    The Invasion - Part Two: A Vietnamese War In Cambodia

    Why did Nixon invade Cambodia in May 1970? What impact did the 'Cambodian Incursion' have on the war in Vietnam? How did this effect Cambodia? Time Period Covered: May - June 1970 In part two of our discussion about the situation in Cambodia after the coup which pushed Sihanouk from power, we see how the Nixon Whitehouse responded to the crisis facing Cambodia. Lachlan asks whether the decision that Nixon and Kissinger made was the right one, or whether there was a correct answer. We look at the circumstances which brought about the decision, what options were on the table, and the impact that Nixon's speech which announced the 'incursion' had. Then we look at the 'Cambodia Campaign' itself, discussing the fighting which overtakes much of the country, and the outcomes this had in the short, and long term.

    Pol Pot Rises

    Why was Duch released from prison on April 3rd, 1970? How did Pol Pot and the Khmer Rouge transition from small guerrilla enclaves to administering huge areas of Cambodia? What exactly was “Independence Mastery,” and why was it so central to the Khmer Rouge mindset?  Time Period Covered: April 1970 – July 1971  In this episode, we pivot from Lon Nol’s takeover to the Cambodian communist perspective, exploring how Pol Pot and the Khmer Rouge navigated the chaotic months following the coup. We follow Duch’s unexpected release from prison, track Pol Pot’s return journey from Beijing and Hanoi, and see how the Khmer Rouge began absorbing millions of Cambodians into so-called “liberated zones.” Along the way, we delve into the principle of Independence Mastery, the uneasy alliance with the Vietnamese, and the early precursor to S-21 known as M-13. We also uncover the paranoid mindset driving the Khmer Rouge’s suspicion of outside influence, including alleged assassination plots and forced confessions, shadows of the horror to come.  Remember, if you can, to please support the show at www.shadowsofutopia.com/support.  Sources: Chandler - Tragedy of Cambodian History and Voices From S21 Short - Pol Pot Kiernan - How Pol Pot Came To Power ECCC Archives - Duch Trial 2009 Heder - Cambodian Communism and the Vietnamese Model Edwards - Cambodge Harris - Buddhism Under Pol Pot

    The Khmer Republic: The Lon Nol Line and Chenla I

    How did the Khmer Republic try to take back control of Cambodia? Time Period Covered: June 1970 - January 1971 In this episode, we follow the Lon Nol government as it attempts to prove that the Khmer Republic can fight and win.  After the initial chaos of the coup and the brief U.S. incursion, Cambodia’s leaders launch their first large-scale offensive: Operation Chenla I. We look at how the Cambodians, with American and South Vietnamese support, attempt to open Route 6, retake lost territory, and secure the Lon Nol strategy.

    Chenla II: Lon Nol Strikes Out

    What was the political fallout from Lon Nol's Stroke? How did race and religion become such a key theme of his regime? What led to the worst military defeat of the Cambodian Civil War? Time Period Covered: March - December 1971 In this episode, Lon Nol returns to Cambodia after recoving from a mild stroke in Hawaii. While many hoped he might step aside, and that the US might provoke a change in leadership, Lon Nol remained in power. His little brother's influence grew, and his obsession with race and religion became even more pronounced. Amongst the Vietnam War playing out on Cambodian land, the carnage of American bombs became a regular occurrence. Meanwhile, politics in Phnom Penh leaned toward a military dictatorship. By the end of the year, the Khmer Republic had to face its worst military defeat, one that it would not recover from.

    Witness to the end of the Cambodian, and Vietnamese Civil Wars - Jim Laurie

    In this bonus podcast episode, I’ve invited veteran journalist Jim Laurie to reflect on a lifetime spent amid global upheaval. From the Nixon incursion into Cambodia to the oblivious tranquility of Phnom Penh before war erupted—Laurie shares his remarkable memories, including a poignant love story with a local woman, a comparison between the wars in Saigon and Cambodia, and the shock of revisiting Cambodia in 1979 to find destruction everywhere. This episode is enhanced by visuals, including archival footage, that bring his narrative powerfully to life. If you have the opportunity to watch on YouTube, you’ll gain an even richer experience.

    S3: (Bonus) A Brief History of the Thai Cambodian Border Dispute

    Hello everyone, I've put together a quick look at the long history of the Thai Cambodia border dispute to compliment what I'm sure many of you are reading and watching in newspapers and on television. The escalation is far from good, and I hope it simmers down back to - as I'll discuss - a normal state of not-quite-peaceful. I cover the history from 900 CE to 2025, and everything from the 1794 retrocession of Battambang, the Franco-Thai War, Sihanouks ICJ case in 1962, Khmer Rouge border clashes and spies, to the more recent disputes about Preah Vihear. Much of this is based off of a recent bonus episode I made for Patreon, so for those that have listened to that, apologies for some of the overlap. www.shadowsofutopia.com/support

    S3: Interview: Explaining The 2025 Thai Cambodian Border Crisis with Sebastian Strangio

    In this episode, I talk with journalist and author Sebastian Strangio about the border tensions between Cambodia and Thailand that have escalated in July 2025. Sebastian is the Southeast Asia editor at The Diplomat and one of the region’s leading journalists. He’s a former reporter at the Phnom Penh Post, and the author of Hun Sen’s Cambodia (re-released as Cambodia: From Pol Pot to Hun Sen and Beyond) and In the Dragon’s Shadow, a study of China’s growing influence in Southeast Asia.  We start with the political figure who has shaped Cambodia for decades, Hun Sen, and trace how his rise from Khmer Rouge defector to Prime Minister led to the creation of a powerful political dynasty. We then look at the handover of power to his son, Hun Manet, and what that has meant for Cambodian politics in the last two years.  From there, we shift focus to Thailand and explore the structure of Thai politics today. Who holds power? How have coups and party shifts shaped its modern system? And how does that compare to Cambodia’s more centralized model? This helps us understand one of the key triggers of the current crisis: a leaked phone call between Hun Sen and former Thai Prime Minister Paetongtarn Shinawatra.  We then move into the border dispute itself. We look at the long history of territorial claims, colonial-era maps, and temple flashpoints like Preah Vihear and Ta Moan. And we ask how this latest confrontation fits into broader patterns of nationalism, political theatre, and regional rivalry. Finally, we explore what role public opinion and media narratives are playing on both sides of the border.
