As for your thesis that Cheney and W have nothing to lose. That may be the case for them, but their is the republican party to be worried about.
As this is being written, Richard Cheney , POTUS
If Cheney for what ever twisted reason decides to go in to Iran, he will have backed every republican congress person into a corner.
Republicans,et al have backed themselves into the corner and need no help from George and Dickie.
The only way they could justify an invasion of Iran is if the Iranian government made some sort of blatant attack. Such as a squadron of Iranian fighters going over to Iraq and carpet bombing Baghdad.
