Does Professor Muhammad Sahimi really challenge assumptions about Iran's nuclear program? The Real News Network aired a revealing statement by this Professor of the University of Southern California, a member of the Union of Concerned Scientists.
"Iran wants to put itself in a position such that if an international crisis arises and there is an external threat to the national security of Iran, Iran can be in a position to make a nuclear weapon in an emergency as a deterrent against a foreign threat. Otherwise, Iran has no intention whatsoever of making a nuclear weapon, because Iranian leaders are fully aware that if they cross the line and somehow they make nuclear weapon, that will start a very bad nuclear arms race in the Middle East, which will ultimately will not be in Iran's benefit or in any body's benefit in that region."
This is clearly something else than what Iran actually claims.
