Feb. 12, 00:05 a.m. — Our colleagues at CNN provide some background on underground nuclear testing:

Tests are typically conducted in vertical shafts, according to the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty (CTBTO). Holes are cut 1 to 3 meters wide and up to a kilometer deep. The atomic devices are assembled on site and placed in the hole, usually accompanied by lead-protected diagnostic canister that contains sensors to record the explosion. The tunnel is then filled with layers of pea gravel, sand and other materials to prevent radioactive material from being released into the atmosphere.

During a test, the explosion energy is released in less than a millionth of a second, according to CTBTO. The temperature will reach about a million degrees within a few microseconds, and shockwaves from the blast, depending on the size, can be detected by seismographs around the planet.

Congrat Kim Jong Who Cares on your achievement! While your captive population are scrambling for food, the cousins and other relatives of , the country that is really a Democratic Peoples Republic of Korea to your south has become the biggest builder of many complex consumer electronics and cars in the world, with the population living large.

How about if South Korea gets tired of your childish playing with matches and offers every family in a North free of your ridiculousness, a Hyundai, a big screen Samsung TV and a Galaxy S4 phone, and (wait it gets better) a job with a future in factories and engineering firms close to their homes.


The world must not attack North Korea. If they do, they will be giving just reason to the North for their future (re)actions, which will certainly not be welcomed. Deploy the Zionists. The Israeli military will shortly 'dismantle' the danger piece by piece - and get on Iran's nerves at the same time.


Mutual Nuclear Deterrence -MND- is also known as Civil Deterrence, Civilized Deterrence, Civilizing Deterrence.

MND makes both venues unsafe for war.

A few Nukes can deter many nukes.

MND leads to fewer Nukes in the world, voluntary arms reductions, voluntary disarmament, smaller militaries, less war spending..

The right of a Nation State to have defensive deterrent weapons must be recognized, respected, and preserved.

MND is not good for nations, that seek to be the world's dominant military force.

MND is bad for war profiteers.

No nation wants or needs nuclear weapons except to deter belligerent sociopathic governments from attacking.

MND is not MAD

MND is good and the truth.

MAD is bad and a lie.

A few nukes can deter the entire US military.

What Nation dares risk a high speed nuclear weapon coming at one of their cities.

What nation dares cause a nuclear weapon to denote in the biosphere?

A nuclear detonation in the biosphere is an attack on all humanity, all life, and on the human genome..

Any government that does anything to cause a nuclear detonation in the biosphere is an enemy of the biosphere, and an enemy of the human genome.

Mutual Nuclear Deterrence, Civil Deterrence, works and works well.

Civil Deterrence has powerful enemies with ulterior motive$.
