The NPT "implies implies the right to use nuclear technology (like enrichment) for peaceful purposes . . ." It seems to me that your use of the word implies shows the weakness of your argument. It may well be that Iran will be allowed to continue low level enrichment, but I am not sure that they have the right to do so under the NPT. If you have sources that say otherwise, you should share them.
