What is so "extreme" about Iran? Do you mean their religion? Because I don't see Iranian Muslims as anywhere near as extreme as the Saudi Wahabbist Sunnis that make up Al Queda and are causing havoc in Iraq. Iran even helped us overthrow the Taliban in Afghanistan, that were a valid target in my mind and a true "extreme" leadership.
Why do we choose to ignore Iran's own stated goal to destroy Israel?
Because that's not their stated goal?
