We have shown that Islam can rule the world perfectly for 14 centuries, and during this time of Muslim power we did not borrow ideas like democracy from others, so why do we need to learn democracy from them now?
Al Qaeda, the Taliban, a whole host of networks that are bent on attacking America, who have a distorted ideology, who have perverted the faith of Islam, and so we have to go after them.
The Islam that we know is a faith devoted to the worship of one God, as revealed through The Holy Qu'ran. It teaches the value and importance of charity, mercy, and peace.
