Iran's offer: "Support us, and you can get nuclear technology from us if you want."
There must be a ton of additional carrots in the US offer to match the Iran's offer, especially when other Arab states are moving in nuclear direction on their own (Egypt, Syria, who knows who else?) And there is Israel too.
Turn the entire middle east into a radioactive dead zone for at least a century — or else that region will not only never have peace, but those religious fanatics will export nuclear war worldwide.
