Every so often, in a magazine/weapons storage facility, one needs to check the ordnance or even send back to manufacturer for strip down and rebuild. Nukes are a case in point.
So think of NK as nothing more than a round of ordnance. It is in storage and needs to be reburied from time to time. I mean if the air pirates of banksterdom can drop MOABs from Aleppo to Aden killing unknown and unnumbered civilians then why has NK not been cluster bombed with McPukes and Subway subnutritions these past decades?
Because the hand grenade that is NK will have its pin pulled at the time required to ignite the whole ammo dump.
BTW have you ever wondered what is so hardened, I mean deep down, and so tough, in Arabia Felix? Who built it? Just to put this one out there as a possible answer. The pouring of massive reinforced structures is a Korean speciality, who built the ports around Arabia starting in the 1950s?, so where does a country with only 2 graduates and a dog stew in 1946 get those skills?
If you are dumb enough to think that the Korean Police action taught them how to build DUMBs then you will believe that the same shooting match also gave Japan its lead in commercial semiconductors and optics because Mr Honda built a put-put and Sony san needed his rice just so!! Japan was Korea and Korea was Japan in 1940.
I love all this satellite imagery that we can never get when the pirates are operating over Syria. Mind you all these HD televisions are all pixellated now when something is there of interest to see. Only fools would watch the shit from the GGT and MnM in HD PixelVisions. Why don’t you just save a stack of cash and get someone to piss in your eyes when you watch the NEWS on an old telly?
Figure 1. Portals at North Korea’s Punggye-ri nuclear test site.
Figure 2. Construction related to a new portal at North Korea’s nuclear test site.
Figure 3. Further evidence of a new portal at North Korea’s nuclear test site.
- The East Portal, the site of North Korea’s first nuclear test in 2006, which does not appear to be maintained.
- The North Portal, used for tests in 2009 and 2013 and previously known as the West Portal, but more properly is described as lying North of the main support area, which continues to show signs of activity.
- The South Portal, which has been under construction since 2009.
- The new West Portal—North Korea’s fourth area at which it can conduct nuclear tests.
If this is the case, Pyongyang would be able to conduct additional tests in the future. One limiting factor is the physical size of the mountain—how many branches can be constructed with sufficient overburden to contain nuclear explosions conducted within. A second challenge is so-called tired mountain syndrome—the hypothesis that repeated nuclear explosive tests will weaken the rock in the mountain, leaving it unable to contain nuclear explosions. US nuclear weapons designers debated whether cracks observed at Rainier Mesa at the Nevada Test Site indicated “tired mountain syndrome.” The North Koreans may have similar concerns or uncertainties.
 On October 30, Yonhap reported that North Korea was constructing a new tunnel for nuclear testing at the Punggye-ri nuclear test site. “North Korea appears to be in the process of digging another tunnel,” an anonymous official said citing the “movement of people and cars at the nuclear test site.” See, “N. Korea digging new tunnel at its nuke test site: official,” Yonhap News, October 30, 2015, http://english.yonhapnews.co.kr/northkorea/2015/10/30/64/0401000000AEN20151030002800315F.html.”
