I hate to tell you this but bombing the launch sites is asinine and something only a Clintonoid would recommend. You bomb them before they get nukes not afterwords. Go back to DU.
Firstly, I am not a member at DU, I am a former member of the USAF and I served in Korea.
NK is a very small place, a very poor place and their total assets are slim. What they do have is a bunch of troops, infantry and a few launce sites and hardened storage facilities.
If you use air assets to take out the launch facilities, they chances of them rebuilding are very slim.
Perhaps you might want to read a profile before you shoot your big, fat mouth off.
