After the 9.11 attacks, the international society strengthened its coalition while improving its domestic laws and institutions to face terrorism. Despite these measures, large scale terrorism occurred around the globe in countries such as Indonesia and India. Especially, terrorism in Spain and England shocked the world as it was committed by its own people. These incidents showed the emergence of a new terrorist agent.
The terrorists of Spain and England were second or third generation immigrants who were discriminated and looked down upon in their respective countries. Their frustration erupted to terrorisms. The discrimination and disregard shown to migrant workers, mixed-bloods, and North Korean defectors by Koreans in Korea are not largely different to the cases in Spain and England. The Korean government and society must establish an open policy and attitude to accept them as constituents of Korea. If the Korean society neglects to improve these efforts, the future situations of Korea related to terrorism would not be different to the current situations of Europe.
