There are compelling reasons to end production and use of the nuclear material. There is enough highly enriched uranium on hand to fuel non-weapon uses of the fissile material for a century. To be sure, when nuclear goes wrong, it really, really goes wrong. There is huge increase in the number of cancer patients along with death rate of cancer patients in the world.
Alarmingly, tensions between the United States and North Korea have again reached crisis proportions. The United States wants North Korea to curtail any further development of its nuclear weapons program, as well as to stop testing its missiles. North Korea evidently seeks to bolster its security by acquiring a sufficiently robust deterrent capability to discourage an attack by the United States. The unpredictable leaders of both countries are pursuing extremely provocative and destabilizing patterns of behavior. Where such dangerous interactions lead no one can now foresee. The risk of this tense situation spiraling out of control should not be minimized.
