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.
Looking to the past as an indication of what might happen now, what was the fallout from Israel taking out Iraq's facility? Did everybody run to the UN and whine and cry? Iran is deathly afraid of us at this point. The "cowboy" from Texas has a reputation of being too quick with a gun.
As far as I know Iran doesn't have a big brother to hide behind. Allah seems to have left the building if you catch my drift. The fundamentalists no matter how thick the calluses on their foreheads seem to be batting zero at the prayer thing. I suspect there's a huge untapped market for anti-depressants in some of those countries.
so far we've racked up Afghanistan, Libya and Iraq with the exception of a few insurgents that have been over exposed by the press. Do you believe the mullahs in Iran haven't noticed?
