The hard to swallow truth is that ISIS is the US/Saudi government's proxy army. Petraeus moving into the CIA had a good deal to do with this. They arm them, fund them, support them and try to use them to carry out US foreign policy. If you want to be safe from them, you are going to have to do some political restructuring (to put it kindly) right here at home.
Because c'mon now, continuing down this path is going to get us all killed, seriously. The current establishment is sponsoring terror groups that WILL end up attacking Americans, and they are flirting with direct engagement with nuclear armed nations. And for what?
