The great leader Kim Jong Il is a peerlessly great man who illuminated the road ahead of the times with his energetic ideological and theoretical activities.

He clearly indicated the way for the victory of socialism by proving its scientific accuracy, validity and truthfulness.

Between the late 1980s and the early 1990s, socialism collapsed and capitalism revived in some countries and it posed a grave challenge to the socialist cause, the independent cause of the masses of the people.

Availing themselves of this opportunity, the imperialists and reactionaries of history talked loudly about the "end of socialism".

This caused a great disappointment, uneasiness and apprehensions of the progressive humanity.

A lot of people were floundering without understanding the truth of the situation.

Kim Jong Il conducted energetic ideological and theoretical activities for defending and victoriously advancing the socialist cause to cope with the tragic situation arising on the world political arena.

He made public famous works including "Socialism Is a Science", "Abuses of Socialism Are Intolerable", "The Historical Lesson in Building Socialism and the General Line of Our Party", "On the Fundamentals of Revolutionary Party Building" and "Giving Priority to Ideological Work Is Essential for Accomplishing Socialism", clarifying the cause of the collapse of socialism in some countries and lesson drawn from it and providing a new milestone for the reconstruction of the socialist movement and its development.

He gave a blow to the sophistry of the imperialists and renegades of socialism with his clairvoyant wisdom and scientific reasoning.

And he systematically expounded the scientific accuracy and truthfulness of socialism and the inevitability and scientific path of its final victory with his profound logic and gem-like propositions, thus providing a powerful ideological and theoretical weapon to defend the socialist cause to the end.

His works served as the banner of hope and struggle that gives confidence in sure victory of socialism to the Korean people and the world revolutionary people, opposes imperialism and dominationism and leads the socialist cause to victory.

The historic Pyongyang Declaration "Let Us Defend and Advance the Cause of Socialism" was adopted and made public in Pyongyang in April 1992 with full support and approval of the representatives of 70 progressive political parties in the world.

Many other progressive political parties of the world signed the Pyongyang Declaration soon after its adoption.

As the Pyongyang Declaration was adopted, the world socialist movement could enter a new era and the revolutionary parties of the world vigorously struggle for the final victory of the socialist cause with a common fighting programme.

The immortal exploits of Kim Jong Il will shine forever as he clearly showed the way for the victory of socialism to the progressive humanity.
