You know the government creates these groups, right? They never defeated Al Qaeda, but you don't hear about them anymore. They never defeated the group before them, etc etc. ISIS is just the next "group" that's been created to put fear into you and make you hate. Another control tactic. Brainwashing, etc.
I find it funny that a lot of you are the "seeing is believing" type, but just take their word that they actually killed "Osama". But please, continue blindly trusting and following your government without questioning a single thing. Don't do any research! Don't believe your fellow man over them. I mean, the "government", or, the powers-that-be have nothing to lose... right? Why would they ever lie...?
So, the answer to the question is... because there is nobody to bomb. "They" have allowed "them" to exist for so long. Who is "them"? Show me. Show me proof. Bring "them" to my door. Bring the ID. Bring the blood tests. Bring the documentation, the proof, the evidence.
You can't. And I say again, stop accepting what the media is telling you as fact. None of the shit you take for granted as proof or evidence would hold up in court beyond circumstantial. But oh, man, when it comes to this kind of thing, none of that matters.
Yeah. I'm so fucking weird. It would seem that way to the brainwashed sheep, wouldn't it? "Don't question my leaderrrr..."
