In reality, however, Iran is not doing anything that violates its legal right to develop nuclear technology. Under the NPT, it is not illegal for a member state to have a nuclear weapons capability -- or a "nuclear option." If a nation has a fully developed civilian nuclear sector -- which the NPT actually encourages -- it, by default, already has a fairly solid nuclear weapons capability. For example, like Iran, Argentina, Brazil, and Japan also maintain a "nuclear option" -- they, too, could break out of the NPT and make a nuclear device in a few months, if not less. And like Iran, Argentina and Brazil also do not permit full "Additional Protocol" IAEA inspections.
