What was the point of blowing up WTC7
Destroying three of the most iconic buildings in the world, destroying four aircraft, and killing almost 3,000 people in instances of utter terror was not quite enough to get us Kool-Aid drinkers on board for a strike at Iraq. No, we needed that one last building, empty, to fall, seven hours later. Three buildings, four aircraft and 3,000 people? Ok, but NO MORE! WTC 7 was "the last straw," as they say.
Or, they destroyed all of the 9/11 planning evidence in that collapse. Whatever the truthers say is fine.
By the way, if debris from WTC 2 hadn't hit and perforated WTC 7, causing fires, the U.S. Government would have had no plausible explanation for WTC 7's collapse. Isn't it curious then that WTC 2 seemingly cooperated with the federal government? How did it know that it must eject its debris into WTC 7? What wonderful serendipity that was. I mean, if you believe that Flight 93 was supposed to crash into WTC 7, and that plan was ruined by the selfish passengers, merely trying to save themselves and not onboard with the Iraq directive, then you have to believe the U.S. Government was obscenely fortunate when they ultimately got their WTC 7 "plane crash." Do you think it was dumb luck, or do you believe the U.S. Government controlled the collapse debris from WTC 2 and directed it into WTC 7?
Whatever you believe, you have to ask yourself why the U.S. Government waited seven hours (seven hours!!) to collapse WTC 7, in front of what they must have anticipated would be many news (and amateur) video cameras (read: eyewitnesses who are clever enough---see:truthers---to recognize when the laws of physics are violated), instead of destroying WTC 7 in the midst of WTC 2's considerable dust cloud (when no one would have witnessed the collapse---hence, no pesky questions from pesky truthers). Man, for dudes who planned---and executed, seemingly flawlessly (in regards to operational aspects)---such a complex operation, they certainly didn't seem to be using their brains correctly.
ETA: My comments are not necessarily directed at the OP. I'm sure he knows that.
