When Iran's new president, Mahmoud Ahmadinejad, called last week for Israel to be "wiped off the map," he raised fears not only abroad but also at home, particularly among Iran's sizeable, democratically minded middle class.

Western powers have a dual challenge: to find a way to engage this population even as they struggle to address the new president's inflammatory rhetoric.
