The thesis of Webster Tarpley's 9/11 Synthetic Terror: Made in USA has been enthusiastically received with its working model of the 9/11 plot: a rogue network of moles, patsies, and a commando cell in the privatized intelligence services, backed by corrupt political and corporate media elites. This new, fifth edition adds a significant new dimension. Tarpley's documentation of a plethora of 9/11 drills may prove as revolutionary as the thesis of controlled demolition - perhaps even more so. Many people have not been able to see that 9/11 was a false flag. They may seem immune to physical facts like the free-fall speed of the towers, as they take refuge in a lack of engineering qualifications. No math skills are needed to grasp the more familiar, common-sense fact that an act that is rehearsed is also staged. Moreover, understanding how drills are essential to conduit such operations helps us recognize many types of false flags, such as the London bombings, and not only building collapses. Finally, wider public awareness of the dangers and workings of drills could help prevent terror operations, by making them too difficult to carry out with impunity.
