Iran and Israel War: Latest Updates & Key Questions

Few geopolitical conflicts capture the world’s attention quite like the confrontation between Iran and Israel. The latest phase began on February 28, 2026, when the US and Israel launched massive strikes on Iran, citing an imminent nuclear threat, according to the Atlantic Council. This time, a new dimension has emerged: the fight over the Strait of Hormuz. Here’s a look at what’s driving the war, who holds the cards, and what might come next.

Current conflict phase: US-Israel strikes on Iran initiated February 28, 2026 · Previous major outbreak: Twelve-Day War, June 13–24, 2025 · Stated trigger: Alleged imminent nuclear threat from Iran · Diplomatic talks: Mediated UNGA talks between Iran and US/Israel ongoing · Key demand: Iran ties talks to lifting shipping blockades and unfreezing assets

The key facts behind the Iran and Israel war can be broken into a handful of crucial data points — from military timelines to economic choke points.

Why are Iran and Israel fighting?

Historical enmity

The roots of the Iran-Israel conflict stretch back decades. Iran’s 1979 Islamic Revolution ended close ties with Israel, turning the country into a vocal opponent of the Jewish state. Since then, Iran has funded proxy groups like Hezbollah and Hamas, while Israel has repeatedly struck Iranian assets in Syria and elsewhere (BBC News, UK public broadcaster).

Proxy conflicts

For years the two nations waged a shadow war. Israel targeted Iranian nuclear scientists and weapons convoys; Iran armed militias on Israel’s borders. That proxy war turned direct in June 2025, during what became known as the Twelve-Day War, when Israel bombed Iranian military and nuclear sites (BBC News).

Nuclear program dispute

At the core of the fighting lies Iran’s nuclear program. Iran insists it is peaceful, but the US and Israel believe it is seeking a bomb. The 2026 US-Israel strikes were justified as a response to an “imminent nuclear threat,” according to the Atlantic Council (Atlantic Council, Washington-based think tank).

Who started the Iran Israel war 2026?

Sequence of events

• June 2025: Israel strikes Iran in the Twelve-Day War (BBC News).
• February 28, 2026: The US and Israel launch massive strikes on Iran, claiming an imminent nuclear threat (Atlantic Council).
• Iran responds by effectively blocking traffic through the Strait of Hormuz (Atlantic Council).

Claimed triggers

The US and Israel assert that Iran was weeks away from producing a nuclear weapon. Iran denies this and accuses Israel of a preemptive attack. No independent verification of the nuclear threat has been published (NPR, US public radio).

US role

The United States is not a passive ally. It led the bombing campaign alongside Israel. The US reimposed a naval blockade on Iranian ports in July 2026, further restricting Iran’s maritime trade (Reuters, international news agency).

What is the war over between Israel and Iran?

Nuclear threat

Both sides see the nuclear program as existential. Iran views a weapon as a deterrent; Israel sees it as an unacceptable threat. The Atlantic Council notes that the US-Israel strikes were explicitly tied to “imminent nuclear threat” (Atlantic Council).

Regional influence

Iran has built a network of proxies across the Middle East — Hezbollah in Lebanon, militias in Iraq, the Houthis in Yemen. Israel sees this axis of resistance as a direct threat to its security, especially since Iran used these groups to attack Israeli targets during the 2025 war (BBC News).

Economic resources

A new element in the 2026 conflict is the economic dimension. Iran has tied diplomatic progress to lifting shipping blockades and unfreezing its assets. The blocked Strait of Hormuz has become a bargaining chip — and a weapon. Iran’s parliament reviewed a plan to ban US, Israeli, and other “hostile” ships from the strait until Tehran is compensated for war damage (NPR).

Who is stronger, Iran or Israel?

Five dimensions, one pattern: each side holds an advantage in a different domain, but the balance tilts in Israel’s favor militarily and Iran’s favor strategically.

The pattern here is decisive: Israel’s qualitative military edge and American backing give it the battlefield advantage, but Iran’s human capital and geographic position at Hormuz create a strategic stalemate that firepower alone cannot break. The Atlantic Council emphasizes that the blockade alone has already dealt a heavy blow to the maritime order (Atlantic Council).

Why is Iran so important to the world?

Strait of Hormuz

Iran’s location on the Strait of Hormuz gives it outsize influence. A 33 km wide passage, it carries about one-fifth of the world’s oil. Before the war, over 100 vessels passed through daily. By late August 2026, that number had fallen to about five — an almost 95% drop (Al Jazeera, Qatari news network).

Oil and energy markets

The blockade has sent oil prices volatile. CNN reported that just 3,456 vessels crossed the strait in the first 172 days of the war — around 20% of normal traffic (CNN, US news network). Each drop in transit tightens global supply and raises costs for consumers.

Regional stability

Iran also influences conflicts through its proxies. Its support for Hezbollah, Hamas, and the Houthis means that any escalation risks turning into a wider regional war, potentially drawing in Saudi Arabia and the Gulf states (Al Jazeera).

Quotes from the front

The strikes were necessary to neutralize an imminent nuclear threat. Iran was weeks away from a breakout capability.

— Anonymous US official, cited by the Atlantic Council (Atlantic Council)

We will not discuss peace while our ports are blockaded and our assets frozen. Diplomatic progress depends on lifting the siege.

— Iranian diplomat at UNGA, as reported by the Associated Press (Associated Press)

The Iran-Israel war is no longer a regional skirmish — it is a central hinge of the global economy. If the UNGA talks fail, the Strait of Hormuz may remain largely closed, sending oil prices higher and testing the durability of the US-Israel coalition. For world energy markets, the blockades must be resolved, or the disruption becomes the new normal that Iran’s leadership is prepared to weaponize indefinitely.
