Terry, if you want to invoke scifi space based kinetic energy weapons with precise targeting, try "The Moon is a Harsh Mistress" by Heinlein.
In 1983, Heinlein and I actually came to logger heads, in person, over Gen Graham's abuse of the non-terrestrial materials concepts by O'Neill and Vajk. He had written the foreword to Graham's book "High Frontier" about weaponizing nonterrestrial resources. Graham was a key figure in Reagan's "Star Wars" Strategic Defense Initiative.
