Without wanting to downplay the seriousness of Iran's nuclear program, this is incorrect on two counts. Firstly, Iran has not enriched to weapons-grade - the highest levels it has gone to is just under 20%, which is still LEU (Low-Enriched Uranium). Secondly, there are other uses for weapons-grade HEU other than weapons - for example, Brazil enriches to weapons-grade to produce fuel elements for its nuclear submarines (HEU is used in naval reactors so that they can be more compact). Iran doesn't have naval reactors, though.
