• Australia's 'barking mad' bet on nuclear submarinesThe multi-billion dollar AUKUS defence deal between the US, UK and Australia is one of the most significant in our modern history. The three countries wanted to curb China’s growing military presence in the Indo-Pacific. To do it, Australia was going to get new nuclear-powered submarines. But in the five years since the agreement was first announced, it’s been anything but smooth sailing. In this week's episode of The Conversation Weekly, we speak with Hugh White, a security and defence analyst at the Australian National University, to explore how the secretive deal was struck and why it's proving so controversial.

• Ratko Mladić: the war criminal who became a martyr for Bosnian SerbsTo most of the world, former Bosnian Serb military general Ratko Mladić was a brutal war criminal whose actions during the Bosnian War killed thousands. For others, he was a martyr who defended the Serbian people. In late August, the 84-year-old died while serving a life sentence in The Hague for war crimes and crimes against humanity. He was laid to rest in Belgrade earlier this week with full military honours - a move which angered the families of the victims of his crimes. On this week's episode of The Conversation Weekly, why a war criminal being celebrated by some as a hero and how this is reopening old wounds in one of Europe’s most divided regions.

• How Ukraine is bringing the war home to RussiaIn recent weeks, Ukrainian drones have targeted large warehouses across Russia, destroying millions of dollars of merchandise stored inside them. These warehouses and logistics hubs belong to Wildberries, the Russian equivalent to Amazon. They're also taking aim at Ozon, Russia's second largest online retailer too. Ukraine says it’s targeting these companies because they’ve been providing supplies to soldiers on the front line. But as the war drags on well into its fourth year, is there anything that could put pressure on Putin to withdraw troops from Ukraine? Read more from Matthew Sussex here.

• How Timor-Leste is fighting back against Asia’s scamming gangs🔁 Rerun: originally published 12/12/25. We're revisiting this episode as we take a quick break but we'll be back next week with a new instalment of The Conversation Weekly. Oecusse, a rugged, remote district of Timor-Leste in south-east Asia, is usually a pretty sleepy place. But in August, Oecusse was rocked by a large police raid on a suspected scam centre, later linked by a UN report to organised crime networks running scamming operations across south-east Asia. And then in early September, a Facebook post by one of Timor-Leste’s highest political officials made some explosive allegations about a murky criminal underworld trying to get a foothold in the country. In this episode, we speak to Michael Rose, an anthropologist and adjunct lecturer at the University of Adelaide who has lived and worked in Timor-Leste, about how Asia’s scamming gangs set their sights on Timor-Leste as their next frontier – and the movement to keep them out. This episode was written and produced by Katie Flood and Gemma Ware with assistance from Mend Mariwany. Mixing by Michelle Macklem and theme music by Neeta Sarl. Gemma Ware is the executive producer.

• Loonies and bins: Britain's long love affair with novelty politicsIt's pretty grim when your main political opponent is a man with a bin for a head. That's the situation that's faced Nigel Farage in the Clacton byelection in the UK. Count Binface has pledged to nationalise the singer Adele, cap the price of ice creams and build at least one affordable house. It might sound surreal, but the count isn’t the first satirical candidate in election history. Historian Richard Toye argues we should take them seriously. You can read his analysis on our website. This episode was written and produced by Isabella Podwinski, Justin Bergman and Ashlynne McGhee. Sound mixing is by Michelle Macklem and our theme music is by Neeta Sarl.
