By largely avoiding the conspiracy speculation that most other authors on this topic fall prey to, Peter Dale Scott manages to meticulously document the events that directly led to the largest mass murder in American history. In "Road to 9-11" the reader is shown that even given the most charitable interpretation of events, and by that I mean one in which we take the findings of the 9-11 commission report largely at face value, one would still be forced to reconcile the fact that the U.S. government recruited, funded, armed, trained, and radicalized a network of Mujahideen guerilla soldiers who were known to harbor very hostile sentiments towards the United States. This very same "Afghan foreign legion" that at one time had been dubbed "freedom fighters" by both president Reagan and Congress eventually evolved into the terrorist network known as Al Qaeda.
Consider, for example, the testimony of Michael Springman, the former head of the American visa bureau in Jeddah, Saudi Arabia. Springman told the BBC that since 1987 CIA had been illicitly issuing visas to unqualified applicants from the Middle East and bringing them to the United States for training in terrorism for the Afghan war. In his words:
"In Saudi Arabia I was repeatedly ordered by high level State Dept. officials to issue visas to unqualified applicants. These were, essentially, people who had no ties either to Saudi Arabia or to their own country. I complained bitterly at the time there. I returned to the U.S., I complained to the State Dept. here, to the General Accounting Office, to the Bureau of Diplomatic Security and to the Inspector General's office. I was met with silence. What I was protesting was, in reality, an effort to bring recruits, rounded up by Osama bin Laden, to the U.S. for terrorist training by the CIA. They would then be returned to Afghanistan to fight against the then-Soviets."
In short, Peter Dale Scott's book is brilliant, not for any new information it brings to the table (in fact much of what is mentioned here has been talked about at length elsewhere) but for the way in which he expertly weaves all of this hidden history (what he calls "deep politics") into a coherent narrative that challenges us to view historical events as more then just a snapshot in time. There's a reason 9-11 happened, and that reason is much more jarring than any theory about controlled demolitions.
