abducted Japanese nationals in the 1970s, as it had been categorically and fiercely denying for many years that the abductions had ever taken place and dismissing rumors of North Korean involvement as an allegedly "racist fantasy." Some of the recent drop in membership of Chongryon is thought to be attributed to ordinary members of Chongryon who had believed the party line feeling deeply humiliated and disillusioned upon discovering that they had been used as mouthpieces to deny the crimes of the North Korean government.
