Weapons of Mass Destruction (WMD) also known as “unconventional weapons” possess the capacity to inflict death on a massive scale. First and foremost, nuclear weapons are the most destructive of all because they are explosive devices that release huge amounts of energy and lethal radiation as a result of a self-sustained chain reaction achieved by splitting atoms of fissile material, either Highly Enriched Uranium (HEU) or Plutonium. Second, chemical weapons and toxic chemical agents in liquid or gas forms can cause incapacitation, injury or even death in the targeted population. Third, biological weapons are infectious diseases that cause incapacitation or death in the target population by causing serious illnesses. Although a worldwide norm has been established which prohibits use and even possession of nuclear weapons, for biological weapons and chemical weapons the full implementation still has not been achieved. Today, a world with WMDs is more dangerous since as countries proliferate further, then the possibility of non-state actors' acquisition of WMD capabilities increases parallel to it.
