How can Hannibal's tactics inform modern warfare?
The principles remain. Understand your enemy's intent, his strengths, and his weaknesses. Do not engage his strength head-on; find the pivot point where his power becomes a liability. Adaptability is paramount. The battlefield is a living thing; it shifts, it breathes. A commander must be like the river, flowing around obstacles, or the rock, enduring and unyielding when necessary. Leverage points exist in every conflict, whether it is morale, supply, or the opportune moment. We will always find a way, or make one, to exploit them.
