I don't know what to make of this (and it's firewalled) but for the record:
Luckily, the cayenne cloud was largely a smokescreen for what appears to be some real progress in the "full and frank" negotiations. While the talks theoretically were limited to Iraq, they quickly expanded to include other "bilateral issues" code for Iran's nuclear program, which Tehran hopes to use as a trump card for extracting concessions from Washington in Iraq.
Meanwhile, Iran separately and simultaneously agreed to allow the International Atomic Energy Agency to send nuclear inspectors by the end of July to Iran's heavy-water reactor site in Arak. This kind of reactor is valued primarily for its ability to quickly produce large amounts of plutonium, an element that is critical to the production of mushroom clouds. It is no coincidence that Iran is putting up a cooperative front on the nuclear issue just as the Iraq talks move forward.
More important, Iran and the United States now appear to have made enough progress to begin implementing agreements from the May meeting. After the second round of talks, Crocker said the U.S., Iraqi and Iranian governments plan to create a security committee to discuss containing violence in Iraq, addressing everything from "support for violent militias" to al Qaeda to border security.
Translation: The two countries will create a purge committee; the United States will kill any Iraqi Sunnis who do not cooperate, while the Iranians do the same to rebellious Iraqi Shia.
