The New York Review of Books in its March 20 issue publishes a paper by William Luers, Thomas R. Pickering, and Jim Walsh that proposes a plan for creating a multinational enrichment facility in Iran, along with statements from senators Dianne Feinstein and Chuck Hagel endorsing the plan. In short, the idea is that
"the Iranian government would agree to allow two or more additional governments (for example, France and Germany) to participate in the management and operation of those activities within Iran."
This is similar to the plan proposed by Geoff Forden and Sir John Thomson some time ago, the apparent difference being that the new proposal does not seem to include an offer to supply high-performance centrifuges to Iran.
RIA Novosti reported that Iran's UN envoy spoke favorably about the idea of inviting other countries to join Iran in its enrichment activity, but his statement, apparently made at a meeting with journalists on Monday, was not reported by anyone else.
It is unlikely that Iran would agree to the plan as it is outlined in the NYRB article. However, the authors are right - a proposal like this is the best chance to resolve the situation.
Ahmadinejad said this during his UN speech on Sept 17 2005:
Other proposals by Iran were listed by Javad Zarif in the International Herald Tribune in April 2006:
This is a deliberate plan and policy of regime change through force. These are just the preliminary steps in what is a pretty obvious trend.
