At first, there was the temptation to make jokes about North Korea's bellicose challenges to its neighbors and against the United States. After all, they really couldn't be serious about starting a full fledge war on the Korean Peninsula. The entire North Korean leadership has a 'Dr. Strangelove' feel to them. The entire situation solicits humor and dismissal.
However, the Korean Crisis could lead us to the most serious confrontation since the Cuban Missile Crisis. The United States must start preparing for any eventuality.
To fully understand our current situation, just imagine a 29 year old young man addicted to war video games. He sits all day playing fake war and seeing if he can run up a huge score and become a winner. The person is clearly addicted, delusional and not really operating in the real world of politics. You have just read a description of North Korean leader Kim Jong-un.
Kim Jong-un has no grasp on reality. He process nuclear weapons. At the worse, he can maybe reach remote Alaska with some of them. Most of the near East is in range of his warheads. Certainly he is also capable of smuggling in nuclear devices into the United States. He is a very dangerous man.
Our great hope is that through diplomatic channels that a consensus will be reached with China about North Korea and they will step to the plate to bring him to his senses. If that is not possible, we can only hope that China will be appalled at having someone so unstable at their doorstep that they will intercede and bring stability back to their sphere of influence.
If he suddenly uses nuclear weapons and invades South Korea, remember there are at least 30,000 to 50,000 Americans in South Korea.
What is clear is that the world can't expect a twenty-nine year old delusional leader who has lived in total isolation all his life and is a self-proclaimed deity to make sane and rational decisions. This is a very serious situation.
