Battle Lines

North Korea’s dynasty dictatorship has taken on a new leather clad, second-in-command. Reports from South Korea have suggested that Kim Jong Un’s daughter Kim Ju-ae is now the heir apparent in the totalitarian state. Could she one day be the youngest person to command a nuclear arsenal? Roland chats to The Telegraph’s Lily Shanagher and from the University of Oxford, North Korea watcher, Dr Edward Howell, to unpack what we know from the shadows.Plus, after the Munich Security Conference at the weekend, Europe is facing a new future without Washington’s steadying hand and will have to be less reliant on the Stars and Stripes. But is European defence manufacturing scaling up in line with these new demands? Roland speaks to Philip Lockwood from defence startup Stark to find out just how quickly the ambitions are being realised. Read Lily's article on Kim Ju-ae: https://www.telegraph.co.uk/world-news/2026/02/16/kim-opens-neighbourhood-families-soldiers-killed-ukraine/Pic credit: KCNA via ReutersProducer: Peter ShevlinExecutive Producer: Louisa Wells► Sign up to our most popular newsletter, From the Editor.

Donald Trump has moved the war for critical minerals from the margins of policy to the heart of great power rivalry. In this episode of Battle Lines, we look at Project Vault, America's bid to take back control of the critical minerals and rare earths supply chain from China. This bid to build a vast new stockpile and industrial strategy was unveiled at the inaugural US Critical Minerals Ministerial Summit last week. Supporters see it as a necessary first step to protect American industry and national security. Critics warn that for middle countries, it may simply shift dependencies rather than break them.Venetia talks to Sibylline Chief Analyst Sam Olsen to unpack what Project Vault really means, why processing matters more than mining, and how China has weaponised its dominance in ways OPEC never could. Plus, a deep dive on how Greenland fits into the West's rare earths strategy. Greenland Energy, Business and Mineral Resources Minister Naaja Nathanielsen on that Trump deal, Chinese influence and the challenges of mining on the island. Producer: Peter ShevlinExecutive Producer: Louisa Wells► Sign up to our most popular newsletter, From the Editor.

The United States appeared poised for a major military confrontation with Iran after Donald Trump ordered a powerful naval force into the region in response to the killing of thousands of Iranian protesters. The expected strikes never came. Instead, Washington has shifted towards using military pressure as leverage for a renewed nuclear deal.Does this mark a genuine de-escalation? Or is it merely a pause before conflict? As diplomacy falters, tensions remain high and, inside Iran, the regime faces deepening political fractures as internet blackouts lift and grim details of last month’s massacres begin to emerge.Roland is joined by The Telegraph’s Akhtar Makoii and Sascha Bruchmann from the International Institute For Strategic Studies.Producer: Peter ShevlinExecutive Producer: Louisa Wells► Sign up to our most popular newsletter, From the Editor.

Xi Jinping is purging again. Generals once seen as untouchable are gone, rivals erased, loyalty enforced through fear. Is this the move of a leader under real threat or the paranoia of a man who has ruled too long and trusts no one? To find out more, Venetia talks to Oriana Skylar Mastro, director of the Indo-Pacific Policy Lab at Stanford University’s Freeman Spogli Institute for International Studies.UK Prime Minister Keir Starmer has been to Beijing, the first British leader to do so in eight years, talking trade, visas and whisky tariffs while security concerns barely made the script. We hear from The Telegraph’s Ben Riley-Smith, behind the smiles come burner phones, burner laptops, fears of honey traps and even planes being bugged. Economic opportunity versus national security. Values versus power. Meanwhile Britain faces its own reckoning. Spies in Parliament. Phones hacked inside Downing Street. A vast Chinese mega embassy rising in central London amid warnings from MI5. Venetia is joined in the studio by The Telegraph’s Gareth Corfield and Rozina Sabur to discuss the extent of the national security threat posed by China.Read Rozina Sabur's hacking scoop: https://www.telegraph.co.uk/news/2026/01/26/china-hacked-downing-street-phones-for-years/Read Gareth Corfield's embassy scoop: https://www.telegraph.co.uk/news/2026/01/12/revealed-china-embassy-secret-plans-spy-basement/Read Colin Freeman's analysis: https://www.telegraph.co.uk/news/2026/01/27/general-zhang-youxia-chinas-nuclear-secrets/Producer: Peter ShevlinExecutive Producer: Louisa Wells► Sign up to our most popular newsletter, From the Editor.

Gaza has entered the next phase of the peace process but is the ceasefire actually bringing peace?This week, Venetia Rainey and Arthur Scott-Geddes speak to Tess Ingram, UNICEF spokesperson who has just returned from four months on the ground. She outlines the humanitarian situation following the ceasefire, from winter shelters and malnutrition to unexploded ordnance, orphaned children, and the daily challenges facing civilians.Plus, The Telegraph’s Global Health Security Editor Paul Nuki examines Donald Trump’s controversial Board of Peace: how it works, why it has divided international allies, and what it could mean for disarming Hamas and the future of the conflict.Read Paul's article on how Northern Ireland can provide a roadmap for Gaza: https://www.telegraph.co.uk/world-news/2026/01/23/how-northern-irelands-peace-can-provide-a-roadmap-for-gaza/Producer: Sophie O'SullivanExecutive Producer: Louisa WellsStudio Operator: Meghan Searle► Sign up to our most popular newsletter, From the Editor.
