Bolton spawned controversy when, in a 2003 speech cleared by the State Department,  he described North Korean leader Kim Jong-il as a "tyrannical dictator" and saying that, for North Koreans under Kim's rule, "life is a hellish nightmare."  In response, a North Korean spokesman said "such human scum and bloodsucker is not entitled to take part in the talks."  Congressional Democrats argued that Bolton's words at the time were undiplomatic and endangered the talks. Bolton later wrote that he had been looking for a "hammer" to "shatter" the Clinton Administration's 1994 Agreed Framework with North Korea, an implement he found when the country's uranium enrichment program came to light.  Critics argued that Bolton's record of allegedly politicizing intelligence would harm . credibility with the United Nations.  President Bush said he wanted John Bolton because he "can get the job done at the United Nations."  Bolton recalls that his 'happiest moment at State was personally 'unsigning' the Rome Statute ,' which had set up the International Criminal Court .
