i want to preface this by syaing that i don't necessarily believe in the conspiracy theories around 9/11, but there are some questions that haven't been and probably never will be answered. so to play devil's advocate....
As if US needed to create such a huge catastrophe against itself just to justify going to war in the middle east.
the last thing the usa wants is another vietnam, so in order to get the public to go along wholeheartedly with a war, they could have thought that drastic actions were needed.
al-Queda already took responsibility for 9/11. Move on..
that's irrelevant. conspiracy theorists would say that bin laden was a cia agent. after all, we know he DID indeed work with the cia in the past and so did many taliban-followers.
also, even if this wasn't the case, it is v common for terrorist organisations to claim responsibility. some mad islamic terror group claimed responsibility for the norway stuff, but that was obviously untrue.
I find it rude that people actually make this type of questions. I mean... It's not like 3k died or anything.
why does it matter that 3,000 people died? i mean such a thread would be insensitive at the time, for sure, but 10 years on, surely people can question things? if 3,000 people died, then all the more reason why people would be interested in the event and try to explain it.
