When the Outer Space Treaty was ratified in 1967 by the USA and USSR it was believed that, for the foreseeable future, outer space would be a 'zone of peace'. However, despite the ratification of the Treaty by a further 72 nations by the end of 1976, this illusion has been shattered during the last 10 years. Indeed, in recent years more than 60% of both US and Soviet satellites launched have been military satellites.
