It has widely been acepted that North Korea has possessed one or two nuclear weapons since October 2002. However, this belief seems to be based upon political motives rather than solid scientific evidence.
There are three requirements for a nuclear program which need to be verified before conclusions can be drawn about the existence of nuclear weapons in North Korea:
1. Nuclear materials to produce nuclear weapon
The US suspects that North Korea had already secured enough weapons-grade plutonium to make one or two nuclear weapon before entering the 1994 Agreed Framework. However, North Korea denied this. This fact would be defined when a significant portion of the LWR(Light Water Reactor) project is completed, but before delivery of key nuclear components. Yet it is not clarified.
2. 'Triggering device' to set off nuclear explosion
Let's assume that North Korea might have a triggering device, but it is difficult to say that they successfully developed a triggering decive cabable of detonating nuclear weapons.
First of all, there are great technical difficulties in making a triggering device.
The triggering device is an explosive device designed to compress and bond separated nuclear materials by critical state. It must be precisely designed and made to bond completely spherical shape within one-one millionth of a second. Some scientific experts view the creation of a triggering device in North Korea unlikely and furthermore, the US government has not been able to prove it.
Secondly, some say that North Korea might have smuggled a triggering device, but there is no evidence of this.
In addition, it is worth noting here that the alleged exchange of nuclear technology between North Korea and Pakistan is related to enriched uranium and is not related to the alleged acquisitions of a triggering device.
3. Nuclear Test
Even though they did the test, it is needless to say we can all watch the phenomenon.
And some group stated "North Korea is able to do simulated test if high-leveled computer and technology are supported" but it still not enough to explain because simulated test need actual know-how and they can not afford the computer. as US restricted.
This is the worst-case scenario and just not verified guess. Of course, North Korea has potential capability to develop nuclear weapon by enriched uranium or plutonium through reprocessing spent fuel rods. That is matter of 'future' and subject of 'negotiation' In other words, the key to solve it in a peaceful way up to the US.
