>>I think they have a nuke or two.

I don’t think they do. They blew up 3 very light explosions over the last decade, which would require actually higher tech. than normal. I think they just put a few hundred tons of leftover fertilizer that they got from South Korea a decade ago and blew it up.

You are 100% correct. The propaganda coming from our cult media and theirs
when they supposedly popped the bomb supports the assumption that
they have nothing but radioactive dirt. If it were true they lit up a nuke
more analysis would've been made, and being made even to this day.

TnT could've made that blast inside the hill, in a cave.

I think they just put a few hundred tons of leftover fertilizer that they got from South Korea a decade ago and blew it up.

Here is an article discussing radionuclide evidence that has been collected at locations in South Korea, Okinawa, and Russia.

I will attempt to summarize it as follows: there is some convincing evidence that NK did succeed in detonating a very small nuclear device in the spring of 2010, as they announced.

The phrase "detonating a nuclear device" does not mean that they have a nuclear bomb. It means that they (probably) induced an explosive nuclear chain reaction to take place in an underground cavity.

The article is interesting, anyway.
