All this changed in August 2002, as a series of revelations by an Iranian opposition group forced the Washington establishment to revise its previous intelligence assessments. It suddenly appeared that Iran had not only constructed a sophisticated uranium enrichment capability but was also busy developing a plutonium route to nuclear power. Even more ominous was an indication that Tehran's program was reaching the point of self-sufficiency. Although at various stages, Iran's nuclear industry has benefited from external assistance, particularly from Russia, and even more ominously, from the Abdul Qadeer Khan network in Pakistan, the sophisticated nature of these facilities revealed that Iran might have reached the point of self-reliance, at which traditional counterproliferation measures, such as more export controls and curtailment of external assistance, could not measurably slow down its nuclear timeline. Former President Rafsanjani has confirmed, "That we are on the verge of nuclear breakout is true." Ali Akbar Salehi, the former Iranian representative to the International Atomic Energy Association (IAEA), similarly stressed, "We have found the way and we do not have any scientific problems."
