North Korea tested a nuclear device with an underground detonation on February 11, 2013. Along with North Koreas missile program the world moves closer to having a rogue nation with a Intercontinental Ballistic Missile (ICBM).
This is the first test under the leadership of Kim Jong-un.
Why put so much time, effort and money into building a nuclear missile program when people are starving? There have been reports of starvation being so widespread in North Korea that people are resorting to cannibalism.
There are main two reasons for North Korea to develop nuclear weapons – to use the weapons in an act of war, or use the weapons as a bargaining chip.
Nuclear Strike Against the United States
If North Korea were to use nuclear weapons against the United States, it is doubtful the U.S. would respond with its own nuclear attack. Due to the liability and long term sigma, the U.S. would respond with conventional weapons.
China would not tolerate the U.S. nuking North Korea anyway. The nuclear fallout to China poses a great risk. Then there are the North Korean refugees that would flee to China looking for food, medical care and shelter.
