The FBI has infiltrated all White Nationalist/Supremacist type groups from top to bottom, so anything they do happens with the FBI's implicit approval. For example, in the recent 'kidnapping attempt' of Michigan Governer Whitmer, the most active conspirator
was an FBI agent! There are plenty of reasons to suspect the FBI as the true mastermind of the OKC bombing and the 1993 trade towers bombing, but not 9/11 - that was the CIA . . . .
