no i'm genuinely convinced people are stupid enough to think the diamonds could be used to make things other than drillbits and other precision points
chip the diamond
Like I said, we have very good missile defense system that will probably spot, intercept, and destroy/disable/prematurely detonate an incoming nuke before all of DC looks like fallout three.
Rock couldn't chip a diamond unless it collided with said diamond at a really high speed.
And even the best missile interceptors aren't foolproof. These things can't be expected to stop every nuke fired, especially if you unload them in the hundreds or thousands.
