Thousands of people around the world are maimed and killed by landmines and unexploded ammunition every year. International law classifies landmines as 'evil in themselves', but minefields are expressions of 'political minefields' that create them and allow them to persist. In this travelogue through Iraq, Laos, Cambodia, Bosnia, Afghanistan, Sudan, South Sudan and New York City, we follow Matthew Bolton's quest for solutions to the landmine crisis and emerging autonomous weapons. Throughout his journey we meet deminers, paramilitaries, journalists, mercenaries, diplomats, aid workers, and campaigners working in and around the minefields. It is a must-read for those working to alleviate the devastation of war.
