In testimony before Congress on Thursday, a leading nuclear expert insisted that contrary to what a Pakistan Foreign Office spokesperson had said, the case against Dr AQ Khan was “far from closed” and many questions, especially about Iran, remain unanswered. The hearing, held by the subcommittee on international terrorism and non-proliferation, received testimony from, among others, by David Albright, president of the Institute for Science and International Security (ISIS). The hearing, which mainly featured the AQ Khan network, was hurriedly arranged, not having been on the concerned congressional subcommittee’s announced schedule, and should be seen as the beginning of a pressure-building process vis-a-vis Pakistan. The recent Pakistan Foreign Office spokesperson’s statement that the case against Dr Khan was now closed and all important information had been gathered and shared, was received with surprise in Washington and viewed negatively, with some in the administration and Congress interpreting it as a counter-pressure tactic against the United States.
