A few hours ago the American style campaigner, Defense Minister Tomomi Inada resigned from her position.
The impending crisis of North Korean Nukes and ICBM's looms over Japan. Despite new North Korea sanctions from USA & Japan the use of North Korean underground nukes may be ongoing. There is concern that North Korea is hypothetically approaching Hiroshima 15 kiloton size in nuclear weapons designed yield. If the yield estimates are actual and in possession by North Korea they are 1/3 of the way to a Hiroshima size warhead.
And, on the off chance North Korea is superior with nuclear missile rocket telemetry in conjunction with a magnified solar climate, the design yield of those smaller nukes may be magnified. That means a nuclear warhead of only 7.5kiloton design yield would be needed to create a 21st century Hiroshima sized catastrophe, that killed over 180,000 Japanese civilians.
However, beyond scalar weaponry:- it seems to be a scientist's fantasy that North Korea may be capable of using Nuclear weapons & sun, bomb, earth dynamic telemetry to embattle USA's secretive tectonic weaponry.
This writer proposes that some EMP capable ally disable North Korean nuclear progress if there is a way to spare Japan another nuclear winter.
