A Study on the Possible TERRORIST Attacks Using Improvised Explosive Device in Republic of KOREA

North Korean refugees have legal citizenship of Republic of Korea, but the South Korean government has re-duced its support policy on North Korean refugees in size and scope. Unsatisfied expectations to South Korean society and a significant gap between the expectation and the real life in South Korea lead some of North Kore-an refugees to criminal activities. For these reasons, some of North Korean refugees fall into a social outcast or criminal offenders due to failure of adjusting to South Korea. In some extreme cases, they may use IEDs, which can be easily obtained and manufactured, as a way of criminal offense to express their anger and frustration to South Korea. This should be taken into consideration. Improvised Explosive Device(IED) is an off-hand manufactured device using destructive, fatal and harmful spark-induced materials or sensitive chemicals. In general, it means homemade bombs and destructor for inca-pacity. Especially, IEDs are commonly used by the vandalist, terrorists, suicide bombers, and rebels. In using the IEDs, ways of manufacturing is quite simple and extempore. Improvised Explosive Device(IED) consists of main charge, initiating system, and casing in general. Main charge is the most important component in explosion, and military ammunition is most preferred. Also, there are cases of blending dynamites or chemicals recently. First, it needs to be explore the tendency of organizing and ferocity of crimes committed by North Korean refugees based on the fact that there is ongoing movement of being collective. It is not totally excluded that they might conduct terrorist attacks on multi-purposed facilities. Thus the countermeasures for the possible attacks should be prepared and management on North Korean refugees’ network should be enhanced. Second, spreading method of making IEDs and selling the law materials to make IEDs through the Internet are reported and committing suicide or damaging others by IEDs are increasing. If North Korean refugees ob-tain or manufacture IEDs and make use of it when committing crime, the effect would be tremendous. Thus, crack downs on illegal trafficking or illegal websites should be implemented nationwide. Thirdly, lack of sufficient settle down programs and employment programs causes failure in adjusting to South Korea, and it leads to terrorism of expressing their anger. Therefore repairing the legal and systemic measures is needed. Lastly, If the collateral damage is inevitable, cooperative measures on IEDs among the related authorities should be built and performed to minimize the collateral damage and social cost and to maximize the effec-tiveness as techniques for terrorist attacks evolved and developed.
