Talks between Iran and the P5+1 are being scheduled for next week or the week after. Earlier, Iran suggested Istabul as the venue. Suddenly this week and Iranian official suggested Baghdad as a preferable meeting place. And now Prime Minister Erdogan says
It is necessary to act honestly. [The Iranians] continue to lose prestige in the world because of a lack of honesty.Oops.
This may have something to do with the unrest in Syria, where Iran backs the Assad regime. Or it may be something else. Not a good sign for the negotiations.
Update (4/8/12): The Iranians are willing to accept Istanbul for talks. Today, anyway. Hard to say what this means, but it's probably better than their insisting on Baghdad.
