Fighting the "War on Terror" starts at home. If the U.S. wants to stop attacks on itself it should stop attacking others, especially those who have done us no harm nor have the capability to do so. The list of innocent nations is long, and the number of innocent people we've slaughtered for lies our gov't told surpasses millions.

"The greatest purveyor of violence on Earth is my own government." 
Telling the truth often angers those who it inconveniences.
The gangsters running this country didn't care about his civil rights demands, but when he threatened to cut off the supply of black bodies to fight the oligarchs global resource wars, that was his death warrant.
Only the naive, ignorant, and blindly xenophobic ask "Why do they hate us?"
