The International Atomic Energy Agency inspectors are a wonderful example of how important it is to work through the United Nations and its agencies to get people on the ground to investigate situations, in that what they have been able to find when they were able to make inspections has been a treasure trove of information about Iran's nuclear program. It has been much the same experience with the human rights inspectors sent to Iran, by the way, who found a great deal more information than we had otherwise.
Unfortunately, Iran is cooperating less and less with the International Atomic Energy Agency. It now is probably not even fulfilling the absolute minimum requirements. There's a dispute between Iran and the International Atomic Energy Agency about whether or not Iran is fulfilling the absolute minimum requirements, and I do mean minimum, for these inspections.
Whereas previously Iran better understood that openness did much to dispel concerns and was leading us towards some confidence that we had a handle on or an understanding of what Iran's program is like, now there's a lot of concern that Iran may in fact be trying to hide some covert activities and develop some capabilities similar to what it did during the 18 years before 2003, when, it is now acknowledged, it was doing things covertly.
