The above synopsis of Iran is excellent, but extremely disorienting at first because the people in it, like Barbara Slavin, Steven Kinzer (author of 'All the Shah's Men') and Trita Parsi, all actually know what they're talking about. They openly mention the Algiers Accord, and I'm so used to viewing propaganda that I got motion sickness and had to dig through cupboards for the dramamine.
Iran lies between Russia, Pakistan, India, China, and the Arabian oil fields. It's going to be self-determined, and it wants democracy. Militarily, this should be a no-brainer: wooing Iran is the only thing that makes sense. The US will open negotiations with Iran as soon as the B.A. is out of the way.
