Nah, we're not upset at Iran because they're a bunch of expansionist revolutionary fundametalists trying to build nuclear weapons. We're upset at them because our Secretary of State was jilted by an Iranian in college:

Perplexed by the vitriol of US Secretary of State Condoleezza Rice's attacks on Iran, one lawmaker believes he has uncovered the secret of her enmity -- that she was spurned by an Iranian boyfriend at college.

"The reason that the US secretary of state attacks Iran is because she had her heart broken by a young man from Qazvin while they were students," a confident Shokrollah Attarzadeh was quoted by the ISNA agency as saying.

If nothing else, this shows the US has no monopoly on legistators who are so out of touch with reality their shoes don't touch the ground.
