Ballistic missile is an object of non-proliferation with nuclear weapon, especially, it can be used as carrier of weapons of mass destruction include nuclear, bio/chemical weapons.

In fact North Korea have threatening ballistic missile program. But it is still early to say that they have ICBM(Intercontinental Ballistic Missile)target to US.

Above all, NK has not covered technical problem completely.

For example, they need three main technology to make perfect ICBM as below.

One is Three-stage rocket and another condition is place warhead in orbit. And finally, reentry from the space to the earth.

Only first technology is done, evidence that Daepodong-1 in August 31, 1998. but it is failed place mini-satellite in orbit. That is to say, it is clear North Korea do not have the 2nd technology to develop ICBM.

CIA under the Clinton Administration did prospect ICBM in North Korea can be closely completed in 2015. Especially, having estimated that the development of ICBM tipped with mini nuclear warhead does take time regarding to the lack of technological ability and financial resources.

In contrast with Clinton period, it is foolish mention, CIA and the Bush Administration did insist North Korea has nuclear weapons already and ICBM as well without any understanding evidence. There might be more behind. Then why do they say so?
