North Korean Wake Up Call; Nuclear Weapons And Their Proliferation Are A Disaster Waiting To Happen

     If there were no nuclear weapons, Trump and North Korean tweets and threats would not matter.  Nuclear weapons holds humanity hostage to the whims of the leaders in possession of these weapons. One small misstep, one deranged leader, can spell disaster.
     The problem with nuclear weapons and their proliferation goes far beyond the personalities of the world leaders presently on stage.
     How did humanity devolve to the point that a growing number of nations hold in their hands weapons that can kill millions or billions and destroy human civilization and most life on earth? How can it  be stopped? What better safeguards can be put in place that will prevent the use of these weapons by less than stable, dangerous leaders?
     If anything good can result from the present crisis, it will be no longer shifting eyes away from nuclear weapons and their proliferation.
