Iran talks end in harsh lesson for west
The Iranians are suicidal, and the politicians from the other involved nations and regions are fools.
The Iranians are successfully stalling until such time as they are able to field nuclear weapons, and the western leaders know this.
The only reason they allow the stalling (besides being weak willed, limp-wristed pansies) is political expedience.
They want to be seen as peacemakers, and are fearful of political ramifications from their various electoral bases if any sort of military action is taken.
Meanwhile, Iran's nuclear program accelerates.
