Are we still at war with Iran?

What is the current status of the 2026 Iran war?

As of late June 2026, the conflict that began on February 28 has moved from open combat to a ceasefire. The Encyclopaedia Britannica (reference work) notes that a fragile ceasefire was already in place by March, but significant hostilities continued through April and into May. On June 14, the Institute for the Study of War (security think tank) reported that the United States and Iran had reached an agreement calling for a ceasefire on all fronts and reopening of the Strait of Hormuz. The AP News (wire service) confirmed on June 18 that President Donald Trump finalized a pact that would reduce Iran’s stockpile of highly enriched uranium and suspend U.S. sanctions.

Are US and Israeli forces still engaged?

The U.S.-Israeli military campaign, code-named Operation Epic Fury, concluded on May 5, 2026, according to Encyclopaedia Britannica. However, the ceasefire agreement did not require a full withdrawal of forces, and both American and Israeli assets remain deployed in the region. The CNBC (business news) report on the June 22 roadmap states that deconfliction mechanisms are part of the plan, indicating that military presence continues.

Bottom line: The ceasefire is conditional, and any violation could trigger renewed conflict.

Is it true that Iran and Israel are at war?

History of Iran–Israel conflict

Iran and Israel have been locked in a proxy conflict for decades, with Iran supporting Hezbollah and other groups opposed to Israel. But the February 28, 2026 airstrikes marked the first direct military engagement between Israeli forces and Iran. The Encyclopaedia Britannica describes the 2026 Iran war as an open conflict that includes Israel as a primary belligerent alongside the United States.

Direct military engagement since February 2026

Israel participated in Operation Epic Fury from day one, conducting airstrikes alongside U.S. forces. The Encyclopaedia Britannica states that the campaign was a joint U.S.-Israeli effort. The University of Oxford confirms that Iran’s counterstrikes targeted not only U.S. assets but also infrastructure in Gulf states that host Israeli diplomatic or military presence. So yes — Iran and Israel are at war, though the current ceasefire holds for now.

Bottom line: The direct engagement is real, but the ceasefire pauses open combat without altering the deeper confrontation.

Who started the war in Iran 2026?

US and Israeli preemptive strikes

The war began on February 28, 2026, when the United States and Israel launched a coordinated air campaign against Iran. The University of Oxford describes this as the start of the 2026 Iran war. The offensive was code-named Operation Epic Fury by the U.S. military, per Encyclopaedia Britannica. In response, Iran immediately struck U.S. bases and allied cities across the Gulf.

Iran’s nuclear program as a casus belli

The stated rationale for the attack was Iran’s nuclear enrichment activities and its threats to Israel. Diplomatic efforts had broken down in early 2026. The AP News reported that the June ceasefire deal directly addresses Iran’s stockpile of highly enriched uranium, confirming that the nuclear issue was central to the conflict.

Bottom line: The first shots were fired by the U.S.-Israel coalition, but the pre-war nuclear and proxy activities gave the stated reasons for the attack.

Why is the US at war with Iran?

Nuclear negotiations breakdown

By early 2026, efforts to revive the 2015 nuclear deal (JCPOA) had collapsed. Iran had accelerated enrichment to near-weapons-grade levels, and the U.S. administration concluded that diplomacy was no longer containing the program. The AP News report on the June 18 deal mentions that the pact specifically aims to reduce Iran’s enriched uranium stockpile, underscoring that the nuclear standoff was the primary driver.

Iran’s support for proxies

Washington also cited Iran’s arming and funding of the Axis of Resistance — including Hezbollah, Hamas, and Houthi rebels — as a reason for military action. The Institute for the Study of War (ISW) reported in April 2026 that Iran’s negotiation proposals demanded an end to the war on Tehran’s terms, including guarantees for its proxy networks. This suggests that proxy support was a core issue.

Strategic interests in the Middle East

The Strait of Hormuz blockade, which Iran imposed early in the conflict, disrupted global oil shipments and gave Washington a strong economic incentive to act. The CNBC roadmap explicitly includes reopening the strait without tolls, confirming that energy security was a key U.S. concern.

Who is winning the Iran war?

Military assessments by CSIS

Encyclopaedia Britannica notes that the U.S.-Israeli campaign achieved its main objectives by May 5, 2026, but the conflict expanded regionally. The Institute for the Study of War (ISW) assessed in June that the U.S. and Israel had dealt severe blows to Iran’s leadership and military infrastructure. However, the same ISW report highlights that Iran was able to negotiate a ceasefire that preserved its political regime and allowed it to reopen oil exports — a partial strategic win for Tehran.

Civilian casualties and infrastructure damage

Exact casualty figures remain unclear. The University of Oxford commentary describes missile strikes on civilian areas in multiple Gulf capitals, indicating significant non-combatant impact. Both sides have suffered infrastructure losses, but detailed numbers are not yet publicly available from independent sources.

Regional escalation

The war drew in Iran’s allies across Lebanon, Yemen, and Iraq, broadening the theatre. The ISW April 28 update notes that Iran’s three-stage proposal included terms for deconfliction in Lebanon, suggesting that the conflict had spread dangerously. By June, the ceasefire had paused the fighting, but the underlying regional tensions remain.

When will the Iran war end?

Negotiation prospects

The June 22 roadmap, as CNBC reported, sets a 60-day timeline for final negotiations. AP News adds that the deal includes a suspension of U.S. sanctions and a reduction of Iran’s enriched uranium stockpile. If these talks succeed, a formal end to the war could come by late August 2026. However, ISW cautioned in April that Iran’s previous proposals offered no concessions, raising doubts about its willingness to compromise.

Factors influencing duration

The key variables are the Strait of Hormuz blockade, Iran’s nuclear ambitions, and U.S. domestic politics. The CNBC roadmap includes a toll-free reopening for at least 60 days, but a permanent solution requires a broader deal. AP News notes that U.N. sanctions relief is not yet settled, which could become a sticking point.

Expert predictions

A University of Oxford expert commentary described the war as “the most dangerous Gulf conflict in decades” and suggested that even with a ceasefire, the risk of renewed fighting remains high. ISW concludes that the ceasefire is fragile and that without a comprehensive nuclear agreement, the war could resume within months.

Expert perspectives

The war represents the most direct confrontation between Iran and the United States since the 1979 revolution. Even with a ceasefire, the underlying drivers remain unresolved.

— Analysis from the University of Oxford (academic analysis)

Iran’s April proposal offered no concessions and was clearly designed to end the war on Tehran’s terms. The June ceasefire was a pragmatic shift after sustained military pressure.

— Institute for the Study of War (security think tank)

The agreement allows Iran to freely export oil again, which changes the economic calculus for the entire region. But the nuclear question is only postponed, not solved.

— AP News (wire service)

Opening the Strait of Hormuz without tolls for at least 60 days is a significant concession from Iran, but it buys time for broader talks. The real test is whether both sides can negotiate a permanent settlement.

— CNBC (business news)

The war has reshaped the Middle East in just four months. For the international community, the choice is clear: support the fragile 60-day roadmap, or prepare for a wider conflict that could choke global oil supplies and draw in more players. The fate of the ceasefire — and the region — now hinges on whether both Washington and Tehran can turn a truce into a lasting deal.

For readers wondering about the broader implications, a detailed global war risks analysis contextualizes the 2026 Iran conflict within wider global tensions and potential scenarios.
