Rodong Sinmun Saturday says this in a signed commentary.

The PSI cooked up by the U.S. is a brigandish mechanism for a war of aggression as it is designed to check and inspect ships or planes, etc. of any country suspected of carrying nuclear weapons or missiles and other WMDs and the DPRK is made its main target, the commentary notes, and goes on:

The Lee group openly joined its American master in his criminal scenario by declaring its full participation in the PSI. This is the thrice-cursed act of treachery as it endangers the destiny of the nation by blindly following outside forces in disregard of the sovereignty and dignity of fellow countrymen.

The DPRK never compromises with those who infringe upon its sovereignty, refusing to recognize it and ignoring it, but settle accounts with them to the last.

It is ridiculous, indeed, for the Lee group to dare challenge the DPRK's sovereignty by fully participating in the PSI in reliance upon outside forces' "strength."

Unimaginable are the catastrophic consequences to be entailed by the above-said action of the group. It may spark off an armed conflict and an all-out war any time.

The Lee group will be wholly accountable for the above-mentioned disastrous consequences as it has followed foreign forces in utter disregard of the DPRK's sovereignty and dignity.
