Bush adviser: Iran giving same act over nukes

A national security adviser to President George W. Bush said on "CBS This Morning" Thursday that Iran's boasting of advancements in its nuclear program and subsequent renewed interest in negotiations over it represent "the kind of conciliation and tough talk that we've seen from Iran before."

Stephen Hadley told Charlie Rose that Iran, which the United States and others say is pursuing a nuclear weapon, has been hampered by multiple rounds of economic sanctions but doesn't want to be seen as weak.

"It's pretty clear that the sanctions are having a bite," said Hadley. "It has pushed the Iranian currency down dramatically, and I think that accounts for Iran's indications they're willing to return to some conversations about its nuclear program.

"Of course, Iran doesn't want to show weakness, so at the same time they say they're coming back to talk they talk about the progress the nuclear program has made and their willingness to cut off some of their European customers who've been involved in the sanctions, so it's the kind of conciliation and tough talk that we've seen from Iran before."

Hadley doubted whether returning to the negotiating table with Iran would have any effect considering the country's firm stance against giving up its nuclear program and the Western powers' demand that Iran shut it down.

"While the talking makes people feel good, the real question is, is it going to lead to a solution," said Hadley, "or is it just really an effort by Iran to shed some of the pressure and buy some time as it moves forward with its program."
