I like the Rods From the Gods satellite. Its a great idea that never really championed.
The tech is 1950s to make it reality. Modern comps could target it to insane precision. The only ‘cost’ is the payload getting a few dozen Tungsten phone poles into orbit.
Must be no profit in it for Defense Contractors.
But it sure would solve the Iran problem in 10 seconds with no fallout.
Sounds like something from a Dale Brown novel.
