Darren is back at the mic after a month away and, again, back on the Iran/Hormuz story. The deal he spent an hour analysing in June is dead inside three weeks, the two sides are fighting again, American soldiers are dying, important infrastructure has been destroyed across the region, and a fresh ceasefire proposal is circulating even as Washington weighs a much larger campaign alongside Israel.

This episode is his effort to describe the machinery that keeps generating these crises, with his analysis intended to hold up whether there's a ceasefire or a major escalation by the time you listen. Darren starts with the collapse of the June memorandum and why the agreement that used the word "permanent" turned out to be the shortest-lived of the lot. He then works through what Tehran believes it saw in the three weeks after signing, a short theory of how wars stay limited and how those limits break, and the idea that sits at the centre of the episode: that this is no longer a war about what the two sides don't know, but about their inability to make any promise the other has reason to believe.

From there it's the oil clock — how close the market is running to empty, and why the cushions that saved us the first time may not be there again. Then he moves to the the risk that Iran's apparent victory is quietly turning into a trap, what a durable settlement over the Strait of Hormuz might actually look like, and why none of it touches the nuclear question that started the war. The episode closes well beyond Iran, with a more general thought about a world economy that has become cheap to disrupt, slow to reassure, and which no government can any longer credibly promise not to weaponise.

Australia in the World is written, hosted, and produced by Darren Lim, with research and editing by Hannah Nelson and theme music composed by Rory Stenning.
