If we hit Revolutionary Guard facilities and those facilities that help the present economy, it's not entirely clear that the under-30 demographic you fear alienating would actually be alienated.

Anecdotal, unscientific evidence: my friend, who is Iranian, protested the Iraq War before it started. She went to visit Iranian relatives in 2004. She expected to hear a lot of support and Bush-bashing. She heard the exact opposite. In her words, "most of my relatives and their friends said that they wished Bush would bomb Iran and kill the ayatollah".

Do you have better evidence that bombing military targets like crazy (as well as political targets like Ahmadinejad and Khamenei - in a war they become valid targets if they are at a location that might otherwise be bombed) would turn the Iranian people against us?
