They didn't do it because we are so rich and so free, as the neocons would have us believe. They came over here because we had been killing Muslims "over there" for decades.
How do we know this? Well, they told us. Osama bin Laden made it clear why al-Qaeda sought to attack the US. They didn't like the US taking sides in the Israel-Palestine conflict and they didn't like US troops on their holy land.
Why believe a terrorist, some responded. As I explained to Giuliani ten years ago, the concept of "blowback" is well-known in the US intelligence community and particularly by the CIA.
Unfortunately, it is clear that Giuliani never really understood what I was trying to tell him. Like the rest of the neocons, he either doesn't get it or doesn't want to get it. In a recent speech to the MeK – a violent Islamist-Marxist cult that spent two decades on the US terror watch list – Giuliani promised that the Trump Administration had made "regime change" a priority for Iran. He even told the members of that organization – an organization that has killed dozens of Americans – that Trump would put them in charge of Iran!
