I honestly don't know what the deal is with Shahram Amiri, but this Economist analysis of the Iranian nuclear scientist's strange quasi-defection/kidnapping/repatriation grabbed my attention:
How did Mr Amiri turn up at Pakistan's embassy, then? It seems unlikely that the 32-year-old physicist escaped from the CIA. This leaves the possibility that America is seeking some kind of swap. Perhaps having extracted as much as was feasible from Mr Amiri, they are allowing him to claim that he was kidnapped in order to protect his family back in Iran. If he is allowed to leave the country, America might seek the return of three American hikers Iran has been holding for a year. Iran says they are spies.If some kind of swap takes place, the truth may never emerge. Typically, both countries involved stick resolutely with their story: that they are kindly releasing foreign spies in exchange for their innocent citizens held abroad. But if there is no talk of a swap in the works, an awkward stand-off lies ahead. Mr Amiri cannot leave Pakistan's embassy and American territory without American permission. That would further heighten the tensions between America and Iran. The case of Mr Amiri, like the recent exchange of Russian and American alleged spies, would make for great spy fiction, but the dangerous impasse between the West and Iran over the nuclear issue is all too real.
Take this a step further: anyone still holding out hope for a "Nixon goes to China" moment on Iran better not hold their breath. The Islamic Republic's very rationale for existence hinges, at least in part, on anti-Americanism. It may be too difficult for the regime to dial that back and retain its legitimacy; especially as it faces various challenges to its authority.
Thus, progress mightn't be a photo-op, but small, quiet concessions.
And the West has always talked, traded and done business with this regime in such a fashion - it's hypocritical and cynical, for sure, but it just might be what U.S.-Iranian rapprochement could look like, if ever such a thing were to happen.
UPDATE: The Post has a good summary of this odd story.
