Obama anticipates Iran's response when tested "will not prove meaningful"...

The Cable, here

"As Undersecretary of State for Political Affairs Bill Burns arrived in Frankfurt for the next round of international talks on Iran's nuclear program, news reportsTuesday suggested Iran's President Mahmoud Ahmadinejad plans to respond to the Western offer for nuclear talks during a speech at the U.N. General Assembly due to take place the week of September 21 in New York.

Diplomatic sources tell The Cable that the Obama administration has recently said it saw signs that the Iranian government plans to issue some sort of response to the West's offer to engage on its nuclear program. But, diplomats said, the Obama administration anticipates that the response when tested will not prove meaningful, and is likely at most to only stretch for a short time an anticipated effort to start pushing for "big bang" international sanctions in the coming months targeting Iran.......

Burns is attending the talks accompanied by aide Elisa Catalano, a former aide to Iran hand Dennis Ross who is now serving as a liaison in Burns's office to the NSC...

"We hear rumors of a possible Iranian signal even before the Frankfurt P5+1 meeting" Wednesday, one Western diplomat said on condition of anonymity Tuesday. "State and NSC expect something from the Iranians at the U.N. General Assembly. But it won't be enough. They don't know what it is, but they do not expect the Iranians to be as stupid as to not reply at all. They are smart enough to do something, to try to stretch the process a bit more."
