Iran Update: Enrich and Defuse?

Since Kiko's House is obsessing on Iran this week, it's worth noting that there has been a possibly positive development: Russia has proposed to defuse the confrontation between Iran and the West over its worrisome nuclear program by establishing a joint venture to enrich uranium in Russia.

The devil is in the details of course, and among the unanswered questions is whether the agreement would be merely commercial, which is to say financial, or whether it also would be scientific. Russia had previously offered to produce uranium for a nuclear power plant it is building in Iran on condition that the spent fuel be returned to Russia for reprocessing.
