At the turn of the century, the movement against capitalist globalization exploded onto the world stage with mass mobilizations in Quebec City, Washington, Genoa, and other cities. Anarchists faced off against heads of state, captains of industry, and riot police by the thousands. While the authorities sought to bend all living things to the profit imperative, anarchists set out to demonstrate a way of fighting that could open the road to a future beyond capitalism. The twenty-first century was up for grabs. And every time, Tomas Rothaus was there, fighting on the front line. In Another War Is Possible, we follow Tomas from his days as a young militant to his tenure editing the publication Barricada. In vivid prose, he recounts the lessons he learned from veterans of the Spanish CNT - his first experience trading blows with police in the streets of Paris - his adventures slipping across borders to participate in epoch-making riots. With Tomas, we breathe tear gas, we tear down fences, we tour the squats and battlefields of three continents. Along the way, Tomas shows that the tragedies of the twenty-first century were not inevitable - that another war was possible. His testimony is proof that another world remains possible today.
