This is an internal and external approach to the literary works of Kim Kijin who took part in establishing a new country on the ground of anticommunism during the Korean War times. It helps us to understand the gamut of Kim Kijin’s literature, extending Kim Kijin’s literary boundary which had been studied and revolved only around the proletarian literature to that of 1950’s. In this aspect this thesis can be said to be significant and noteworthy. To Kim Kijin the Korean War meant a place where life and death intersected. During the Korean War Kim Kijin went through extreme experience, being tried in the people’s court and almost being executed. Kim Kijin who escaped death after the people’s court by a miracle joined in working on the war literature and developed vigorous writing. It was necessary for him to prove and show that he had nothing to do with the communism under the rule of anti-communism. This made him decide to join the war writers in the army and contribute to the front line media like “Jeonseon Munhak (the front line literature).” He created anti-communism discourse dynamically and vigorously as a subject who led the national ideology during the Korean War. He let his memory of people’s court frequently show up in his works and also let his hateful and degrading sight toward “commies” on purpose. He always put more emphasis on the spirit rather than on the body and held the hostile sight to communism all the way. The pieces of his writing such as war journals or war poem showed and evidenced that South Korea had the dominant position over North Korea. Recognizing that the pen could be a weapon, he intended to comfort people living in the rear and encourage soldiers in the front. Therefore he usually employed the way to illustrate the spiritual advantage of the anti-communism ideology by means of editorials or essays and optimistic outlook for the victory by means of war poem.
