1.) There were not that many in the know; not even low CIA intel. officials were in the know, though the higher-ups of nearly all intel. agencies around the world know that Mossad and Zionist Jews with connections to Israel and the neocon pnacers were the perpetrators. That being said it was likely US intel was involved but on a compartmentalized effort.

9/11 was Purim against the Goyim to initiate the Yinon Global War on Terror.

9/11 was also a convenient atrocity event for other figures with their own geopolitical agendas to latch on and use it as a catalyst.

2.) Anthrax attacks: Read Graeme MacQueen's book 'The Anthrax Attacks a Case for a Domestic Conspiracy.' It was likely Zionist Jews who orchestrated this attack such as Phillip Zacks and other agents. The neocon Donald Kagan was the first to say Al Qeada and Iraq had Anthrax and would use it on the population, he also linked anthrax to the 'hijackers' which was the offeiinal pre-fabricated narrative but indepedent agencies started to discover that the Anthrax was domestic and the neocons nearly outed themselves. The FBI then covered it up because as I've come to understand it, the US government is not always that cozy with neocons or Zionists Jews with foreign ties to Israel, espeically not investigatory agencies but nevertheless, they don't want to look incompetent and stupid, so they cover it up.

3.) Two books prove who killed JFK and why. Michele Metta's 'CLAY Shaw and the CIA Mossad station' and Michael Collin Piper's book 'Final Judgement.'
