suprisingly when i was in IRAN one year ago, we meet there more people who like US then they hate US. We didnt met anyone who support the religious goverment (but we spoke mainly with young people only)
There were even one iranian sociologist arrested few months ago for publishing his research, which shows that around 80% of inhabitants of Teheran like US.
Go to make similar research at Saudi Arabian, "big friend" of USA
The religous goverment which leads country is seriously fucked, but the most people there has bigger sense for democracy then all inhabitants of arabian countries (Iran has only small arabian population).
