US-Israel War with Iran Enters Two-Week Ceasefire After 39 Days of Intense Conflict
A little over five weeks after it erupted, the United States-Israel war with Iran has entered a temporary pause, with a two-week ceasefire announced by US President Donald Trump. The conflict, which escalated rapidly into a wider regional war, resulted in thousands of deaths, displaced hundreds of thousands of people, and severely disrupted global energy markets, causing significant economic instability worldwide.
Shock and Awe: Decapitation Strike and Immediate Retaliation (February 28 – March 3)
The war began with what analysts termed a "decapitation strike." On February 28, US and Israeli forces launched coordinated attacks across Iran, targeting military and political infrastructure. The strikes killed Supreme Leader Ali Khamenei and senior military officials, using B-2 bombers, fighter jets, and cruise missiles in one of the most complex joint operations in recent years. Civilian casualties mounted quickly, including a deadly strike on a school, later acknowledged by US officials as a targeting error.
Iran's response was immediate and expansive:
- Hundreds of missiles and drones were launched at Israel and US bases across the Gulf.
- Targets included Bahrain, Qatar, Kuwait, Saudi Arabia, and the UAE.
- The Strait of Hormuz, a critical global oil artery, was effectively disrupted, transforming the conflict into a regional war within 48 hours.
On March 1, the war claimed its first American casualties when an Iranian drone strike killed six US soldiers in Kuwait.
Expansion into a Regional War Theatre (March 4 – March 12)
By early March, the conflict had widened significantly:
- Hezbollah opened a northern front from Lebanon.
- Gulf infrastructure and shipping lanes became active targets.
- European powers and regional actors began defensive deployments.
Iran appointed Mojtaba Khamenei as the new supreme leader on March 8, signalling regime continuity despite leadership losses. Simultaneously, attacks began targeting energy infrastructure, with oil depots and refineries hit for the first time. Iran escalated operations around the Strait of Hormuz, striking commercial vessels, leading to a sharp surge in oil prices and forcing global intervention to stabilise markets.
Energy War and Strategic Infrastructure Strikes (March 13 – March 20)
Mid-March marked a decisive escalation into economic warfare. On March 13, the US bombed Kharg Island, which handles a majority of Iran's oil exports, signalling a direct hit on Tehran's economic lifeline. From March 17 to 18, senior Iranian leaders, including Ali Larijani, were killed, and Israel struck the South Pars gas field, core of Iran's gas output. Iran retaliated by hitting Qatar's Ras Laffan LNG hub, shifting the focus from military targets to strategic economic infrastructure and raising fears of prolonged global energy instability.
Multi-Front Escalation: Houthis, Gulf Bases, and Global Spillover (March 21 – March 31)
By late March, the war had expanded further:
- Houthis in Yemen launched missiles at Israel.
- Iranian strikes injured US troops in Saudi Arabia.
- Shipping disruptions intensified in the Strait of Hormuz.
Around March 20–21, the conflict briefly expanded beyond its immediate geography when Iran reportedly launched ballistic missiles towards Diego Garcia, a key US–UK military base in the Indian Ocean. According to Reuters, at least two missiles were fired, with one breaking apart mid-flight and the other intercepted by a US naval air defence system. Simultaneously, diplomacy flickered, as on March 23, Trump acknowledged talks with Iran, the first sign of potential de-escalation. However, this period was also marked by repeated US deadlines and threats, including ultimatums linked to reopening the Strait of Hormuz.
Direct Confrontation and Aerial Losses (April 1 – April 5)
The war entered a more direct and risky phase in April. On April 3, Iran shot down a US F-15E fighter jet, the first such loss in the conflict, triggering a high-risk rescue mission inside Iranian territory. This downing reflected Iran's retained military capability despite weeks of sustained bombardment. At the same time, Trump claimed the US had "largely achieved" its objectives but continued to authorise strikes, reflecting a widening gap between rhetoric and battlefield reality.
Brinkmanship and Ceasefire (April 6 – April 7)
The final days before the ceasefire were marked by extreme brinkmanship. Trump issued multiple deadlines, including a final ultimatum warning that Iran's "whole civilisation" could be destroyed if the Strait of Hormuz was not reopened. Hours before the deadline, US and Israeli forces struck key infrastructure again, including transport networks, while diplomatic pressure intensified, with Pakistan mediating. On April 7, the US and Iran agreed to a two-week ceasefire, with Iran committing to allow safe passage through the Strait of Hormuz. Oil prices fell sharply following the announcement, reflecting immediate market relief.
Shifting Estimates and Rolling Deadlines
Throughout the conflict, US President Donald Trump repeatedly revised both the expected duration of the war and the deadlines issued to Iran, creating a pattern of fluid timelines that became a defining feature. In the opening days, Trump projected a relatively short campaign, telling the media the war could last "four weeks, or less," before adjusting that estimate to "four to five weeks." As operations intensified, he signalled flexibility, saying the campaign would continue for "whatever it takes," and at one point emphasising that wars could be sustained with a "virtually unlimited supply" of US munitions.
As the conflict progressed into April, the projected timeline shifted again. In his first televised address, Trump said the US was on track to achieve its objectives "shortly, very shortly," adding that "over the next two to three weeks, we're going to bring them back to the Stone Ages, where they belong." At other moments, he struck a contradictory note, claiming the war was "pretty much complete" while also insisting that forces needed to "finish the job."
Running parallel to these broad estimates were a series of operational ultimatums tied largely to Iran's actions in and around the Strait of Hormuz. These deadlines were repeatedly set and then extended:
- March 21: Trump issued an initial 48-hour warning linked to Iranian actions in the Gulf.
- March 23: The deadline was pushed back by five days as diplomatic signals emerged.
- March 26: A further extension of 10 days followed amid continued hostilities.
- April 4: A fresh 48-hour ultimatum was announced as tensions peaked again.
- April 7: A final deadline was set hours before the eventual ceasefire announcement.
According to analysts cited by BBC, while it is not unusual for wartime timelines to evolve as battlefield realities change, the frequency and range of revisions in this case stood out, reflecting both the unpredictability of the conflict and the administration's shifting assessment of its trajectory.
Trump's Shifting War Goals
Trump's stated objectives evolved significantly over the course of the war:
- Initial phase (February 28): Called on Iranians to overthrow their government, framing strikes as an opportunity for regime change.
- Early war (March 1–6): Focus shifted to destroying Iran's missile and military capabilities, with a demand for "unconditional surrender."
- Mid-war (March 8–15): Contradictory claims emerged, with Trump stating the war was "just beginning" versus "pretty much complete," and softening his stance on regime change.
- Late war (March end–April): Emphasis shifted to nearing objectives, focusing on reopening the Strait of Hormuz and stabilising the region.
The Broader Picture
The 39-day conflict marks the second time in under a year that Trump directly engaged US forces in a war involving Tehran. While the administration has framed the ceasefire as a success, the shifting objectives, timelines, and evolving battlefield dynamics highlight the complexity of the campaign. The conflict had far-reaching consequences:
- Over 3,000 deaths reported, largely in Iran and Lebanon.
- Millions displaced across the region.
- Global oil and shipping disruptions.
- Expansion into Lebanon and Red Sea theatres.
The war has deepened geopolitical divides, with domestic political backlash in the US and increased tensions across allied nations. The long-term outcomes, both in Iran and across the region, remain uncertain, even as the guns fall temporarily silent.
What Next?
The ceasefire remains fragile, with key issues, including Iran's military capabilities, regional influence, and nuclear programme, unresolved. While Trump has framed the pause as a strategic success, the war's shifting objectives, inconsistent timelines, and widening scope suggest that its long-term consequences are still unfolding. As history has shown, from Vietnam to Iraq, wars rarely end on the timelines set at their outset, leaving the future of this conflict and its regional impact in a state of flux.
