It matters because 9-11 was a "policy coup." There was no proper criminal investigation of the crime; the evidence was destroyed. Rather than an investigation, we got a prepared myth telling us that Osama bin Laden was behind it all. The real powers behind the false-flag terrorism orchestrated the cover-up and changed U.S. policies to suit their global agenda.
Exploiting an utterly fabricated myth about 9-11, the Zionist Neo-Cons conned the U.S. government into two very costly and disastrous wars in the Middle East. To this day not one of the known conspirators has been prosecuted for their role in waging a criminal war of aggression - the supreme war crime, as defined by the U.S. at the Nuremberg Tribunal.
It matters because the mainstream media, which I call the controlled media, has pushed the official myth and the Zionist fraud known as the "War on Terror" since 9/11. The controlled media has never addressed the very real evidence and facts that disprove the official myth.
