Do you think that's a problem? I'd bet we refuel them on the ground in Iraq someplace out of sight. You won't see that in the news though.
After watching us roll up Iraq as fast as we did following Afghanistan, the mullahs won't do anything with the amount of dissent they're facing at home. They're hoping the anti-war protestors will Vietnam any possibility of us doing anything. That along with posturing is the only thing they can muster.
After Bush is re-elected, the mullahs will see the writing on the wall unless they're totally out of touch with reality. Besides North Korea needs another example to "encourage" cooperation. Watching Iran's nuke facility go poof is the best thing to get the little guy's attention.
You aren't taking into account how an attack by Israel would be viewed by surrounding countries. (see #17)
The goal is peace in the Middle East. We don't want to destroy what we've been fighting for in Iraq.
