What in the world is the Bush Administration up to? They just can't want to invade Iran. I know they have the most optimistic possible take on military actions, but they just can't think they the US is capable of taking on Iran in addition to everything else on its plate.
Some have suggested that they are setting up the case for Iran ruining the Iraqi occupation: "Iran is the reason Iraq didn't work out". This seems possible, but I suspect something else is going on here.
