Time for Hugh Hewitt to do some Koran and Hadith/Sunnah study:

I am just starting to study the above to determine if the "War on Terror" is a war with some Wahhabi "extremists" or whether we are at war with Islam. If we are at war with a proven minority (<1%?) of Islam then our tactics would be radically different than if we are at war with the religion as a whole. If the religion as a whole is hostile to all "infidels" then targeting concentrations of the enemy would be justified, as in any war. I don't think Hugh knows if Muslims who aren't advocating violence against infidels are just "lukewarm" Muslims, or if a minority of Muslims are wrong about their religion, and advocate violence.
