I wonder if obama would reason out that Iran was insulted that the US sent a woman.
IRNA reports:
After the first round of negotiation wrapped up its work, the Iranian delegation met separately with Turkish Foreign Minister Ahmet Davutoglu, Russian Chief Negotiator Sergey Riabkov and the EU Chief Foreign Policy Catherin Ashton.
Catherine Ashton is a woman so it looks like a clear snub to Obama.
