No rose colored glasses, here, but it’s true that 10 years ago they tried to fake us out by blowing up an other-worldly amount of conventional explosions in order to try to fake it.
My gut instinct this time, however, is that it’s real....
The 2006 test, while low magnitude, was a legitimate test; fission products were detected.
The larger 2009 test was well sealed, but at 2-6 kilotons it would be a truly enormous amount of conventional explosives; there’s no evidence it wasn’t a real test.
My gut says it’s another fake, with lots of H.E.
This is only a tad stronger than 2009. Does South Korea and Japan provide North Korea with nitrate fertilizer? You think maybe they’re taking this free fertilizer, stuffing it in a deep tunnel and lighting it up?
There never is any radionuclides released until way after the fact...as if someone forgot to let them go.
