This single paragraph packs quite a punch:
We Westerners are a people increasingly secular, materialistic, and ignorant of the past. We see all causes as material, all behavior as the result of the physical environment or of psychological forces that also have their origins in immediate material or environmental conditions. Islamic terrorism thus is explained as a response to ignorance and poverty, or to wounded nationalist self-esteem, or to autocratic tyranny, or to post-colonial and post-imperial fallout. The proposed solutions are likewise material: increase development aid to reduce poverty and the despair it breeds; compel Israel to weaken itself in order to remove the constant irritant to Arab nationalist and ethnic esteem; promote democratic institutions to subvert tyranny; and provide rhetorical and fiscal reparations to compensate for colonial and imperial guilt.
