Recently declassified state documents of the U.S. revealed the fact that it planned a nuclear attack on the DPRK in 1969 when EC-121 large spy plane incident occurred.

At that time the U.S. Defense Department worked out a "plan for attacking 12 places of north Korea with 0.2-10kt nuclear weapons", a "plan for attacking 16 airfields with 10-70kt nukes to destroy air force of north Korea" and a "plan for disabling the majority of the offensive capability of north Korea" in "retaliation" against the resolute self-defensive measure taken by the DPRK and submitted them to the White House.

According to those documents, the U.S. had worked out a plan to mount nuclear attacks on the DPRK and several areas of Northeast China in 1954, the year right after the end of the Korean War.

This is another testimony that the U.S. has always watched for a chance to use nuclear weapons against the DPRK, pursuant to the "policy of strength" toward it.

This indicates that the present U.S. administration is nothing different from the preceding regimes in their policy of nuclear threat to the DPRK as it excluded the DPRK from the list of non-use of nuclear weapons in the "Nuclear Posture Review" in April.

Historical facts prove that the DPRK was quite right when it made a decision to react to nukes with a nuclear deterrent.

The recent disturbing development on the Korean Peninsula underscores the need for the DPRK to bolster its nuclear deterrent in a newly developed way to cope with the U.S. persistent hostile policy toward the DPRK and military threat toward it.
