Secretary of State Clinton recently observed in a media interview that Iran has no right to a full nuclear fuel cycle that includes enrichment and re-processing.  Unfortunately, she misspoke.

Like other countries, Iran is entitled under the Nuclear Non-proliferation Treaty (NPT) to use nuclear energy for peaceful purposes, and that right has long been understood to encompass enrichment under safeguards.¹ Nothing in the NPT or Iran's Safeguards Agreement supports the notion that a country is barred from enriching uranium if it has ever pursued a weapons program, even one halted years ago.

If Iran is willing to honor its legal responsibilities under its Safeguards Agreement and the NPT, there is no principled basis for denying Iran right’s to enrich or demanding that Iran permanently cede that right.
