian government responded with deadly force; human rights organizations reported massacres of protesters, with the worst violence occurring in January 2026. The regime’s brutality — and its weakened standing — convinced hawks in Washington and Jerusalem that the moment had arrived.

Diplomacy was attempted. The US and Iran held indirect nuclear negotiations in Muscat, Oman in early February, mediated by Omani Foreign Minister Badr Al-Busaidi. A second and third round followed in Geneva. Oman’s foreign minister declared peace “within reach” on February 27, citing new Iranian concessions on uranium stockpiling. But US special envoy Steve Witkoff told a different story: Tehran had insisted on its “inalienable right” to enrich uranium and refused Washington’s demand for zero enrichment. President Trump, who had set a 10-day deadline for a deal, chose war.

Iran Refuses to Negotiate. Strikes Back Hard.

Iran’s response has been ferocious and wide-ranging. Tehran launched retaliatory missile and drone strikes against Israel and against Gulf states hosting US military bases — including the UAE, Qatar, Kuwait, and Saudi Arabia. Civilian infrastructure was not spared; Dubai’s Fairmont The Palm hotel and Dubai International Airport were struck, sending shockwaves through global commerce and tourism.

Iran’s security chief Ali Larijani flatly rejected any resumption of talks with Washington. “We will not negotiate with the United States,” he wrote on X. The Islamic Republic has framed the conflict in existential terms, describing itself as standing against forces of evil — a posture that signals it intends to fight regardless of the military costs.

The assassination of Khamenei has raised urgent questions about succession. He had not publicly designated a successor, and CIA assessments suggest a hardliner from the Islamic Revolutionary Guard Corps (IRGC) is most likely to fill the vacuum. The Islamic Republic, analysts note, remains institutionally intact — its networks and bureaucracies spanning nearly half a century do not dissolve overnight, even under bombardment.

Iran’s Military Arsenal: Missiles, Drones, and a Nuclear Shadow

Iran entered this conflict with a formidable, if asymmetric, military capability. Its war chest includes a vast inventory of ballistic missiles capable of striking targets across the region, as well as swarms of drones that have already been deployed against Gulf infrastructure. The IRGC has demonstrated willingness to target civilian economic infrastructure as a pressure tactic.

Its most consequential leverage, however, is geographic. Iran sits astride the Strait of Hormuz — the 33-kilometer-wide chokepoint through which roughly 20 percent of the world’s daily oil supply flows. An IRGC senior commander declared on Monday that the strait had been shut to all shipping. “If anyone tries to pass, the heroes of the Revolutionary Guards and the regular navy will set those ships ablaze,” warned Ebrahim Jabari, a senior IRGC adviser. Reports indicate that five tankers were damaged and two crew members killed. At least 150 vessels are reported trapped, and major shipping companies including Maersk and Hapag-Lloyd have suspended bookings and rerouted ships around Africa’s Cape of Good Hope — adding 10 to 14 days to transit times.

Pakistan: A Separate Fire on the Fringes

As if the Iran crisis were not enough, a parallel flashpoint has ignited on the Afghan border. Pakistan launched airstrikes on the Bagram Air Base — once the nerve center of America’s two-decade war in Afghanistan, now under Taliban control — in what Islamabad described as a counterterrorism operation. The strikes represent one of the most dramatic escalations in Pakistan-Taliban relations in years, and have prompted serious questions about the motives and judgment of Army Chief Asim Munir. Critics at home and abroad are asking whether Pakistan is deliberately stoking a second front at a moment when the region can least afford additional volatility.

The Hormuz Shock: India’s Energy Crisis

Of all the nations watching the Hormuz crisis with dread, India has perhaps the most to lose in the short term. The numbers are stark: India imports more than 85 percent of its domestic oil needs, and according to S&P Global Commodities at Sea, approximately 52 percent of those imports transit the Strait of Hormuz. As of January 2026, India was sourcing about 2.74 million barrels per day from the Middle East — near its highest level since 2022 — partly because US pressure had forced Indian refiners to cut back on discounted Russian crude.

The consequences of a prolonged closure are potentially severe. Oil Minister Hardeep Singh Puri has publicly stated that India holds about 74 days of crude reserves, but refining industry sources told Reuters the real figure is closer to 20 to 25 days. Analysts at energy consulting firm Rystad Energy warn that even a modest increase in global oil prices will materially damage India’s energy economics, widen the current account deficit, drive inflation, and pressure the rupee.

The crisis is already disrupting Indian exports. Around 400,000 tonnes of basmati rice — 200,000 in transit and 200,000 at Indian ports — are stranded as shipping routes through the Middle East have collapsed. Maersk has suspended new ocean bookings between the Indian subcontinent and the Upper Gulf entirely.

Global Reactions: Divided World, United Alarm

The international response has fractured broadly along familiar geopolitical lines. Western nations have largely, if sometimes cautiously, backed the US-Israeli operation. Canada affirmed Israel’s right to defend itself and supported American efforts to prevent Iran from acquiring nuclear weapons. France urged Iran to respect its international obligations. The United Kingdom has aligned with Washington.

China and Russia have condemned the strikes in unequivocal terms. Russia’s ambassador to the UN called them “an unprovoked act of armed aggression against a sovereign state.” China described the attack as “brazen” and called for the protection of Iran’s sovereignty and territorial integrity. Russia has additionally accused Washington of using nuclear talks as a diplomatic cover while preparing for war.

UN Secretary-General António Guterres addressed the Security Council in somber terms, warning that the conflict carries the risk of “igniting a chain of events that no one can control.” He called on all parties to return to the negotiating table and urged respect for international humanitarian law. EU representatives called for “maximum restraint.” Oman — which mediated talks until the very eve of the strikes — warned the US not to get “sucked in” further to the conflict.

Norway’s Foreign Minister stated that Israel’s initial strike was not consistent with international law, noting that “preventive attacks require an immediately imminent threat.” The legal debate over the constitutional validity of Trump’s decision to strike without congressional authorization is also sharpening at home.

What Comes Next?

The path ahead is deeply uncertain. The US and Israel have spoken repeatedly of “regime change,” but analysts across the political spectrum are skeptical that air power alone can achieve it. Iran’s deeply embedded institutional structures — the IRGC, the clerical establishment, the judiciary, the state media apparatus — have survived for nearly half a century and are unlikely to collapse in days.

Meanwhile, Iran’s survival strategy is clear: impose the highest possible costs on the United States, its Gulf neighbors, and the global economy to create enough pain that external pressure forces a ceasefire and negotiations. The Hormuz closure is the sharpest weapon in that strategy. If sustained, it risks pushing oil prices above $100 per barrel, triggering a global inflation shock and recession pressure across fragile emerging economies.

Trump has indicated openness to future talks, but Iran’s leadership has for now slammed the door. A constitutional process to select a new Supreme Leader is underway — meaning the Islamic Republic is, institutionally speaking, still standing. How long both sides can sustain the economic and human costs of this war, and whether third-party mediators can rebuild a diplomatic off-ramp, will define the coming weeks.

One thing is clear: the world has entered a new and dangerous chapter. The fires burning across the Persian Gulf will not be easily extinguished.
