It was very much a moment of high drama. Barack Obama, fresh from his history-making stint hosting the UN security council, took a break from his duties at the G20 economic summit in Pittsburgh to announce the existence of a secret, undeclared nuclear facility in Iran which was inconsistent with a peaceful nuclear programme, underscoring the president's conclusion that "Iran is breaking rules that all nations must follow".
Obama, backed by Gordon Brown and Nicolas Sarkozy, threatened tough sanctions against Iran if it did not fully comply with its obligations concerning the international monitoring of its nuclear programme, which at the present time is being defined by the US, Britain and France as requiring an immediate suspension of all nuclear-enrichment activity.
The facility in question, said to be located on a secret Iranian military installation outside of the holy city of Qom and capable of housing up to 3,000 centrifuges used to enrich uranium, had been monitored by the intelligence services of the US and other nations for some time. But it wasn't until Monday that the IAEA found out about its existence, based not on any intelligence "scoop" provided by the US, but rather Iran's own voluntary declaration. Iran's actions forced the hand of the US, leading to Obama's hurried press conference Friday morning.
Beware politically motivated hype. While on the surface, Obama's dramatic intervention seemed sound, the devil is always in the details. The "rules" Iran is accused of breaking are not vague, but rather spelled out in clear terms. In accordance with Article 42 of Iran's Safeguards Agreement, and Code 3.1 of the General Part of the Subsidiary Arrangements (also known as the "additional protocol") to that agreement, Iran is obliged to inform the IAEA of any decision to construct a facility which would house operational centrifuges, and to provide preliminary design information about that facility, even if nuclear material had not been introduced. This would initiate a process of complementary access and design verification inspections by the IAEA.
