I never knew Bush was so talented and here you have him inventing Islamic extremism.
Now can I be serious for a second? Ready?
Q:Is ISIS here? Is ISIS in Mexico?
A: IT DOESN'T MATTER!
Why doesn't it matter? Because the execution of terror planning has morphed. Would Islamic extremists (AQ, ISIS, et al) love to carry out more 9/11 style atacks on American soil? Of course. But what's most important is spreading their sick message of hate, mostly through the internet by targeting weak-minded people who are upset and angry about anything, and think this is the way to inject some shot of hope into their lives. They can travel to some far away Arab nation to be further indoctrinated, or pick up a rifle or a machete and carry out a barbaric act here. And by many measurements this recruitment drive is succeeding. Can you be done with Bush now?
