One of the first actions of President Rohani was to free some political detainees, and
publicly claiming that Iran has no intention to have possession of nuclear weapons.In fact the news reports came out saying Rohani is willing to close down the uranium refining sites in Natanz, Isfahan and Fordo.
This only means that Rohani is seeing the effects of economic sanctions in his country which were imposed by the US and Europe as a punitive act against Iran's nuclear ambition.
The U.S. should not let its guard down. It is Iran who is feeling the economic pinch and all her future actions will be based on easing the burden on her people, but its nuclear program is still running!
It is an oppurtunity for the U.S. to impose demands on normalizing relations between the U.S. and Iran.
Iran wants normalcy more than the U.S. and Israel. It is a golden opportunity fraught with dangers, the world never know and may not know the current state and extent of Iran's nuclear power development program.
