The temptation in most world capitals will be to denounce North Korea’s Wednesday nuclear test but do little beyond attempting to bribe dictator Kim Jong Un with more cash in return for more disarmament promises. The more realistic view is to see this as another giant step toward a dangerous new era of nuclear proliferation that the world ignores at its peril.
Pyongyang says the explosion, its fourth so far and first since 2013, was a “completely successful” test of a miniaturized hydrogen bomb. That would represent a technological leap, as H-bombs can be thousands of times stronger than the atomic weapons that North Korea tested previously. Pyongyang often lies, and the White House said Wednesday the initial U.S. analysis suggests it wasn’t an H-bomb.
But even an upgraded atomic bomb using boosted fission would give Kim a more powerful weapon than the bombs dropped on Hiroshima and Nagasaki. Kim is estimated to have enough uranium and plutonium production for 50 to 100 bombs by 2020.
