Under the current circumstance US will need to link Iran to Iraq and convince the American people that Iran is responsible for the American casualties in Iraq.
This potential war is not much about WMD's. Iraq had WMD for years and US even supported Saddam. Once Saddam was linked to Al-qaida, even the UN didn't matter.
Perhaps parsi and the other iranians of which you speak were not ones who were able to cast 300 votes apeice in the last election...I also seem to recall that (at least some - if not all) opposition candidates were baned from running (and just prior to the election I think)...
Before Ahmadinejad came to power, the moderate presidential candidates had been disqualified by the so called Guardian Council.
The elections in Iran is a joke. Having said that, Ahmadinejad manipulated people during his presidential campaign. There was no talk of Islamic fundementalism or Israel, but the guy did his U-turn anyway.
Iranians have never been so apathetic towards politics as they are now. They don't want war, because they don't like it and they never have.
Let's just hope all the wise and decent politicians will prevail.
