Revelations from the 2004 exposure of the A. Q. Khan network have highlighted the importance of this region in global nonproliferation efforts. While terrorism is by no means constrained to the Afghanistan/Pakistan border, the confluence of intent, knowledge and materials is found in this region. It remains uncertain if all nodes of the Khan network have been identified. Other leading Pakistani scient ist s have demonstrated a willingness to share nuclear knowledge if not material capabilities. The diversity of suppliers in quantity, location and specialty has made confirmation tentative at best. Pakistan’s nuclear weapons program is extensive and ongoing. The infrastructure that enabled Khan’s prolonged success remains in place. In addition, the intentions of individual members of Pakistan’s intelligence and military leadership have been called into question as a result of revelations regarding Bin Laden’s death.
