Minju Joson Saturday in a commentary slams this as an unpardonable act of infringing upon the sovereignty of the DPRK.

As recognized by public at home and abroad, space development has become a world trend. That is why many countries of the world are making huge investment in space development. They are vying with each other to launch satellites to get involved in hot competition for conquering space.

It is an unpardonable infringement upon the sovereign right of the DPRK for the hostile forces to pull up the DPRK over its satellite launch.

The U.S. and south Korean authorities must know why the DPRK had access to nuclear weapons while tightening its belt despite difficulties and trials.

Now that the U.S. and south Korean warmongers are becoming all the more pronounced in their moves to stifle the DPRK by force of arms, it is a very just measure for self-defense in every aspect for the DPRK to bolster up the nuclear force both in quality and quantity.

The U.S. should bear in mind that aggressors and provocateurs' ever more undisguised infringement upon the sovereignty of the DPRK would only compel it to ratchet up its counter-action against them.

If the south Korean authorities truly want to join hands with the compatriots in the north and improve the inter-Korean relations, they should properly understand the nature of the situation and act with discretion.
