Nah, they might find pieces of our cruise missile. Not that they could do anything about it. But I'd rather they didn't know they were hit. I think it would set them back further - trying to find out what went wrong on the pad.
I'm thinking stealthy Global Hawk with the smallest ASM we have. Chances of finding and identifying pieces of a small unguided missile after a TD-2 goes up on the pad are just about nil...
Maybe we could do only one better...
Test fire those experimental airborne laser systems....
NO DEBRIS -- except their own junk...
