Depends on the conspiracy. I believe the Saudis were involved, the Israelis were involved, and Bush had some prior knowledge. Building 7 is suspect, and the Pentagon doesn't show a plane..so.

I don't bring these up in conversation though. I discuss it within the mainstream narrative: we were attacked by Al Qeada. But I still want people to understand WHY we would be attacked, and how it was used by criminals to profit, expand power and start wars.
