Another view is that this sort of thing demonstrates the irreconcilable differences between us and ISIS, and highlights the differences in our cultures. Our leadership, including Bush, have colluded in pushing a view that this conflict will disappear with better appreciation of the other side's point of view.

One solution is not invasion and land warfare, but isolation and quarantine. Send their adherents whom to the desert and cut off their commerce with the civilized world. Oh, and destroy essential elements of government and economics through aerial bombardment.
But understanding? We already understand way too much.
