Ok 9/11 is definitely another discussion entirely. IMO it was without a doubt a false flag operation. By whom, and how many conspirators were involved (which alphabet agencies) I do not know, but the official story is total crap.
Rather than discuss the pentagon, you guys should talk about WTC building 7. Myself, personally I am tired of having that conversation because usually there is no discussion in it, only extremes on both sides debating their eyeballs out.
