US and Iran: Is an Iraq grand bargain possible?

The Real News Network's Paul Jay talks to Gareth Porter about Iran, Iraq and the Bush administration. One of the fundamental reasons The White House is giving for a possible attack on Iran is that it is arming Iraqi militias that are killing American soldiers. The administration and the US military first began to talk about Iran as a source of weapons in 2005 but have yet to present concrete evidence to back the charges. Complicating matters is the fact that both Iran and the US support Iraq's al-Maliki government at the same time. While the White House hints at a possible attack on Iran, the US military talks about a deal over Iraq. But what kind of deal could it be?
