"A dude living in a cave in Afghanistan successfully planned a mission in which a bunch of foreign-born terrorists come to the US, live here for years, take flight lessons (learning only how to fly, not how to land), and remain true to their extremist beliefs while living the American life of drinking, strip clubs, and drugs. Then, on a specific day, at a specific time, they hijack a bunch of planes inside the US, using only box cutters, and then crash them into the Pentagon and the Twin Towers. Then the Twin Tower both collapse. And then the US invades (and occupies, wtf) not only Afghanistan, but Iraq. And the US intel community never caught wind of any of this in advance? Riiiiight."
