The 911 Report names the Islamist enemy

It took them nearly 400 pages to get to the point, but at least they got there ...

Chapter 12, "What To Do? A Global Strategy" (page 378 of pdf)  "...In this sense, 9/11 has taught us that terrorism against American interests “over there” should be regarded just as we regard terrorism against America “over here.” In this same sense, the American homeland is the planet. But the enemy is not just “terrorism,” some generic evil. This vagueness blurs the strategy. The catastrophic threat at this moment in history is more specific. It is the threat posed by Islamist terrorism —especially the al Qaeda network, its affiliates, and its ideology.
As we mentioned in chapter 2, Usama Bin Ladin and other Islamist terrorist leaders draw on a long tradition of extreme intolerance within one stream of Islam (a minority tradition), from at least Ibn Taimiyyah, through the founders of Wahhabism, through the Muslim Brotherhood, to Sayyid Qutb. That stream is motivated by religion and does not distinguish politics from religion, thus distorting both. It is further fed by grievances stressed by Bin Ladin and widely felt throughout the Muslim world—against the U.S. military presence in the Middle East, policies perceived as anti-Arab and anti-Muslim, and support of Israel. Bin Ladin and Islamist terrorists mean exactly what they say: to them America is the font of all evil, the “head of the snake,” and it must be converted or destroyed.
It is not a position with which Americans can bargain or negotiate. With it there is no common ground—not even respect for life—on which to begin a dialogue. It can only be destroyed or utterly isolated."
