No, 9-11 was just an excuse for implementing more fascism in the U.S.
Consider that the U.S. government had the multi-thousand page Heimland (Homeland) Security Act good to go within a week after the event. The U.S. government planned it in advance.
Such actions are not new for totalitarian and wannabe totalitarian regimes. Hitler and the Reichstag fire, for example, helped set up the Nazi regime.
The Hegelian doctrine applied by totalitarian governments is to:
1. Find or create a problem.
2. Depend on the stupid public to cry "save us".
3. Implement a "solution" that increases government power, and that leads to a more serious problem occurring.
4. Loop back to step 2.
That is an infinite escalating loop leading to more and more government power and the public/citizens/serfs/subjects increasingly enslaved and impoverished. Until of course, everything collapses totally. As it has, over and over, in history.
At what level are we now in the cycle?
