Who benefited the most from 911 just think about that one for awhile.
It wasn't any of these terror groups sure they got their message out and made a statement and all that but that is peanuts compared to what the US government got out of it, bigger budgets, new agencies, the suppression of that pesky Constitution thing that always gets in their way. Think of all the money being poured into all this security theater they have come up with which any determined somewhat intelligent terrorist could easily deal with. It's all done in the name of 911 to keep us safe what a crock of shit. I'm not one of those people who think the government was behind it I just feel they have been exploiting it from day one to expand their powers and enrich themselves and their friends
