Space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of preeminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theatre of war.
President John F. Kennedy, Address to Rice University, September 12, 1962
Nuclear, chemical and biological weapons, collectively known as Weapons of Mass Destruction (WMD), present a serious danger to humanity. These weapons, once recognised as tools of deterrence available to State actors, are now even feared as the weapons of choice for non-State actors. During the last few decades, the perceived threats from WMDs has become a significant issue in the foreign policy and national security agendas for many nation-States.
