I wouldn't rule that out. The Iranians are just dragging things out. They are rug merchants. I lived in Iran for a few years and know how they negotiate. They like to take you right up to concluding a deal and then change the conditions at the last minute in hopes that your eagerness to stike a deal will result in some last minute concessions.
I repect you experience and opinion. Thanks for your perspective. It will be "interesting" to watch.
Thanks for the insight. It begs the question of why the press fails to understand and report this? So quick to jump to conclusions against our side, they seem to fall flat in evaluating others.
