Current focus: Jiang treats history as useful only if it can explain the present and help predict what will happen next. Most connected source readings: **Rome Built an Empire by Turning Wounds Into Weapons**; **The Oceanic Currents Of History**. Nearby topic cluster: Cannae, Hannibal, Prediction, Grand History, Truth. ## Extracted Topic Notes - evidence: Jiang argues Cannae is suspect because ancient surrounded armies should become energized, the tactic lacks ancient parallels, and no archaeological site has been found.
