Talk about bad timing. Before Kim Jong-il’s sudden death, the U.S. was reportedly on the verge of a landmark deal with in which North Korea would receive a large donation of food aid in exchange for that nation halting its uranium-enrichment program. An Obama administration official who spoke to CBS News says that deal is now in danger of falling through in the midst of a likely succession struggle. The two nations have been in secret talks for months, according to the report. Now Obama must deal with a newly tense situation on the Korean Peninsula, where 28,000 U.S. troops are station south of the North Korean border.
