All three World Trade Center Towers (1, 2, and 7) collapsed after being detonated with explosives in less than eleven seconds each. Such destruction is only possible by controlled demolition, not by keresene (jet fuel) office fires or plane crashes. These three controlled demolitions were obviously set by trusted insiders who had the necessary security access to the elevator shafts and core columns, where explosives would have to have been planted to detonate the three towers, and a 9/11 investigation would be required to determine who planned and executed the controlled demolition of the World Trade Center Towers on 9/11-betting not any muslims or anyone from Iraq (as claimed by Bush Jr) or Afghanistan (as claimed by Obama).
