Book excerpt: Nuclear, biological and chemical weapons are designed to cause destruction on a vastly greater scale than any conventional weapons, with the potential to kill thousands in a single attack and with effects that may persist in the environment and in our bodies indefinitely. This report by the independent Weapons of Mass Destruction Commission, chaired by Dr Hans Blix, sets out 60 recommendations on how the world community, national governments and civil society should address this global challenge under the following headings: preventing the proliferation of nuclear weapons; preventing nuclear terrorism; reducing the threat and numbers of existing nuclear weapons; moving from regulating nuclear weapons to outlawing them; biological and toxin weapons; chemical weapons; weapons of mass destruction (WMD) delivery means, missile defences and weapons in space; export controls, international assistance and non-governmental actors; compliance, verification, enforcement and the role of the United Nations.
