This was the concept of the mx missile program (peacekeeper icbm) - the shell game concept was to have miles and miles of tracks with multiple launch sites, and to consistently move live and dummy missiles between them - that way there was a large number of potential targets and uncertainty as to which targets contained live missiles - I think the Chinese are now building a similar concept to this in the Gobi desert (if memory serves).
