From Athena's Terrorism Unveiled, a blog written by an American student living in Amman, Jordan [link from WindsofChange.net]:
"Out of the blue, my host mother asks, 'Who do you think was behind 9-11?' And of course I knew she was expecting me to say 'Osama bin Laden,' so instead I responded, 'Khalid Sheikh Mohammed had a lot to do with the operational planning.' She gave me a quizzical look so I gave her the, 'of course he was one of the top people in Al-Qaida under Bin Laden.' To this she told me that was all a lie and that 'the Israelis are behind this, it's all the Israeli Mossad who did this.' "
