The old appeal to authority. Nice. Well, Dyson is a physicist and mathematician, so his opinion on this matters exactly the same as yours - not a jot.
You're doing a great job of discrediting yourself - no one else needs to even bother.
Say what you want (even though their aims were never to conquer the US), but their tiny little attack scared the US into giving up freedom and entering a war (or two) which caused nothing but fertile ground for more terrorists to attack the US. I'm sure if the terrorists were able to fly a plane into a building which would directly achieve that, and did so, they would have been very happy with the outcome. So yeah - while the terrorists haven't won, they certainly have some excellent allies in the US government.
The American government's response to terror was a pathetic Thatcheresque knee-jerk, and guaranteed more terrorism would follow, all for the measly price of civil liberties. Bargain!
I knew you'd make a post like this. I simply knew it when I saw the headline. Does the plethora of intelligent Irish terrorists in the last few decades show that Catholicism causes terrorism? Of course not. You just have a handy excuse to blame Islam for things you don't like, which you seem to revel in every single time this discussion comes up.
You probably don't realise that your opinion is just as dangerous as the opinions held by the terrorists themselves - you are willing - no, actively trying - to paint nearly 2 billion people with the same hateful brush, and simply refuse to look at the actual evidence.
So as long as there is a worse way of doing something militarily, it's fine? How about if your own shitty foreign policy caused those bad people in the bunker under the apartment block to want to attack you - is it still moral to attack them there?
Oversimplifying this topic isn't doing anyone any favours.
