Culture of Fear

I do not have much to say about the anniversary of 9/11, but here you can read why I believe this incident still leaves many questions unanswered.
What I find startling though from my own present perspective, is that this event which happened five years ago gave the green light for the US government to fight three simultaneous wars. Afghanistan, Iraq and the war on Terror. None of them winnable except maybe the war on terror if the mindset of people in charge understood anything about history, culture and additionally would aim to work towards peace. Therefore it is this last one, the war on Terror that bothers me the most where all energy is funneled into an abstraction of fear instead of creating new thoughts and strategies. As the administration widens the front of conflict, it almost seems that they do this with a purpose. You see, all the actions now equal to that people must remain living in perpetual fear, fear from an invisible enemy they can't even address.
Dominance of fear amongst the population makes people act like slaves, following the demands that come from above.
"We have nothing to fear, but fear itself!" Which president said that?
I don't think that the founders of this country had oppression and fear in mind, at least I can't find it in the constitution - no matter how hard I look.
