Another factor influencing Bush’s decision to resume Hawk Engagement was the simultaneous election of Yi Myung-bok as president of the ROK. During Yi’s campaign, he spoke for his party and a growing number of South Koreans in criticizing the “Sunshine Policy” and advocating a tougher approach toward North Korea. Upon assuming office, Yi demanded that the DPRK take real steps toward nuclear disarmament as a condition for receiving further assistance from the ROK. Relations between the Koreas experienced a rapid deterioration, as Pyongyang demanded that South Korean firms evacuate the jointly operated industrial village at Kaesong.92 However, in May 2008, Pyongyang attempted to satisfy Bush’s demands when it provided seven boxes of documents detailing its three separate efforts—in 1990, 2003, and 2005—to develop a nuclear weapon. The Bush administration registered dissatisfaction because this information failed to confirm its claims about the extent of the DPRK’s nuclear activities.93 Despite the DPRK’s destruction of the cooling tower at Yongbyon in June, the United States demanded that North Korea provide documents confirming its HEU program and the export of nuclear technology. The DPRK responded that it could not produce what did not exist, insisting upon prompt delivery of all the fuel oil promised in return for providing full information on its nuclear programs. It also announced that it was halting dismantlement of nuclear facilities until the United States fulfilled its commitments.94
