America is in denial
America is in denial. After all, Michael Moore http://www.michaelmoore.com/ made a hollwood documentary-Farenheit 911, exposing some corruption behind President Bush and his administration. Americans choose to stay in the dark because if the light is turned on, there is no way to run, the problem now has to be faced.

The solution is in the hands of our future leaders
In college, I took a class called terroism and politics and I probably have more knowledge about this topic than the average person. It's pretty complicated. However, a lot of past conspiracies have been swept underneath the rug. The only thing we can really do for the future is put better quality people in office and keep a closer eye on them.
