We are seeing injustices caused by war and occupation unfold in real-time via social media, and we are speaking out in our millions against these horrors. Yet, from Gaza to Ukraine, the bombs continue to fall. We must understand why this is happening if we are to end it. ‘Monstrous Anger of the Guns’ lays bare the dark and deceitful world of the global arms trade, which, often funded in our name, is a business that counts its profits in trillions and its losses in human lives. Leading activists and campaigners connect the dots, showing how notions of citizenship, democracy and trust in governments are misguided, and how we can fight back by building mass movements, using direct action and legal justice to end the flow of weapons and the environmental and human devastation they bring.
