And who all knows what else this crazy man has envisioned to enable him to attack his enemies. North Korea is considered behind in their military preparedness but then when you have the numbers of weapons he has and the close proximity to South Korea and Japan it doesn't take much to cause horrible damage and destruction. Now he has missiles that put the United States and much of the world within his reach his main decisions is about who to attack and when.
The thought is how to stop him, if that is possible, without provoking him to action unannounced. If he has anthrax then you can assume there are plenty of other horrible things he can unleash, including the nuclear weapons, upon whomever he decides to unleash them. The real question is ... is this many really this insane as to actually contempt or try using them? I worry that he is and that time is running out for options that will not include massive loss of life. So easy it would be if Russia or mainly China could take him out and handle it from the inside but doubtful that will happen either. China might concern themselves that if they tried such and failed that he would then turn his insane retribution toward them.
