As a candidate for president, Barack Obama made diplomacy with rogue regimes a signature issue. “The notion that somehow not talking to countries is punishment to them…is ridiculous,” he declared in 2007. In both his inaugural address and his first television interview as president, he reached out to the Islamic Republic of Iran. “If countries like Iran are willing to unclench their fist, they will find an extended hand from us,” he told Al-Arabiya. In the six years since, whether firebrand Mahmoud Ahmadinejad or reformer-by-comparison Hassan Rouhani held the Iranian presidency, Obama has been so committed to a deal on Iran’s illicit nuclear program that he hasn’t let anything stand in his way—Congress, allies, or even facts.
