Regardless if it was Al Qaeda, or a cover-up conspiracy that seems both rather plausible and extremely unlikely at the same time, the buildings came down and America went to war.
The idea that 9/11 was a self inflicted conspiracy may be attractive as a fiction. But in reality it serves to inflame the wrong side of patriotic feeling. Simply put, 99% or more of Americans felt a sense of great loss as the towers collapsed into the ground. It may have looked like controlled demolitions but that does not necessarily prove that they were controlled demolitions.
Great loss that translated into a terrible anger that been the main news story of the past 10 years. More distracting than the Japanese Tsunami. Not to mention the greatest disaster in history – the 2004 Tsunami and wars in Sudan each involved far greater loss of human life and dignity than either the events of 9/11 or the wars that followed them. And we stopped talking about those events. 9/11 is better “news”.
It is factual that the invasions, especially Iraq, were not what prevented other attacks being planned or being successful. It is also true that they may have made matters more dangerous for a time in terms of both threat and economically.
There is more than one way to conquer a disease. You can kill it with some kind of poison, or you can strengthen the body’s natural defences. The first course of action, typically with antibiotics – seems a valid course until disease evolves that penicillin can no longer touch. Making the immune system more able to cope with disease is a better long term solution.
It is quite true that some attacks were prevented by military intervention, it is true, but when people like Richard Reid (the shoe bomber) were stopped it was mainly due to public awareness as well as less effective planning and execution by Al Qaeda.
A misconception is that the Government protects its citizens, it is probably more true to say that citizens protect their government.
