The Fourcast

Donald Trump's Iran strategy is unravelling. Days after declaring a ceasefire, the agreement appears to have collapsed. Trump has scrapped plans for a 20% toll on ships using the Strait of Hormuz in favour of major Gulf investment deals, while warning that even tougher military action could still be to come.
So why did the ceasefire fail? Has Iran emerged politically stronger despite months of conflict? And is the Strait of Hormuz still Tehran's most powerful bargaining chip, or is it becoming a liability?
On this episode of Trumpworld, Anushka Asthana is joined by Nate Swanson from the Atlantic Council and British-Iranian author Sanam Naraghi-Anderlini to examine what's really driving the conflict, whether diplomacy is finished, and what Donald Trump's next move could be.

President Donald Trump has U-turned on his threat to charge cargo ships transiting the Strait of Hormuz as much as 20% - but the US and Iran have continued trading strikes as Trump has told the US Congress that war has resumed. 

So, can the US gain the upper hand? Will more US bombs and bullets really help? And has this whole episode proven that the memorandum of understanding, which was meant to end the conflict, was destined to fail.

In this episode of The Fourcast Indicators, presenter Krishnan Guru-Murthy and Defence and Intelligence Analyst, Mark Urban are joined by former US Navy Rear Admiral Mark Montgomery, who is now a senior fellow at The Foundation for Defence of Democracies.

Britain is getting hotter. But is the country ready?
After another record-breaking heatwave, experts estimate that thousands of excess deaths may already have been linked to the extreme temperatures. From overheating homes and buckling railways to schools, hospitals and reservoirs struggling to cope, questions are growing over whether Britain's infrastructure was ever designed for the climate it's now facing.
On this episode of The Fourcast, Krishnan Guru-Murthy asks why the UK remains so unprepared for extreme heat, what climate adaptation should actually look like, and whether the debate around Net Zero has become more political than practical.
He's joined by Professor Rebecca Willis from the University of Manchester, environmental lawyer and Uplift Executive Director Tessa Khan, and architect Smith Mordak to discuss how Britain can prepare for a warmer future and whether the country is running out of time.

Christopher Nolan’s newest blockbuster film The Odyssey, with a star-studded line up including Matt Damon, Robert Pattinson, Zendaya, Anne Hathaway and Tom Holland, hits the cinemas next week, and it’s already causing a stir. 
But what is the film really about? 
On this episode of the Fourcast, Krishnan Guru-Murthy sat down with Christopher Nolan and Tom Holland and explored the themes of revenge, the hero’s journey, homecoming, and asked how the Greek concept of Zeus’s law could be linked to the debate around immigration today. 
Later Krishnan spoke to classicist Edith Hall to delve deeper into the epic tale.

Donald Trump says the ceasefire is over. After fresh US strikes on Iran and retaliatory attacks on American military bases in the Gulf, hopes that the conflict was winding down have been thrown into doubt. 
Trump has declared he no longer wants to negotiate with Tehran, raising fears that the Middle East could be entering a dangerous new phase.
So what do these latest attacks tell us? Is diplomacy finished? Could Israel escalate its military campaign? And what does renewed instability mean for shipping through the Strait of Hormuz and the wider global economy?
On this episode of the Fourcast Indicators Krishnan Guru-Murthy is joined by defence and intelligence analyst Mark Urban and also speaks to Hossein Kanani Moghaddam, founder of the Green Party of Iran and a former senior IRGC commander, to discuss Iran's response, the future of the regime, and whether there is any route back to diplomacy.
