The success in the explosion test of a smaller and lighter A-bomb makes it possible for the country to bolster up its physical deterrent capable of foiling any aggression moves of the enemies at one blow.

The nuclear deterrent that has been bolstered up represents a just cause for defending the security and sovereignty of the country and nation as it is part of the practical measures taken by the DPRK to cope with the U.S. hostile policy toward it.

For over half a century since early in the 1950s the U.S. has turned south Korea into the biggest nuclear arsenal in the Far East, gravely threatening the DPRK through ceaseless maneuvers for a nuclear war. It has worked hard to deprive the DPRK of its sovereignty and its right to exist and develop publicly recognized by international law, thereby doing tremendous damage to its socialist economic construction and the improvement of the standard of people's living.

The U.S. found fault with the DPRK's satellite launch for peaceful purposes while shielding the south Korean puppet forces' satellite launch. Such application of double standards is seriously hindering the DPRK's development.

The U.S. hostile policy toward the DPRK is increasing the danger of a war on the Korean Peninsula day by day and putting global peace and security at peril.

All facts prove that the DPRK's measure to bolster up its nuclear deterrent is the most just step for shattering the aggression moves of the U.S. and defending peace and security on the Korean Peninsula and in Northeast Asia and, furthermore, in the rest of the world.

The U.S. and its allies are vociferating about international "reaction", again taking issue with the DPRK's underground nuclear test as a "provocation".

With no desperate efforts can the U.S. shake the faith and will of the army and people of the DPRK and their resolution to wage a battle against the U.S. and wipe out enemies.

The DPRK will firmly defend the security and sovereignty of the country and nation from the U.S. hostile policy and arbitrary practices.
