I'm not sure if this has ever been shared here before, I apologize if so. A search of "noam chomsky" came up with no threads specific to this video. Noam makes a pretty solid argument as to why the obvious use of 9/11 to further questionable national security objectives is not evidence that it was planned by the government. We as the public should be well aware by now that tragedies are often used to further political agendas, because people want action and that directly translates into votes for the most vocal. But that doesn't mean they planned the attacks, it just means that (as expected) they exploited them - and, as he explains, so did every other country in the world.
