Iran has agreed to let inspectors from the United Nations Nuclear Agency visit its recently rebuilt second uranium enrichment plant. They will go there on Oct. 25th, the day was set during a visit to Tehran by the head of the agency Mohammed ElBaradei. The revelation last month said Iran was building an underground facility near Qom heightened international concern that it's secretly trying to develope nuclear weapons. But Mr. ElBaradei gave an upbeat assessment to relations with Iran. I have been saying for a number of years that we need transparency on the part of Iran. We need co-operation on the part of the international community. So I see that we are at the critical moment. I see that we are shifting gears from confrontation into transparency and co-operation. In Washington President Obama's top security advisor said things appeared to be moving in the right direction.
