Analyst: Iran-US Talks Impossible Without Perceptual Shift

An agreement with America is not possible, as long as dialogue with the US government is considered an "ideological defeat" and neither side is ready to offer concessions, a political analyst says. 
"Some in Iran regard talks with the United States as a compromise as well as an ideological retreat and defeat. As long as this view persists, a win-win negotiation is not possible," Mehdi Motahharnia, a university professor, told ISNA in a recent interview. 
Tehran and Washington cut diplomatic ties shortly after Iran's Islamic Revolution, which overthrew the US-backed shah in 1979.
