Calling it “the best option in a bad situation,” Geoff Forden and John Thomson have another paper out recommending a multinational nuclear arrangement to resolve the crisis over Iran’s nuclear program:

Iran would lease all its enrichment-related equipment and facilities to the partnership and would undertake not to enrich and reprocess except through the partnership.

The partnership would also lease URENCO centrifuges and install them in batches, the first in a few months, the last (making a total of, say, 50,000) seven or more years later. Until the first batch comes in to operation, the partnership would use Iranian P1 centrifuges; all of which would be phased out as soon as the URENCO centrifuges begin to operate. (We estimate that in this period the existing P1s could not produce enough HEU for a weapon.) To preserve secrecy, the sensitive parts of the P1’s would be “black boxed” and handled only by Iranians;

I think MNAs are a promising route to move beyond safeguards in providing confidence that states remain in compliance with their nonproliferaiton options … although I have my doubts about whether the Iranians would take this deal.

Anyway, I thought I would put together a little bibliography on MNAs.
