Gates:"No grand bargain" with Iran

US Defense Secretary Robert Gates said Tuesday there is "no grand bargain" with Iran as the United States tries to bolster relations with the Teheran government.
Asked by reporters what kind of progress the US is hoping for with Iran, Gates said he didn't know what was possible.
The US is still waiting to see how the Iranians respond to President Barack Obama's outreach, Gates said, but so far the rhetoric from Iranian President Mahmoud Ahmadinejad has been "not very encouraging."
