There is no easy way out of the Iranian nuclear dilemma. Iran, emboldened by the situation in Iraq and soaring oil prices, and animated by a combination of insecurity and assertive nationalism, insists on its right to develop full nuclear fuel cycle capability, including the ability to enrich uranium.
But EU-led diplomacy so far has failed to persuade Iran to forego its fuel cycle ambitions; the UN Security Council seems unlikely to agree on sanctions strong enough to force it to do so; and preventive military force is both a dangerous and unproductive option.
Two possible scenarios remain, however, for a negotiated compromise. The first, and unquestionably more attractive for the international community, is a "zero enrichment"
option. The second is the "delayed limited enrichment" plan spelt out in this report.
