Rodong Sinmun Tuesday says this in a signed article.

It goes on:

It is the most urgent task facing the Korean nation at present to meet all challenges of the anti-reunification forces and give a strong impetus to the trend of the era of independent reunification under the banner of the June 15 joint declaration.

The moves of the south Korean conservative group to block the advance of the June 15 era of reunification and provoke a war of aggression against DPRK in collusion with foreign forces reached an extremely reckless phase with the case of the warship "Cheonan's" sinking as a momentum.

The prevailing situation urgently requires all the Koreans at home and abroad to resolutely meet the vicious challenges of the anti-reunification forces at home and abroad with the might of the national unity and wage a dynamic movement for national reunification under the uplifted banner of the above-said declaration.

National reunification, the desire of all the Koreans, can be achieved only when the June 15 joint declaration and the October 4 declaration are upheld and implemented.

All the Koreans should never pardon the conservative group's such anti-reunification acts as defiling the inter-Korean declarations and categorically refusing to implement them.

They should roundly expose and denounce the conservative group's treacherous acts of having brought the inter-Korean relations to a collapse.

All the fellow countrymen in the north and the south and abroad should achieve positive solidarity and alliance irrespective of ideology, political view and ism and check and frustrate the puppet group's anti-reunification moves.

Peace is achievable only through a bold struggle to smash the moves of the warmongers at home and abroad to escalate the confrontation and start a war.

The difficulties the Korean nation is facing in its way of the strenuous struggle for national reunification are temporary, but it is sure to triumph, the article notes, stressing: No force on earth can block the dynamic advance of all the Koreans towards independent reunification, peace and prosperity under the banner of the June 15 joint declaration.
