Well...yah see, if you look back at history, these guys flew planes into towers on 9/11. They weren't very nice. So we went to war. NOBODY objected when we went to war over the attacks.
Obama promised hope and change. I personally have very little hope for this country, and certainly no pocket change. That last one is thanks to ObamaCare, the first one is because of Obama weakening our military, distancing himself from our allies, dragging on a war that he could easily have ended and thus draining our economy, and doing his damned best to divide this country. Hell of a legacy.
