In his book, Bhatia writes that Bhutto brought up the North Korea visit during a discussion in 2003 about her difficulties with Pakistan's military. "Let me tell you something," she declared, before telling Bhatia to turn off his tape recorder. "I have done more for my country than all the military chiefs of Pakistan combined."
At the time, Pakistan was in desperate need of new missile technology that would counter improvements in India's missiles. Bhutto said she was asked to carry "critical nuclear data" to hand over in Pyongyang as part of a barter deal.
"Before leaving Islamabad she shopped for an overcoat with the 'deepest possible pockets' into which she transferred CDs containing the scientific data about uranium enrichment that the North Koreans wanted," Bhatia writes. "She implied with a glint in her eye that she had acted as a two-way courier, bringing North Korea's missile information on CDs back with her on the return journey."
My main question is, why would Bhutto herself be doing this? Pakistan has a very capable and very active secret service, and Bhutto was an elected politician.
