RICHARD FALK, DAVID KRIEGER (pictured) and ROBER LANEY – By their purported test of a hydrogen bomb early in 2016, North Korea reminded the world that nuclear dangers are not an abstraction, but a continuing menace that the governments and peoples of the world ignore at their peril. Even if the test were not of a hydrogen bomb but of a smaller atomic weapon, as many experts suggest, we are still reminded that we live in the Nuclear Age, an age in which accident, miscalculation, insanity or intention could lead to devastating nuclear catastrophe.
