Iran – Israel, USA, Gulf conflict
- UKMTO reported a commercial vessel was struck by an unknown projectile in the Strait of Hormuz on August 18, causing crew fatalities.
- U.S. President Trump announced that Washington is not seeking to extend the expired interim deal with Iran.
- Iranian officials threatened military action to break the U.S. naval blockade and warned shipping firms against backing American operations.
- Strait of Hormuz commercial ship traffic remained in single digits per day amid ongoing U.S. blockade enforcement.
- Saudi Aramco offered crude oil delivery off Fujairah as an alternative route to bypass the Strait of Hormuz.
The expiration of the U.S.-Iran diplomatic deadline on August 17 without an agreement coincided with a lethal attack on a commercial vessel in the Strait of Hormuz on August 18. United States forces maintain a naval blockade against Iranian shipping while Tehran threatens military strikes to break the blockade.
The United Kingdom Maritime Trade Operations reported that an unknown projectile struck a commercial ship in the Strait of Hormuz on August 18, killing crew members. Daily ship transits through the strait remained in single digits, though marginally higher than weekend numbers. In response to Hormuz disruptions, Saudi Aramco offered crude deliveries off Fujairah to bypass the waterway. Iranian military officials issued warnings to commercial shipping operators collaborating with U.S. naval forces.
U.S. President Trump announced that Washington will not extend the interim cessation framework with Iran following the expiration of the diplomatic deadline. Iranian negotiators rejected American control claims over the Strait of Hormuz and reported no progress toward a final agreement. Turkey offered mediation support to revive talks between Washington and Tehran, but no formal negotiations resumed.
Regional energy markets reacted to the diplomatic breakdown with rising oil prices as supply risks along Gulf shipping routes increased. The United States redeployed military resources from East Asia to support Middle Eastern operations, reducing joint drills with South Korea. Iran maintained its posture against U.S. naval forces in the Gulf of Oman and Strait of Hormuz, while Gulf Cooperation Council states braced for renewed commercial traffic disruptions.
The failure to extend diplomatic arrangements combined with fatal maritime strikes increases the probability of direct U.S.-Iran naval combat in the Gulf. U.S. naval enforcement and Iranian counter-threats near Hormuz leave commercial maritime traffic exposed to immediate armed attack. Assessment: The theater risks rapid escalation into open naval engagement following the collapse of the interim ceasefire framework.

COMMON QUESTIONS
Is Iran at war with Israel and the United States?
There is no declared war. Iran and Israel have exchanged direct military strikes, United States forces are engaged in the region, and the pressure extends to sanctions and to shipping through the Gulf. The index sits high because that fighting is real, not because war has been declared. Iran, Israel and the United States all appear as conflict parties in Geneva Academy's worldwide classification — the strikes register as interstate hostilities even without a declared war. The index reads 53/100 as of 1 January 1970 (limited armed conflict); above 50 it grades the fighting itself rather than the risk of it.
How dangerous is the Iran and Israel, USA, Gulf situation right now?
The index reads 53/100 — limited armed conflict. The scale is anchored on 22 historical episodes from 1914 to 2005, so the number means the same thing from one theater to the next. It is a measurement of what is reported, not a forecast.
How is the Iran and Israel, USA, Gulf risk index calculated?
By fixed formula from open-source reporting: events are extracted and graded by how well evidenced they are, scored across weighted factors, and the model never picks the number. How the index works, and what it does not measure, is explained at wwiii.report/methodology.
How often is this updated?
Every day. The report is rebuilt from that day's reporting and the index re-judged from it, and a fall is published only once the evidence confirms it.

One 0–100 scale for the whole conflict. 0–49 is escalation before war; 50–100 is active war and how far it has gone.
50 is not a threshold the number can cross on its own. Which side a theater sits on is decided by whether verified belligerents are fighting there, so war onset always moves the score up across 50 — the number never declares a war by climbing.
It is a stage, not a probability: 42 is not a 42% chance of war. Below 50 it grades movement toward war, above 50 the war itself.
Why it moved, under the chart, names what changed in the latest move: the day’s readings — strikes, casualties, talks — and, when the conflict’s stage was re-judged, what was graded differently and the events behind it. Open it for the detail.
Re-judged from open reporting by fixed formula — the model never picks a number — and a fall publishes only once the evidence confirms it. A dot on the line is a day the stage itself moved. How it is made →
Direction — which way the week pushed. Severity — where the index sits. Connections — how much of the rest a shock here reaches. Cascade — that reach combined with how ready this theater is to go off.
The index reads the state of the conflict, not the volume of news. Each run grades the factors listed below against fixed rubrics, and the score follows by formula.
So a dramatic headline moves nothing unless it changes a grade. A theater already graded for recurring incursions absorbs one more without moving — it is priced in.
Open How this was measured for every grade, its movement since the last run, and the events behind it. Full construction →
A different measurement from the score above, from a different source. This line counts how much of the world's news reports conflict between these two states, against their own long-run normal: 100 is normal, 200 is twice the usual level.
It is computed mechanically from the GDELT Project's open event stream every 15 minutes and never touches the assessed index above — when both move together, that agreement is the signal. A day with too few events shows no reading rather than a guess. Click the chart for the full history.
