I dunno. 4+ years ago, they successfully set off a nuclear weapon.
I'm guessing at the very least, they have the ability to do that again.
To me, that's not acceptable. however, some appeasers think bribing them to not nuke us is the way to go. I am of the ilk that you can't negotiate with terrorists.
(Remember....they can't even guarantee a successful launch of their long range missiles...which can't reach any major US cities anyway...)
The "nuclear" bomb in 2006 was a pipsqueak fission reaction that was less than a kiloton in yield. The estimates on its yield go as low as 550 tons...
Disregarding the difficulties in enriching Uranium, and the fact that even the NEWLY released information on North Korea's enrichment program indicates that they have a MAXIMUM capability of producing about ONE minimal payload worth of weapons grade U235 a year, the "bomb" in 2006 was a couple of Kilotons at BEST...which would have to be loaded onto missiles with high failure rates at launch and without the capabilities of ever even making it to major American cities if used to attack us....
The bombs we dropped in 1945 had explosive yields of 12,500 and 22,000 tons.
Tsar Bomb tested by Russia was half of what was originally a 100,000,000 Ton yield.
See the difference? 550 vs. 100,000,000?
So you don't have to go search for a calculator, that means
it would take close to 200,000 North Korean "bombs" to equal ONE SINGLE full-strength Tsar bomb. At an enrichment rate of 1 bomb per year with the new findings, that means that they'll have a stockpile
equal to that SINGLE bomb in the year 202010....The fucking 2006 "bomb" explosion wasn't a "chest thumping" by North Korea. It was a RELIEF to Nuclear Engineers and Physicists who weren't sure of their capabilities.
You don't "test" a bomb with 1 kiloton of yield. If you can only produce 1k of fissionable Uranium for testing purposes, then you don't have megatons sitting back at home.
Considering the yield-to-weight ratio they probably got out of the thing, they took every drop of U235 they had and crossed their fingers for a chain reaction.
(For reference, the Trinity "test" was over 20,000 tons in yield....65 years ago)
The US has 15 or so GBU-43/B's at 165 tons of guaranteed to launch successfully and reach their target yield that would clear out every major North Korean military base
WITHOUT USING NUCLEAR TECHNOLOGY before Kim Jong Fever's "Tinkering Tom" crashes into the ocean somewhere.
Unless Russia wants to see MAD play out, they could send out 11 or so FOABs at 44 tons a piece (NON-NUCLEAR) to hit any other selected targets they'd like before the North Korean commanding officers get the news that their "bomb's" only fatality was a beluga whale somewhere in the Pacific.
*In case you didn't catch it....the yield of 11 FOABS is ~575 tons...MORE than the North Korean "nuclear" bomb....and decidedly non-nuclear in payload.
