Where do terrorists get the weapons from that they will use against us?
Countries that have tech that can't use it will most likely give it away.
N. Korea is esentially a bankrupt and starving nation and having finished nuclear tech to sell is very lucrative.
We should nip it in the butt. Send the airforce to knock out the plants and all things involved. Say "Hey we warned you" and if they try and come back we send the air force back in to knock out what's left. Ground troops are needed minimally in this kind of war. We don't have to go cave to cave.
