The letter said:

I want to begin with the conclusion that the letter addressed by the under secretary-general for Political Affairs is not the answer to my question on what is the legal ground for the UN Security Council "sanctions resolutions" against the DPRK over its nuclear tests and peaceful satellite launch.

In the letters to the former UN secretary-general dated May 23 and December 5, 2016 respectively, I questioned if there is any single article in international laws which stipulates that nuclear tests and satellite and ballistic rocket launches constitute a threat to international peace and security as a legal ground for the UNSC "sanctions resolutions" against the DPRK.

However, the UN Secretariat has only mentioned Article 39 in the UN Charter without any single word in response to my questions.

Article 39 of the UN Charter cannot be a legal ground for "sanctions resolutions" as was already discussed in international law community.

In 1966 when former Rhodesia declared independence from the British colonial regime the UNSC adopted a sanction resolution invoking Article 39 as its legal ground for the first time in the history of the UN. In this regard the international law community asserted that declaration of independence is not a threat to the peace or breach of the peace and labeled the adoption of the sanction resolution as an act of abuse of power. And even the writers of the UN Charter clarified that they had drafted Article 39 referring to an act of aggression, not to be invoked for a sanction in a peaceful time.

If any nuclear test or satellite or ballistic rocket launch were considered a "threat to international peace and security", the UNSC should have made an issue of and enforced sanctions on the United States and other countries regarding their nuclear tests of over 2 000 times, ongoing regular satellite and ballistic rocket launches.

This clearly proves that Article 39 of the UN Charter has no relation with any of nuclear tests or satellite launches.

The acts of fabricating an unlawful and immoral "sanction resolution", imposing sanctions of blockade and going as far as to include in the list of targets of sanctions even sports rifles or bullets and bows and arrows by the UNSC are nothing but an act against humanity and civilization, severely threatening the right to live of our people and destroying the modern civilization as well as making the whole world turn back to the medieval dark land.

The hydrogen bomb test, nuclear warhead test and test-firing of various means of strike including inter-continental ballistic rockets are all full exercise of the legitimate right as stipulated in the UN Charter, as self-defensive measures for deterrent power which can wipe out the source of provocation in case of the encroachment upon our sovereignty and right to existence by the hostile forces.

As long as the United States and its followers keep on nuclear threats and blackmails and as long as they do not stop their war games at our doorstep, disguising them as annual events, our self-defensive capabilities and the capability for preemptive strike with the nuclear armed forces as their pivot will be bolstered significantly.

I hope that the UN Secretariat will discharge its responsibility before the international community by pondering over the questions regarding a legal ground of the "sanctions resolutions" against the DPRK and by responding with impartial answers to them in conformity with the basic mission of the UN for international peace and security.
