how was hannibal barca able to lose the punic wars even after winning all battles?

Question

hannibal barca was a great leader and won a lot of battles. i am supposed to write a paper on how he was able to lose the war

Answer 1

he also was unable to gather allies against rome adn did not have enough troops to defeat rome, especially after losing over half during the crossing of the alps

and if this is for "great battles that changed westen civilization" in riverhead you could just ask people in the class

Answer 2

He led an expeditionary force, not a conquering one. He did not have the resources to securely hold a strip of territory linking Italy back to Carthage.
