As in all religions believers fall into two groups. Those that say they believe but do not obey scripture to the letter and those who obey scripture as written. The ones who follow the Quran to the letter are the ones who want world domination of Islam. Those wish to kill the infidel for they believe they are commanded to do so. They are called radical because they obey what they believe their god has decreed. Radical Christians on the other hand are taught to love their enemy. In my understanding of the whole mess. For that reason there shall never be peace with the hard liners unless you believe as they do.

For starters, the Crusades to the East were in every way defensive wars. They were a direct response to Muslim aggression—an attempt to turn back or defend against Muslim conquests of Christian lands."
The followers of Islam caused the Crusades through aggression and the taking of Jerusalem.
The followers of Islam continue fighting among themselves to this day.
Now the followers of Islam have their sights set on the conquest of America and world dominance. It is for nothing that we did but for what we do not do, we do not bow to Allah.
The sin of the world and the true cause of Islamic aggression is to remove the infidel from the earth for not following Allah. For that reason we can make every excuse in the book for the aggression but we only fool ourselves in doing so.
