So you base the assumption that North Korea has no nuclear weapons on the fact they tested a nuclear device and said it was "10km underground" and don't have the ability to dig 10km down?
How about if i tell you the Punggye-ri Nuclear Test site in North Korea is just digging into the side of the mountains? and they don't need to dig a 10km borehole, and North Korea just lies about it being 10km underground so it's people are not worried about fallout.
And how pray tell do you cause a 6kt explosion? I suppose you could do it with 6000 tons of ANFO. More then likely it was a nuke.
I don't see anyone denying that the latest test was not a nuclear device. Russia, China, the US, North and south korea all said it was a nuclear device.
