The former representative of the "Saenuri Party" said "it seems clear that the capability of the north's nuclear weapons is nearing the stage of completion", adding while the north is increasing the nuclear capability, south Korea ended in failure no matter whatever measure it took.

He noted that Park Geun Hye's policies of escalating confrontation with the north including "confidence-building process" came to naught.

The representative of the Minju Party said that when the Lee Myung Bak and Park Geun Hye regimes pursued harsh policies, the north put its nuclear capability on a high level.
