Behind scuttled nuke pact, Iran’s regime in turmoil

In the wake of news that Iran tested a long-range missile yesterday, as reported by PRI’s The World, questions have intensified about internal political turmoil in Tehran. Ray Takeyh of the Ploughshares-funded Council on Foreign Relations provides a new perspective on what was behind Iran's recent decision to backtrack on agreements with the West about its nuclear program.  Interestingly enough, writes Takayh, it was Iranian President Mahmoud Ahmadinejad who promoted the low-enriced uranium deal in order to have a foreign policy victory to show at home.  Internal politics forced him to reverse himself, and he once more reverted to his earlier, strident rhetoric about the nuclear file being closed.
