Great literature appears prescient partly because it foretells the future but mostly because we fail to learn from the past. In Conrad’s “Heart of Darkness,” Marlowe comes across a French warship. “In the empty immensity of earth, sky, and water, there she was, incomprehensible, firing into a continent … nothing happened. Nothing could happen.” Fast forward: 6,000 plus American air strikes against ISIS and what has happened? Nothing. Vietnam taught us that you can’t stop history. The de facto partitioning of Iraq is happening. We can slow it down -- contain it, if you will -- but we can’t unwind it.
