Obama claimed that he was going to talk directly with Iran. Even the French told him that was naive because they had been talking to the Iranians for years and knew that Iran wanted nothing from the West. There was nothing to barter with.
Then the Iranians themselves make Obama look foolish by repeatedly rejecting direct talks.
Ironically, the US has been talking directly to the Iranians through back channels for years without any progress anyway.
The fact is, the Ayatollahs want nuclear weapons most of all and aren’t interested in trading anything.
And when they get one, they’ll use it. It’s their creed.
