Since winning election in 2013, Iran’s President Hassan Rouhani has been accorded sympathetic treatment in the foreign press. That his moderation was largely a fictional construct didn’t matter. All that mattered was that Iran had replaced a cartoonlike villain—Mahmoud Ahmadinejad—with someone who could be called a moderate. That was bad enough when it came to whitewashing the regime he fronted before the nuclear talks began. However, Rouhani’s fake identity is crucial to the effort to sell the West on the need to appease Iran by signing a deal that would fail to prevent it from becoming a threshold nuclear power. The key to Iran’s success in the talks is for the U.S. to fall for Rouhani’s pose as the good cop resisting the evil influence of the “bad cop” hardliners.
