To me, this is the key – 9/11 deniers flatly deny virtually every relevant event in the lead-up to 9/11. They deny that centuries of geopolitical events ever occurred. To them, history begins at the Balfour Declaration, crescendos when Ronald Reagan begins supplying anti-Communist rebels in Afghanistan, and ends when George Bush plants bombs in the North Tower and scampers off in a black helicopter. Between these pockmarks on the historical landscape there are thousands of religious ideologues, millions of oppressed victims of colonialism, and countless strategic opportunists struggling to guide human affairs to their own ends. 9/11 denier history is the shallowest history of all, one that requires them to reject the needs, desires, machinations and schemes of billions of people across centuries. 9/11 denial is reality denial.
