A question from Yahoo! Answers:
How different would life be if the Carthaginians won the Punic Wars?
Not at all. Carthaginians, had they won, would either eventually Romanize or return to Carthage after installing a friendlier government in Rome. Carthage might have had armed forces capable of defeating the Roman armed forces, but it definitely did not have an army big enough to occupy Italy.
Additionally, although Carthage is located in North Africa, its culture is in fact Phoenician. The city was founded by Phoenician traders from Tyre, which is located in present-day Lebanon. The native North Africans, Numidians, were actually at war with Carthage, and de-facto allies of Rome.
