Iran has a population of about 70 million. Ten percent of them are as nutty as the current leadership, i.e. U.S. is the Great Satan...yada yada yada. Due to a combination of apathy and fear, the 63 million aren't going to challenge the 7 million Islamic nutcases without external military support. Same issue as Saddam's ability to stay in power in Iraq despite being part of a minority there. You'll also find it is the reason that Castro still has his head attached to his body. The majority live in fear of the zealot minority in control of the regime.
Since seven million of the little darlings (I am sure some are women and children) hate us to the point of killing us if they could, we might as well surrender now.
Should we start learning Iranian or Chinese? I hate these choices.
For those of you in Rio Linda, the foregoing is based on the "Yellow Striped" call of the Great American Chicken when "There are too many of them to do anything else!"
