There will need to be a way to finally incent Iran to make a different choice concerning its nuclear ambitions, but this was not an effort to develop a common strategy. It was really the first large meeting. We had an informal consultation in Sharm el Sheikh, but I think what really did come through here is that these are countries who have really deep interest in how this issue gets resolved, and they want to continue consultations with the P5+1 on how this is all going to come out.
Meanwhile, Iran had already come out with a statement rebutting Rice's "baseless allegations" and "put[ting] on display the ill-intended policies of the United States in distorting the realities about Iran's peaceful nuclear program" BEFORE Rice spoke at the microphone. Having dutifully listened to confirm that, yes, Rice said exactly what the Iranians thought she would say, the Iranian press officer cheerfully distributed his mission's response to the assembled journalists.
In other words, everyone said exactly what everyone knew they would say, then departed with no outcome. I believe this is what John Bolton refers to as "diplomacy for diplomacy's sake."
