"You don't control the skies if you aren't there."
.....and you don't control the ground if you aren't in it. That's why, taking your lead, I am now worried about the North Koreans and Chinese developing fighters that fly through the earths crust. Swarms of Crust-Fighters, launched in overlapping waves would overwhelm us, leading to certain defeat.

245 - "Swarms of Crust-Fighters"
Wow - you are right. Now, we have the technology to defeat these earth crust fighters, just dig a big hole, under our country, then these fighters would have nothing to dig through.
Technologically possible - we can dig this big hole. Yes, it's the only sensible thing to do.
