History doesn't support your hypothesis.
I agree, and so does VDH. He takes a swipe at Thomas Friedman, much as I tried to do here:
The next few weeks will show whether the British have advanced as far down the road of dhimmitude as have the Spaniards, who responded to the murder of their citizens not with the force and resistance their ancestors showed for seven centuries, but with fear and appeasement. As for us, we'd better discard our illusions that the jihadists, as Thomas Freidman put it, are “a cancer within the [Islamic] body politic” and accept instead that jihad just may be a vital organ. -- from the thread's article by VDH
Conquest is a vital organ of this religion. A few offshoots like Sufism downplay it, but in Shia and Sunni, it's right out there with bloody swords on the foreheads of children and black flags.
