Dear abloke,
That was the exact idea in my mind when i posted the info'! If only the Defense labs in USA had such restrictions, China would not have developed such hi-tech nuclear missiles, thanks to the data theft and transfer to China! North Korea which gets it's technology from China, would have been like a subdued cat rather than a growling tiger, ready to pounce on anyone, anytime! You really don't know the fear factor N.Korea is in Japan, South Korea and USA!
