This paper attempts to analyze the case of past liquidation in Romania’s ‘execution model’ with two dimensions: investigation and reflection on past problems. Like other former communist countries in Eastern Europe, Romania has transformed into a democracy. Despite the 42 years of the Romanian communist regime between 1947 and 1989, the past liquidation mainly focused on the 25-year dictatorship of Ceausescu’s iron-fist, which was dependent on the secret police called Securitate. Once democratized, Romania's past liquidation was implemented in two aspects: past investigation and past reflection. The past investigation was conducted in the form of executions during the December 1989 Revolution. Ceausescu, his family, and his aides were heavily sentenced, including death and life imprisonment in the military trial. However, most Securitate agents received no punishment. The Romanian government has implemented very limited legal measures to compensate or remedy victims' honor. Past reflections have progressed even more slowly. This is because the National Salvation Front, the main revolutionary force, served as a sidekick to the formal communist regime. A criminal investigation body was only set up in 2006, 16 years after democratization. Romania’s lack of decisive judgments and limited systematic past reflection still remain a heavy legacy in social turbulences in Romania. It will have significant implications for the policy of Korean unification in the future.
