The current negotiations with Iran are encouraging, if we can take them at face value.  Currently they insist on enrichment as a right due to their participation in the NPT and have said they would agree to more thorough inspections.  Given the past history of the program, I would argue inspectors be placed permanently at Iran’s nuclear sites as a precondition for any form of enrichment.  If Iran is truly honest about its program, they have no reason to decline this demand.  Yet, does the NPT give Iran the right to enrich or merely the privilege of enrichment if they abide by its stipulations.  As the main stipulation is the abandonment of a nuclear weapons program, one could argue they should not use this privilege until they demonstrate their cooperation.  However, if we want to accomplish anything with these talks, we must grant some sort of enrichment capability to Iran or they will abandon the talks and possibly expel all the IAEA inspectors from the country.
