Your ignorance of history is sad, but could be cured by education. The US has long been a corporate imperialist state, exercising it's will on foreign governments and populations through assassination, overthrow of democratic regimes, military invasion, etc., all of which have created the "enemies" we now face.
As the current political and economic situation shows, there is no shortage of extremists and fundamentalists in positions of power in the US.
Please spare us the Beck / Limbaugh / O'Reilly mantra of "they hate us for our freedoms and success". Unless of course you are talking about our "sucess" in stealing their natural resources, killing millions of their people, deposing their democratic governments, supporting their despots (our friendly dictators), etc.
