Thats what conspiracists say. Geopolitics is complex stuff... and bad things happen all the time. Thats the way it is. but come on .... we re talking about the US government killing 4000 US citizens to go to war.... dude... US went to war numerous time over the last century (this is just how USA work...) ... if a government wants to go to war... US go to war... no need for such a hoax...

If 9/11 was really a hoax... it would be obvious...
the obvious thing for me is that its way too big to be a hoax...
