The views of these people are far from what you might expect.
Going back to Ullman's article, he says this:
In simple terms, al-Qaida is symptomatic of far greater changes in the structure of the international system. The major enemy and adversary are no longer states bent on disrupting or dominating the system despite those who see China as a future foe.
Instead, the more immediate danger rests in the dramatic empowerment of individuals and groups, for good and sadly evil, often lumped together as "non-state actors."
Edward Snowden, Bradley Manning, countless "hackers" and anonymous people mailing anthrax-filled letters whose actions have indeed constituted real threats and systemic disruptions are among the former. Al-Qaida and other radical groups reflect the latter.
In essence, the 365 year-old Westphalian system that placed sovereign states as the centerpieces of international politics is being tested and in some cases made obsolete by the empowerment of individuals and non-state actors. As former national security adviser Brent Scowcroft observes, global politics has entered a post-Westphalian era. But very few have taken note and fewer have acted on this realization.
The fundamental cause of this empowerment is the diffusion of all forms of power writ large commonly called "globalization," accelerated by the information revolution and instantaneous global communications and the real and perceived fragilities and weaknesses of states to intervention, interference and disruption by non-traditional actors.
September 11th could become the demarcation point of this new era much as 1648 and the Treaty of Westphalia marked the beginning of the state-centric system of the international order.

It may sound weird for someone to be talking about protecting a world system that dates back to a 17th century treaty.
People like Edward Snowden are now seen as an equal threat, along with Al Qaida, to this system.
I'm not claiming that these ideas are any more sane than those held by the conspiracy theorists,
just that they are held by people in power and people with influence over those in power.
It isn't just the conspiracy theorists that see a new departure since 9/11.
Check up on Ullman, and the influence he and people like him have had.
They are not disregarded kooks, though perhaps they should be.
