The bombs started falling on February 28, 2026. By the time you read this, the United States and Israel have killed Iran’s Supreme Leader Ayatollah Ali Khamenei, launched what the Pentagon calls “Operation Epic Fury” — deploying over 2,000 strikes across 24 of Iran’s 31 provinces — and triggered retaliatory Iranian missile salvos against military bases from Bahrain to Qatar, and civilian infrastructure from Dubai to Riyadh. If you assumed the drumbeats of this war began in late February, you missed the real starting gun. This conflict has been building for four decades, through proxy battles, nuclear negotiations, drone wars, and a June 2025 “12-Day War” that US and Israeli officials described as a warm-up. What is happening right now is not an escalation. It is a culmination.
And yet the question every strategic analyst, central banker, and head of state is trying to answer is not how this started. It is how this ends.
The answer is not simple, and anyone who tells you it is should not be trusted. The Institute for the Study of War, Brookings Institution, Oxford Economics, the Atlantic Council, and Chatham House have all published scenario analyses in the past 72 hours. Their conclusions overlap in one critical place: the next three to four months will determine not just the shape of the Middle East but the trajectory of the global economy, the credibility of the United Nations, and the durability of what experts have called the “multipolar world order” championed by Russia and China. Below are five outcomes that carry the most analytical weight, supported by current data, expert testimony, and observable facts on the ground as of March 5, 2026.
Outcome 1: Accelerated Iranian Regime Collapse and a Post-Khamenei Power Vacuum
The death of Khamenei is not a footnote. It is the central variable. He ruled Iran for 34 years and held ultimate authority over every institution in the country — the Revolutionary Guard Corps (IRGC), the judiciary, the nuclear program, and the military. His death in a US-Israeli airstrike on his compound in Tehran on February 28 removed the one figure capable of imposing strategic coherence on Iran’s response.
Under the Iranian constitution, the Assembly of Experts — an 88-member body, most of whom are conservatives aligned with Khamenei — selects the next Supreme Leader. But Israeli and US airstrikes have already killed the Iranian army chief of staff, the defense minister, and multiple IRGC commanders, according to the UK House of Commons Library briefing published March 5. The CIA had identified several IRGC figures as potential successors to Khamenei, but many of those figures may now be dead or in hiding.
This creates a genuine power vacuum. Israel’s stated war aim is regime change from within. Israeli Prime Minister Benjamin Netanyahu addressed the Iranian people in Farsi, calling on them to “come to the streets, come out in your millions, to finish the job.” That call follows massive domestic unrest that erupted in late December 2025 — protests that spread to over 100 cities across Iran, driven by economic collapse, the devaluation of the Iranian rial, and rising food prices. The US-based Human Rights Activists News Agency estimated the government killed approximately 7,000 protesters by January 2026.
Former Israeli government adviser Daniel Levy told Al Jazeera that Israel’s actual goal is not smooth regime transition but “regime and state collapse.” If that happens — if the IRGC fragments, regional militias lose their command structure, and Iran descends into civil war — the Gulf becomes exponentially more dangerous. There is no institutional infrastructure for a post-Islamic Republic transition. No exile government in waiting. No unified opposition. You would be looking at a failed state scenario with a partially dismantled nuclear program, a contested oil infrastructure, and armed factions competing for control. That is not stability. That is the conditions for a multi-decade crisis.
Outcome 2: A Managed Ceasefire That Leaves Every Core Issue Unresolved
Trump stated publicly that he expects the conflict to last about a month. Oxford Economics, in its initial analysis published March 1, assessed that the conflict “will not last beyond two months.” That timeline aligns with a scenario in which military pressure achieves its immediate tactical objectives — degrading Iran’s air defenses, destroying missile infrastructure, and suppressing the IRGC’s command and control — without achieving regime change.
In this outcome, a ceasefire is brokered, likely through Oman, which has served as the primary backchannel between Washington and Tehran for years. Just hours before Operation Epic Fury began, Oman’s Foreign Minister Badr Albusaidi had met senior US officials and expressed optimism that diplomacy was within reach. His dismay when the bombs fell was palpable and public. The Omani channel remains the most credible path to a negotiated pause.
But a ceasefire leaves every structural problem intact. The February 2026 Geneva talks collapsed over two unbridgeable gaps: Washington’s demand that Iran end all nuclear enrichment activity and the future of Iran’s ballistic missile program. Neither of those issues disappears because the shooting stops. What you get is a frozen conflict — similar in structure to Ukraine after 2014 — where both sides rearm, regroup, and position for the next round. Iran, even if militarily degraded, retains the institutional knowledge and scientific capability to restart its nuclear program within months, not years. The International Atomic Energy Agency confirmed on March 2 that it had “no indication that any of the nuclear installations” had been hit or damaged in the strikes, even as Iran claimed one site was struck.
This outcome is arguably the most likely near-term scenario. It is also the most dangerous in the medium term, because it produces false confidence on all sides.
Outcome 3: A Prolonged Regional War That Pulls in Additional State Actors
On March 4, 2026, Al Jazeera reported explosions across Tehran, Karaj, and Isfahan simultaneously, with IRGC ground forces entering battlefield operations and 230 drones engaged in a single exchange. Iran has struck 27 US military bases across the region, targeted the US Navy’s 5th Fleet headquarters in Bahrain, hit Riyadh and Saudi Arabia’s Eastern Province oil infrastructure, damaged Dubai International Airport, and hit Doha’s Al Udeid air base — where France subsequently deployed an aircraft carrier strike group as of March 4.
That last detail matters. France, a NATO member, now has military assets in the theater. Hezbollah has launched rocket and drone attacks against a military base near Haifa in retaliation for Khamenei’s killing. Lebanon has reported at least 50 dead and 335 wounded from Israeli airstrikes. A NATO interceptor engaged an Iranian missile near Turkish airspace on March 4. Jordan’s armed forces report intercepting 49 drones and ballistic missiles. Kuwait has reported civilian deaths from falling debris. A UNESCO World Heritage Site — Tehran’s Golestan Palace — has been damaged.
This is no longer a bilateral conflict. It is a regional war with the structural conditions for widening. Defense analyst Hamze Attar told Al Jazeera that Iran has been producing ballistic missiles at a rate of 100 per month since the June 2025 conflict, meaning Tehran entered this war with a significant stockpile. Israel’s Iron Dome, David’s Sling, and Arrow systems are already under pressure; interceptor stocks ran low during the 12-day war. Without continuous US resupply, Israel’s air defense capacity will erode.
The scenario where this widens into a full regional war requires one or more of the following: Iran successfully attacking Saudi oil infrastructure at a scale that pulls Riyadh into direct combat; Hezbollah opening a ground front from Lebanon; or Iraq-based Iran-backed militias launching sustained attacks that force a US ground response. All three conditions are currently in play. Rexon Ryu, President of The Asia Group, stated bluntly: “There is substantial immediate risk for regional and potentially global escalation, as Iran may now use any available option to respond.”
Outcome 4: A Severe Global Economic Crisis Without a World War
Even if the shooting stops tomorrow, the economic damage is already significant and accelerating. This is the outcome that most directly affects you, regardless of where you live.
The Strait of Hormuz is functionally closed. An IRGC commander declared it “closed” on March 2, and maritime intelligence firm Windward confirmed that traffic is down at least 80 percent. At least five tankers have been damaged, two crew members killed, and approximately 150 ships are stranded around the strait. The strait handles roughly 20 million barrels of oil per day — about 20 percent of global petroleum supply — as well as 20 percent of the world’s LNG, according to the US Energy Information Administration.
Brent crude has risen 36 percent so far in 2026, reaching $82.76 a barrel by March 4. WTI futures are up 32 percent. Analysts at Capital Economics have warned that if crude oil prices reach $100 per barrel and stay there, that alone could add 0.6 to 0.7 percentage points to global inflation. Former US Treasury Secretary Janet Yellen stated plainly that the conflict “puts the Fed even more on hold, more reluctant to cut rates.” US inflation was already at 2.4 percent in January 2026, above the Federal Reserve’s 2 percent target, compounded further by Trump’s tariff policy.
Anne-Sophie Corbeau, international gas expert at Columbia University, identified the specific LNG vulnerability: “In the LNG world, there is no such thing as spare capacity. So this is absolutely massive. It’s going to impact everybody who is importing LNG.” About 30 percent of Europe’s jet fuel originates from or transits via the Strait of Hormuz. Qatar Airways has grounded all flights. Qatar’s LNG production has been preemptively paused.
Mark Zandi, chief economist at Moody’s, noted that every sustained one-cent increase in the cost of a gallon of gasoline increases US consumer spending on gasoline by nearly $1.4 billion annually. Lower-income households — already under acute financial pressure from prior inflation cycles — absorb the highest proportional impact. The European Central Bank faces what ING economists called a “genuine dilemma,” caught between an oil-driven inflation spike and deteriorating growth under the combined strain of US tariffs and energy disruption.
Oxford Economics assessed that oil, gas, defense stocks, and gold will spike materially and that the global economy faces real volatility in the near term. The Atlantic Council’s Landon Derentz, writing on March 1, argued that the global economy survived crude oil averaging the equivalent of over $100 in today’s dollars during the Iraq War from 2003 to 2011. He urged against hyperventilation. That is a reasonable long-term point. It is cold comfort to the Indonesian government managing rupiah depreciation, to Singapore’s Monetary Authority reassessing its economic projections, or to European households facing a dual energy and trade shock in the same fiscal year.
The economic crisis scenario does not require a world war. It requires the Strait of Hormuz to remain effectively closed for eight to twelve weeks. If that happens, you are looking at recession conditions in multiple import-dependent economies, persistent inflation in the United States and Europe, and a sovereign debt crisis in the most fiscally exposed emerging markets.
Outcome 5: A Reconfigured Middle East Order with China as the Primary Beneficiary
This is the outcome that geopolitical analysts are least willing to say loudly but most willing to document quietly. China purchased more than 80 percent of Iran’s exported oil in 2025, accounting for 13.5 percent of all crude China imported by sea. A weakened Iran — one that can no longer project military power across the region, one whose Axis of Resistance is broken — paradoxically benefits Beijing.
Ahmed Aboudouh of Chatham House noted that Beijing may use the Iran conflict to extract concessions from Washington on issues more directly tied to Chinese interests — Taiwan and trade — in exchange for moderated messaging on Iran’s behalf. Russia, meanwhile, faces a strategic humiliation. As Atlantic Council analysts noted, Khamenei is the third Kremlin-backed autocrat to fall in fifteen months, following Bashar al-Assad in Syria. Moscow described the US-Israeli attack as a “preplanned and unprovoked act of armed aggression,” but its military is overstretched in Ukraine and its capacity to project power into the Middle East is effectively zero. Russia’s own analysts, according to Brookings, did not expect the first strike to be so massive and were caught off guard by the decision to target Khamenei directly.
For Chatham House’s Russia analysts, the war exposes what they describe as the “limits of Russia’s leverage in a fragmenting regional order.” Moscow is not operationally dependent on Iran for its war in Ukraine — but its International North-South Transport Corridor, connecting Russia to Indian markets via the Caspian Sea and Iranian ports, depends entirely on Iranian stability. Israeli and US strikes already targeted the strategic port of Bandar Abbas. If Iran collapses or enters prolonged civil conflict, that corridor collapses with it. Russia loses its primary alternative to Western-controlled maritime trade routes.
The structural beneficiary is China. A post-war Middle East, regardless of which political configuration emerges in Tehran, will need reconstruction capital, infrastructure investment, and a trading partner not aligned with Washington. Beijing is positioned to provide all three. As Chatham House put it, “a weaker Iran will allow greater Chinese influence.” This is not conjecture. It is the logical extension of the Belt and Road Initiative’s existing footprint in the region and China’s existing relationship with Gulf states, Iran, and Iraq.
The reconfigured order scenario does not mean China goes to war. It means China waits, consolidates, and inherits strategic leverage that the United States and Israel will have burned considerable military and economic capital to create.
Are We Heading Toward a World War?
You are right to ask, and the answer requires precision. A world war — defined as a conflict in which major military powers fight each other directly — is not the most probable near-term outcome. Neither Russia nor China has the military capacity or political appetite to enter direct combat against the United States over Iran. Russia’s military is tied down in Ukraine. China’s leadership has consistently prioritized economic relationships over military adventurism. Both have condemned the strikes in the strongest diplomatic language. Neither has moved forces.
What is happening is something structurally different: a war that is geographically, economically, and diplomatically global in its consequences, even if the active combat zone remains concentrated in the Middle East. The closure of the Strait of Hormuz affects Chinese manufacturing, Indian energy costs, European inflation, and American gasoline prices simultaneously. Iranian drone and missile strikes against American military bases in seven countries simultaneously represent the most geographically dispersed military engagement the United States has been involved in since World War II.
David Silbey, a professor of military history at Cornell University, framed the distinction clearly: the June 2025 strikes were targeted at nuclear assets. This conflict is broader, aimed at command and control, leadership, and the military and secret police more generally. Its objectives are not contained. Its duration is not fixed. And its consequences — for global trade, energy security, central bank policy, and the international rules-based order — will outlast the bombs by years.
The International Committee of the Red Cross president Mirjana Spoljaric warned as of February 28 that “a dangerous chain reaction of military escalation was under way across the Middle East with potentially devastating consequences for civilians.” UN Secretary-General António Guterres described the strikes as “squandering” an opportunity for diplomacy. The UN Security Council met in emergency session but passed no resolution.
What happens in the coming months depends not on any single actor but on the interaction of five variables: whether Iran’s government collapses or consolidates, whether the Strait of Hormuz reopens, whether Israel can sustain its military operations without US-funded interceptor resupply, whether domestic political pressure in the United States forces a congressional confrontation with Trump over the lack of authorization for the war, and whether Gulf states absorb Iranian retaliation long enough to maintain regional coherence.
Every one of those variables is genuinely uncertain as of this writing. That uncertainty is itself the defining feature of this moment. You are not watching the beginning of a world war. You may be watching the beginning of a prolonged global disorder — economic, political, and military — that reshapes the international system in ways that experts will spend the next decade trying to understand.
What you do with that knowledge, and what your government, your business, and your community does with it, will matter more than any single airstrike.
