This entire exercise was doomed before the parties sat down. The "Powers" came to Baghdad to squeeze, not negotiate. And even if the Powers had a mind to budge even an inch to offer the Iranians some way to emerge with some dignity, Bibi and the US Congress were waiting to smack them down.
Netanyahu/AIPAC/The Lobby/CUFI have Obama and Congress by the balls - and are determined to neuter Iran.
This may have been the last shot to avoid war. But Danica-lovin' Joe Sixpack has already consigned to that old dustbin the thousands of American lives lost and ruined - and the hundreds of thousands of Iraqi lives lost and ruined (not that he cared especially) - to the Iraq debacle. No doubt, he sees Iran as ready to crumble under a barrage of Cruise missiles and US Navy bombers. No Americans in real jeopardy that way - and besides, Jesus and the Fox News experts don't care about dead Muslims. Jesus wants the USA to reign forever. Dead foreigners just got in the way.
