I remember myself how, in 1991, several inspections in Iraq, which were based on information received from a Government, helped to disclose important parts of the nuclear weapons programme. It was realized that an international organization authorized to perform inspections anywhere on the ground could make good use of information obtained from governments with eyes in the sky, ears in the ether, access to defectors, and both eyes and ears on the market for weapons-related material. It was understood that the information residing in the intelligence services of governments could come to very active use in the international effort to prevent proliferation of weapons of mass destruction. This remains true and we have by now a good deal of experience in the matter.

International organizations need to analyse such information critically and especially benefit when it comes from more than one source. The intelligence agencies, for their part, must protect their sources and methods. Those who provide such information must know that it will be kept in strict confidence and be known to very few people. UNMOVIC has achieved good working relations with intelligence agencies and the amount of information provided has been gradually increasing. However, we must recognize that there are limitations and that misinterpretations can occur.
