in case you haven't added two and two, here it is summed up for you. this hornberger piece tells you some of why 911 was done;


The 9/11 attacks not only killed thousands of Americans, they also led to America’s forever wars in Afghanistan, Iraq, Syria, Libya, Yemen, Iran, and elsewhere, which have brought about the deaths of thousands of other Americans and millions of foreigners. But the 9/11 attacks did more than that. They also fortified the U.S. government as a national-security state, which solidified the destruction of the freedom of the American people.
What is a national-security state? It is a type of governmental structure that has an enormous, permanent military-intelligence establishment. In the case of the United States, that means the Pentagon, the vast military-industrial complex, foreign military bases, the CIA, and the NSA. It also means power — enormous power, not only for the overall government, but also within the governmental structure itself. To place things in a general context, Egypt is a national-security state. So are China, Cuba, and Russia. And the United States.
It wasn’t always that way. America was founded as a limited-government republic, which is the opposite of a national-security state. No Pentagon, no vast military-industrial complex, no foreign military bases, no CIA, and NSA. Just a relatively small army.
That’s the way the Framers and our American ancestors wanted it. The last thing they wanted was the type of governmental structure under which we Americans live today. In fact, if the proponents of the Constitution had said to the American people after the Constitutional Convention that the Constitution was going to bring into existence a national-security state, they would have died laughing, thinking it was a big joke. Once they had realized that it wasn’t a joke, they would have summarily rejected the deal and continued operating under the Articles of Confederation, a third type of governmental system under which the federal government’s powers were so few and weak that the federal government hadn’t even been given the power to tax.........https://www.fff.org/2019/09/10/9-11-solidified-the-destruction-of-our-freedom/
