The present study aims to explore how fallacies, arguments that seem valid but are not, appear in 2022 South Korean presidential debates. It qualitatively analyzes the candidates' remarks in the first and last presidential debates (240 minutes) using 20 formal and informal fallacy concepts as a theoretical framework. Results show that the three candidates used 23 informal fallacies from 15 categories, including the straw man, red herring, begging the question, complex question, hasty generalization, appeal to the masses, and you too. The candidates relied on fallacies to defend their image and electoral agenda from adversary attacks and to contaminate their opponent's image and agenda. The arguers, who struggled with tough questions, frequently made fallacies as pseudo-arguments to avoid the situation without lying and violating election laws. This study indicates that the fallacy system can be a framework for analyzing crucial political content. Moreover, it warns against the abuse of fallacies in TV debates.

This article presents a descriptive analysis on national security policy platforms promoted by the ruling parties of South Korea during general and presidential elections. National security platforms made during the elections campaigns are a window that allows us to see how the ruling party perceives the threat environment, opportunity-structures, policy preferences and material capabilities faced by the state. South Korea presents a unique case since it faces constant military threats from North Korea and interacts with China and the United States. Therefore, the national security policy platforms, which are explicitly campaigned during the general and presidential elections, showcases the worldview of the ruling party. The study essentially focuses on three areas of the platforms - its threat perception on North Korea, the ROK-US alliance and the future vision for the Korean peninsula by covering two presidential elections and three general elections for the last 20 years.
