The terrorist mentality is that of a cornered cat lashing out in psychotic desperation. It matters not if there is anything actually cornering it, or at what it lashes out. All that matters is that it must perpetuate its own self-image as a martyr willing to die for some lofty ideal, fighting against a cruel and oppressive tyrant, or else risk going back out into the mainstream, undisturbed (an uninteresting) cat population, so to speak. No war and no cause means no axe to grind, no international attention, no subversive and twisted sympathy, no inflated sense of self-importance. If that means they have to paint some entity (Israel, USA, Western Powers, Russia, etc.) as the cruel oppressor to make the whole fantasy work, then so be it. If that means they have to mow down thousands of innocents at a single stroke in the name of so-called martyrdom, so be it. The whole lot couldn't pass a psyche exam on a bet.
