Welcome to Episode 10 of No Wall They Can Build, the Ex-Worker Podcast’s serialized audiobook exploring borders and migration across North America. Over the past two months, we’ve explored the ins and outs of irregular migration across the US/Mexico border. Where does it leave us? As the crises produced by climate change and economic exploitations intensify across the world, revolutions turn in to wars, which beget tyranny, which in turn provoke revolutions. In this climate of escalating chaos, what can we do? This episode explores the meaning of revolution in the twenty-first century, looking at the forms it has taken and assessing what it would take to defend it today. The Zapatista struggle offers one of the most durable and promising models of autonomy we’ve seen in recent decades—yet the limits it has encountered point towards unavoidable contradictions facing those who wish to avoid warfare and bloodshed but also cannot defend their achievements against remorseless foes without the force of arms. A harrowing story about the siege of San Juan Copala, an indigenous community whose effort to secure autonomy from the Mexican state was brutally crushed, illustrates the agonizing dilemma that faces would-be revolutionaries today. This episode offers an unflinching look at the perils confronting those who would defy these global systems driving displacement and death, setting the stage for our final installment next week on solidarity and coming home.
