It wasn't even a bit of an h-bomb. Previous tests released the right combination of isotopes to indicate that the devices were plutonium. The very low yields of these tests suggests that the devices are very inefficient, or very small. Perhaps small enough to fit in one of the missile systems they have been testing...
Worrying - and hopefully with China's blessing this lunatic and his dynasty will be put somewhere they will stop causing harm to their own people.

Clock is ticking on North Korean nuclear test forensics

In a news article in Nature yesterday, Declan Butler & Elizabeth Gibney
ask "What kind of bomb did North Korea detonate?"

In order to tell, the hope is that some of the radioactive gasses leaked
from the underground explosion and that prevailing winds will carry them
far enough to be detected for nuclear forensic analysis.

But in order to do so, some of the short-lived isotopes would need to be
measured within the coming days before they decay.

The Preparatory Commission for the Comprehensive
Nuclear-Test-Ban Treaty Organization (CTBTO)
maintain a global network
of radiation monitors.

Last month, satellite imagery had detected that North Korea has been
excavating a new tunnel at the Punggye-ri nuclear test site.

In the Nature news story, James Acton, who studies nuclear policy at
the Carnegie Endowment for International Peace in Washington DC,
also says that the seismic event indicates an explosion in the order of
10 kilotonnes - too small for a H-bomb - but speculates, as I had done
earlier, as to whether it might be a boosted fission device employing small
amounts of deuterium and tritium.

Boosted devices are smaller yet can be just as powerful as fission bombs, making them more suitable for use in missile warheads. The research involved in developing them is also a step along the way to developing thermonuclear weapons.

Without other sources of intelligence, the chances of reliably determining what kind of nuclear weapon North Korea did detonate are low, he thinks.

Richard Stone, in Science, also reports on the test being of low-yield
and speculation of whether it might be a boosted fission device -

North Korea, Pakistan & India and the Comprehensive Nuclear Test Ban Treaty

Backgrounder

The Comprehensive Nuclear Test Ban Treaty was adopted in 1996
and has 183 signatories.

The only three nations that refused to sign are North Korea, Pakistan
and India.

North Korea, Pakistan and India are also the only three countries
who have ignored the test ban.

India and Pakistan carried out two tests each in 1998 and North Korea
has carried out four tests.

India originally obtained the bomb in 1972 under Indira Gandhi.

The plutonium came from a nuclear reactor Canada had donated,
even though Canada had stipulated it only be used for peaceful
purposes.

Pakistan, who had been at war with India, then felt the urgency to build
nuclear weapons to help deter any threat from India.

India and Pakistan have also refused to sign the Nuclear Non-Proliferation
Treaty
.

North Korea then obtained much of its nuclear bomb design know-how
through proliferation from Pakistan.

Despite India refusing to sign the Comprehensive Nuclear Test
Ban Treaty and the Nuclear Non-Proliferation Treaty and despite their
continuing work on Intercontinental Ballistic Missile Systems (ICBM's),
last November Australia agreed to supply India with uranium.

The sleazy government under the Abbott/Turnbull led coalition broke all the rules for the sake of the almighty dollar,
I was surprised that there was not any visible complaint by the US government,or even the United Nations.
The Labor opposition whimpered a very muted reply in parliament,but probably agreed on the quiet.
Cheers

That's what I think too.

Frankly, I am far more concerned with Israel's nuclear program and its (expansionist) territorial and geopolitical ambitions.


...... waiting for the inevitable hasbara - sayanim response/censorship.



google these two words if you are up for a trip down the rabbit hole:

hasbara
sayanim


whilst you are at it, watch this:

you have been 'had' as the saying goes.
