From the last paragraph of Victor Davis Hanson's In Their Own Words - Newly translated writings of the al Qaeda leadership:
What kind of words? Bin Laden:
The Al Qaeda Reader, simply by letting our enemies speak in their own voices, explodes the popular delusion that Western crimes and policies are responsible for the “distortion” of Islam that al Qaeda represents. As Ibrahim writes, “This volume of translations, taken as whole, prove once and for all that, despite the propaganda of Al Qaeda and its sympathizers, Radical Islam’s war with the West is not finite and limited to political grievances — real or imagined — but is existential, transcending time and space and deeply rooted in faith.” This means that the fight will be long and hard, that leaving Iraq or creating a Palestinian state will not buy peace, and that the side that accurately understands its enemy and has confidence in its own beliefs will ultimately triumph. Thanks to Raymond Ibrahim’s The Al Qaeda Reader, we have the means for achieving that understanding.
“As if one of the foundations of our religion is how to coexist with infidels!” Quite the contrary: the traditions and foundations of Islam urge believers to “wage war against the infidels and the hypocrites, and be ruthless against them” (Koran 66:9), a verse Zawahiri quotes along with the commentary of al Qurtubi, 13th-century author of a 20-volume exegesis of the Koran: “There is but one theme — and that is zeal for the religion of Allah. He commands the waging of Jihad against the infidel by use of sword, sound sermons, and the summons to Allah.”
On "working together"
Indeed, bin Laden has a strong case, for he appeals for evidence to the life and practices of Mohammed and his companions — along with the Koran the Muslim’s guide to every aspect of life — and asks sarcastically, “What evidence is there for Muslims for this [dialogue and shared understanding]? What did the Prophet, the companions after him, and the righteous forebears do? Did they wage jihad against the infidels, attacking them all over the earth, in order to place them under the suzerainty of Islam in great humility and submission? Or did they send messages to discover ‘shared understandings’ between themselves and the infidels in order that they may reach an understanding whereby universal peace, security, and natural relations would spread — in such a satanic manner as this?”
History shows that bin Laden has the better understanding of Islam than do Western apologists; as Ibrahim summarizes the argument, “‘radical’ Islam is Islam — without exception.” In this same vein, Zawahiri argues in his “Loyalty and Enmity” that the only relationship one can have with the infidel is enmity. Zawahiri buttresses this argument with numerous quotations from Islamic theology, the most important coming from the Koran 60:4: “‘We disown you and the idols which you worship besides Allah. We renounce you: enmity and hate shall reign between us until you believe in Allah alone.’” On this authority comes the necessity to wage jihad against the infidel.
Let's recall the words of al Qaeda's leaders the next time a liberal professes that there is no conflict between Islam and the West, or that if we just left their country, everything would be just fine. These men have clearly laid out a theological excuse for their mayhem and murder, irrespective of American actions to protect its strategic interests in the region.
That is false, as bin Laden and Zawahiri themselves prove in their own words.
