It is America's war, not George Bush's war or Barrack Obama's war. Terrorists will kill any American they can by any means they can, and care not whether they are Democrat or Republican, Christian, Jew, Atheist, or Muslim. America, no matter what that goofy BHO claims, is still at war. And some, like yourself perhaps, are still debating whose fault it was without, like Obama, having any clear strategy to deal with that reality.

Abdul-Rahman (Peter Kassig) probably wasn't scared either.
Not until he was.
You don't need to be scared to be conquered or killed.
Just unwary and unprepared.
You seem like an advertisement to encourage both.
(Despite any denials, I believe you are a Muslim.)
But, they killed Abdul-Rahman and other Muslims, so why shouldn't a Westernized Muslim worry about ISIS, at least in theory?
